Diesel Fuel Injection System Help Desk

Hi sir Jake,

Diba TOYOTA and MITSUBISHI are the one equip with this Pump? Depende kung anong model ng sasakyan at makina ang tinutukoy mo. Toyotas D4D and MITSUBISHI DiD. Denso ang system ng D4D and DiD.

Ask ko na din how would you know if mdyo sakal (under fuel delivery) ang pag calibrate ng isang pump? Kung walang bara ang fuel filter, tank, and lines, ang mga palatandaan ng sakal ay low power, slow acceleration, at walang kausok usok. Kelangan din natin yung konting smoke sa acceleration dahil ito ang extra fuel na nagbibigay ng power. Sir meron naman konti usok pero parang mabagal pa din ang acceleration

Mdetect po ba ito kahit hindi i pull out ang Pump? Pwede madetect ito kung old style rotary pump. Hindi it madetect kung common rail ang system. Pano po ma detect un rotary type naman po pump ko.

[SIZE=2]Kunin mo yung part number ng pump tapos ipost mo. Ano ba ang car mo? [/SIZE]

Thanks, You're welcome.

Sir bighorn po, 4JG2 engine.. bosch/zexcel VE pump po ung nakalagay.
check ko ung part number nya tapos i post ko dito.

Thanks..

check ko ung part number nya tapos i post ko dito.

Thanks..

[SIZE=3]4JG2 uses a rotary pump, either mechanical or electronic, depending on the model. Matutumbok natin ang pump pag napost mo ang part number.

I would like to help! Throw in your questions regarding problems with your fuel systems (injection pumps/ injectors/ turbochargers/ electronic systems/ etc.....) Then you guys take it from there...................if I can be of help, why not!

ey diesel dude..need ur expertise..we own a mitsubishi l200 1995..quite old..have been to the calibration twice already..recently last month..ask ko lng, may pag-asa p bng luminis yng usok? pansin ko kasi parang nabawwasan after calibration..pero pag nagkamali ako ng shifting, umuusok p rin..worry ko takot tuloy ako dumaan ng c5 kasi ang daming nanghuhuli..

ano b ang kailangan kng ipacheck para maging usok free n talga ako..o hindi mangyayari yun? may alam k bng pde kng puntahan para ipacheck and yng hindi nmn over maningil? tnx

[daniel_garcia78]

Blocked fuel filter or faulty injection pump. Check fuel filter first.

sir mas ok po b tlaga yng crdi kaysa sa conventional diesel engine? nagbasa kasi ako ng review ng toyota's d4d sa hilux n innova..ang daming horror stories like engine knock, biglang humihinto yng makina tpos yng isang [papunatang baguio, nabitin yata..

plan kasi ng mom ko bumili ng innova..pro after reading the reviews..parang napa isip kmi..last sunday nagpunta kmi sa car show sa fort..nakita namin yng montero n san ta fe..ano kaya ang mas ok bilhin? sabi kasi ng danta fe agent, mas fuel eficient daw sila and combortable ang ride?
thanks

ey diesel dude..need ur expertise..we own a mitsubishi l200 1995..quite old..have been to the calibration twice already..recently last month..ask ko lng, may pag-asa p bng luminis yng usok? Of course may pagasa yan.

pansin ko kasi parang nabawwasan after calibration..pero pag nagkamali ako ng shifting, umuusok p rin..worry ko takot tuloy ako dumaan ng c5 kasi ang daming nanghuhuli.. Talagang normal lang na may konting usok, lalo na sa acceleration. Kelangan lang pumasa yan sa smoke emission test equipment.
Maaring pasado din naman ang car mo sa smoke test, at hindi mo lang alam.


ano b ang kailangan kng ipacheck para maging usok free n talga ako..o hindi mangyayari yun? Check/replace air filter, tune-up engine, check injection pump and injectors, dahil baka hindi tama ang pag calibrate ng injection pump and injectors mo?

may alam k bng pde kng puntahan para ipacheck and yng hindi nmn over maningil? tnx. Pm kita.

[Dieseldude]

sir mas ok po b tlaga yng crdi kaysa sa conventional diesel engine? Shempre naman, ok talaga ang CRDI engines.

nagbasa kasi ako ng review ng toyota's d4d sa hilux n innova..ang daming horror stories like engine knock, biglang humihinto yng makina tpos yng isang [papunatang baguio, nabitin yata.. Totoo yan.

plan kasi ng mom ko bumili ng innova..pro after reading the reviews..parang napa isip kmi..last sunday nagpunta kmi sa car show sa fort..nakita namin yng montero n santa fe..ano kaya ang mas ok bilhin? Basahin nyo ang mga posts sa Tsikot, tapos mag decide kayo. Mas mahal ang Montero at Santa Fe kaysa sa Innova.

sabi kasi ng santa fe agent, mas fuel eficient daw sila and combortable ang ride? Shempre sasabihin yan ng Santa Fe agent. Pero maaring totoo din ang sinasabi nya. Mabuti nga na nandito ang Tsikot para makapag survey kayo.

thanks

Hi Dieseldude. Need your help. I was one of those who unfortunately got my Pajero submerged (near the roof for ~ 6 hrs) last September. Got it running after ~2 weeks but has had some problems once in a while. Last wednesday, after a few minutes of drive, the AT light started blinking so after driving for awhile to drop off my brother, i went back home. But i noticed that it was not shifting correctly already and it had a hard time getting up our driveway which has a small incline. I checked the ATF and it was full. I started it again, the blinking stopped and the power is back. Yesterday, we changed the ATF but didn't help much. The problem is intermittent. What should i check/do? Thanks.

I would check the throttle potentiometer for loose/broken wires. This is a black round thing with three wires, mounted on top of the injection pump's control lever. Don't loosen the 2 mounting screws or adjust it's position; this is critical. This device detects throttle position and sends a signal to the transmission control unit for proper shifting.

Update us if your fix is successful.

Sir may Idea po ba kayo kung panu malalaman kung tama ang position ng potentiometer sa isang sasakyan?


Thanks..

Sir may Idea po ba kayo kung panu malalaman kung tama ang position ng potentiometer sa isang sasakyan?

Thanks..

Hindi ko ma-explain ito sa iyo. Meron specific electronic calibration data para sa throttle potentiometer. Nasa test specifications ito ng injection pump. Ginagawa ang adjustment habang naka salang ang injection pump sa test bench.

sir,meron kasi ako problema ngayon, its about the diesel injection pump ng toyota lucida ng office...ganito kasi ngayari...after ondoy eh ginawa palang bangka ung oto,inilusong sa baha after nun nag hard starting siya, so pinatingin sa mekaniko,ayun di check yung makina,wala daw kuryente yung injection pump so tumawag ng electrician,check yung computer box baka kasi yun ang sira,eventually nagkakuryente,di inistart ayun gumana yung makina,after ilang test, biglang naputol yung timing belt..nakow...binuksan yung overhead, putol ang camshaft, baluktot 3 valve and may tama yung 3 valve lifter,so pinaayos yun at bumila ng mg pyesa.so ok na,eto ngayon bago pa pala nabaha eh nakargahan ng gear oil yung makina instead na engine oil...bumili na rin ako ng surplus na injection pump ang kaso hindi daw consistent yung buga ng krudo...ipa calibrate daw...ang kaso wala nagcacalibrate dito sa cavite na alam ko puro mechanical lang, sabi naman dun sa isang calibration shop ipa check ko daw yung computer box kasi baka yun daw ang sira, tanong ko lang paano ba ang gagawin ko? cant read back kasi medyo mahaba na itong thread and medyo nagmamadali na ung boss ko...is it the injection pump ba or the computer box?ano pwede remedy or solution sa prob na ito...tia

[Dieseldude]

sir,meron kasi ako problema ngayon, its about the diesel injection pump ng toyota lucida ng office...ganito kasi ngayari...after ondoy eh ginawa palang bangka ung oto,inilusong sa baha after nun nag hard starting siya, Masisira talaga yan dahil ginawang bangka ang kotse.

so pinatingin sa mekaniko,ayun di check yung makina,wala daw kuryente yung injection pump so tumawag ng electrician,check yung computer box baka kasi yun ang sira,eventually nagkakuryente,di inistart ayun gumana yung makina,after ilang test, biglang naputol yung timing belt..nakow...binuksan yung overhead, putol ang camshaft, baluktot 3 valve and may tama yung 3 valve lifter,so pinaayos yun at bumila ng mg pyesa. Poor maintenance. Dapat pinapalitan ang timing belt on schedule.

so ok na,eto ngayon bago pa pala nabaha eh nakargahan ng gear oil yung makina instead na engine oil...Hay naku. bakit ganyan ang mga tao nyo?

bumili na rin ako ng surplus na injection pump Bakit ka bumili ng IP? Pwede naman ma repair yan.

ang kaso hindi daw consistent yung buga ng krudo...ipa calibrate daw... Paano kaya nalaman ng mekaniko ma na hindi consistent ang buga? May test equipment ba sha? Ibalik mo sa tindahan ang injection pump at papalitan mo kung sira talaga. Wala ba silang warranty?

ang kaso wala nagcacalibrate dito sa cavite na alam ko puro mechanical lang, Dalhin mo ang IP sa Manila. Pwede ma repair yan.

sabi naman dun sa isang calibration shop ipa check ko daw yung computer box kasi baka yun daw ang sira, Paano naman nahulaan ng calibration shop na sira ang computer box?

tanong ko lang paano ba ang gagawin ko? Palitan or turuan ang mga driver at maintenance personnel nyo. Sisirain nila lahat ng sasakyan ng kumpanya.

cant read back kasi medyo mahaba na itong thread and medyo nagmamadali na ung boss ko...is it the injection pump ba or the computer box? I don't know. HIndi natin ito kaya idiagnose basse sa post mo lang.

ano pwede remedy or solution sa prob na ito...tia. Dalhin mo ang Lucida sa matinong workshop, hindi sa manghuhula. Kawawa ka naman.

[lagim_29]

sir,saan kayang shop pwede dalhin yung IP?can you give me the name of the shops?tnx

hi sir dieseldude,

am another diesel newbie, and i find this thread very helpful, enlightening and entertaining.

my ride is a '02 crosswind xuv turbo a/t with 61k odo reading. eto po ang problema ko - above 2.5 rpm hirap ung makina, kaya hanggang 80-90 kph lang ang takbo nya. pero below 80-90 kph, smooth running naman. kaya lang, kahit nakatigil lang at i-rev, hirap sya above 2.5k rpm, parang kinakapos o nag-hehesitate, erratic ang rpm between 2.5k and 3.0k when the pedal is floored. when running at that rpm range, parang naghihingalo.

bago ko naramdaman yun, i had an oil change at 60k sa suking service station using shell helix diesel plus 10w-40 last september. i first noticed this problem when i went to lucena last week, while at slex. pagbalik ng manila, chineck ko engine oil tsaka ko lang napansin lampas sa max level yung langis (halos kalahatian ng min max range ang inilampas). pina-drain ko sa mekaniko hanggang max lang. medyo nag-improve, pero ganun pa din, hirap pa din sa 3.0k rpm, di ko mapalampas dun.. gaano ba kasama na lampas sa max ang engine oil, especially with turbo?

last week, pinalitan ko yung air filter ng original sa walco. pero ganun pa din. ano kaya problema, tsaka ano dapat gawin? any advice will surely be appreciated.

maraming salamat po.

Sobra ba ang nailagay na oil? Or dumami ang oil? Dahil kung dumami ang oil, meron fuel dilution.... ibig sabihin, nag lealeak ang diesel fuel papunta sa oil pan. So check mo ulit ang dipstick kung dumadami pa rin ang oil.

medyo nag-improve, pero ganun pa din, hirap pa din sa 3.0k rpm, di ko mapalampas dun.. gaano ba kasama na lampas sa max ang engine oil, especially with turbo? Hindi naman. Masama kung sobra sobra ang lampas dahil papaluin na ng crankshaft ang oil. Mag fofoam ang oil with air bubbles at kukulangin ng lubrication ang engine.

last week, pinalitan ko yung air filter ng original sa walco. pero ganun pa din. ano kaya problema, tsaka ano dapat gawin? any advice will surely be appreciated. Try mo palitan ang fuel filter. Baka barado na ito kaya kinukulang ng fuel ang engine.

maraming salamat po. You're welcome.

sobra nailagay na oil, dahil hindi na sa dumami after periodical dipstick check.

Masama kung sobra sobra ang lampas dahil papaluin na ng crankshaft ang oil. Mag fofoam ang oil with air bubbles at kukulangin ng lubrication ang engine.
ah ok, akala ko ganun kasama dahil may caution sa user's manual na di dapat lumampas sa max. ala naman akong na-observe na foaming at air bubbles sa dipstick.

last week, pinalitan ko yung air filter ng original sa walco. pero ganun pa din. ano kaya problema, tsaka ano dapat gawin? any advice will surely be appreciated. Try mo palitan ang fuel filter. Baka barado na ito kaya kinukulang ng fuel ang engine. ok will do this asap.

Sir Diesel Dude,
My ride is a "95 Pajero TDIC M/T Local version. with 4d56 engine

Ask po sana me advice abt the starting problem..

Every morning daw po kc hirap daw istart.kelangan pa daw po i heater many times, atleast 20 times para mag start.. ok naman daw po battery and starter kc malakas naman redondo kapag try starting ilang beses, kaso hirap talaga magstart..

pina check narin po namin sa mekaniko..ok naman daw po battery..check nya rin glow plugs and ok pa naman daw po. actually kapapalit ko lang po ng glow plugs last 4 months..hindi naman cguro loose compression kc d naman nagbabawas engine oil..lagi po namin minomonitor oil dipstick and d nagbabago oil level for almost 3 months na.

kapag nagstart na engine after several heating cycles, ok naman po takbo.wala naman pong problema while engine running..sa starting lang po talaga..odometer reading po is 131640kms..

btw, wife ko lang po kc nagsastart ng engine every day,,she just reported about the problem when i called..ofw po kc me sir and it happened our vessel docked in vancouver.. Salamat and nagkaron dn ng chance makapag internet kaya kayo po kagad naisip me hingan ng advice..Ive been reading your thread always pag nasa pinas po me kc interesado po me abt auto engines..marine engr po kc me..

ano po kaya sir posibleng problema para ma bigyan po natin ng tamang remedyo..and ma relay ko po kay kumander ano magandang gawin next time pagtawag ko po jan satin..

Maraming salamat po in advance sir.. God bless

[eugene emmanuel]

Btw sir, every morning lang po hirap istart ang engine..pero kapag nag start na ang engine and nakatakbo na..throughout the day hindi na po hard start..ngayon lang po kc namin na experience starting prob..since nabili namin unit last may..

[quimat]

sir dieseldude, salamat po an andyan ka.
meron po ako problema sa 2008 dmax ls 4x4 ko.
may time po na kinakapos sya sa power.
prang napuputol po yung supply ng diesel.
minsan po pag mabilis ang takbo, nabibitin.
minsan po pag mabagal ang takbo, namamatay.
ano po ang dapat kung gawin?
magpalit na po ako ng fuel filter, at sinunod ko rin ung instructions sa pag bleed sa manual.
dadalhin ko na po sana sa casa, pero hintay ko po muna advice mo.
maraming salamat po. god bless you. tsup.

1. Check actual condition of glow plugs kung ok ito maski na napalitan mo na. Maraming palpak na glow plugs binenenta sa market.
2. Verify mo din kung may current sa glow plugs during "on" and "start position" ng ignition switch. Baka walang kuryente.
3. Kung walang current, check glow plug relay and glow plug electrical circuit.

Maraming salamat po in advance sir.. God bless You're welcome.
