engine igintion problems, need help!

[burnok]

I have a 94 lancer glxi (4g92a engine) na bigla na lang di na umistart , ok naman po yung starter dahil it cranks the engine normally para umistart kaya lang di tumutuloy. I have inspected kung merong spark sa high tension wires leading to the spark plug and there was none., so a mechanic tried to replace the ignition coil thinking na yun ang sira pero it still would not start, so ibinalik na lang uli yung luma.

Another mechanic told me na baka ecu ang defective but the check engine lights goes on after turning on the key and goes off after 5 seconds (which is an indicator na ok ang ecu, correct me po if I'm wrong) , so medyo hessitant ako na bumili agad ng ecu dahil medyo mahal din.

Ano pa ba ang pwedeng pagmulan ng sira nito aside from the ecu and ignition coil? TIA

my ignition coil yan? dba direct na nasa distributor yung coil nyan?
Dude natry mo na ba i-check ung fuel pump sa loob ng gas tank? baka un ang sira,, para mcheck mu pump, disconnect mo ung fuel line sa filter jan un nakakabit sa body sa likod ng makina, start mu dapat mu lumabas na gas if not fuel pump sira.. 15k for the brandnew fuel pump

try mu din pala linisin ung fuel filter baka clogged na...


also try checking your existing power cable

ECU nyan 20-40K sa mitsubishi (brand new) di ko alam if magkano surplus

Yup sir internal nga ignition coil nya.
Ok naman yung fuel system nya, problem lang talaga is walang kuryente from the ignition system.

check mu yung socket sa ilalim ng distributor nagiinit ba un? baka grounded yan,,,
or loss connection lang yan?
tiga san ka ba? mas mabuti dalin mo yan sa mga auto center na jan specialization,, mahirap kasi itrace yan..

kaso baka tama ka nga na ECU prob nyan.. prepare ka ng budget

Start from the most basic bro, check mo muna ang battery, then battery terminals, then distributor cap, then hi-tension wires, then alternator, then ignition coil solenoids. Hindi yan sa ECU bro believe me, bopols yung mekaniko na nagsasabi sa iyo na ECU yan. Your problem has something to do with your electricals, charging system, and grounds. Hope my suggestion helps.

[speedyfix]

the the relay and fuses.. also check the fuel pump.

[burnok]

Thank you very much mga Bros. for the replies

Things I have already checked/done on my engine
>Umaabot ang gas sa combustion chamber dahil amoy gas when I crank with the plugs disconnected
>battery charge and clamps are ok
>fuses are all ok
>CEL lights on for 5 secs after turning on the ignition and goes off after 5 seconds.
>no spark present in HT wires leading to the plugs, pinalitan na ang coil but di pa rin umistart kaya ibinalik na lang ang lumang coil.

Gusto ko sanang i-check ulit yung primary and secondary winding ng coil but I dont know how (internal kasi yung coil and hindi ako familiar sa terminals), can somebody tell me how to do it? TIA

[mazingerZ]

check mo ang distributor bro. .

[mazingerZ]

Here are some suggestions din bro (taken from my Haynes Workshop Manual for my vehicle):

Engine rotates but will not start:

1. Fuel tank empty;
2. Battery discharged (engine rotates albeit slowly);
3. Battery terminals loose or corroded;
4. Fuel not reaching carburator or fule injectors; check for clogged filter or lines;
5. Choke not operating properly;
6. Faulty distributor cap and rotor;
7. Low cylinder compression;
8. Valve clearances not properly adjusted;
9. Water in fuel; drain tank and fill with new fuel;
10. Defective ignition coil;
11. Dirty/clogged carburator or injectors;
12. Wet or damaged ignition components;
13. Worn, faulty or incorrectly gapped spark plugs;
14. Broken, loose, or disconnected in the starting circuit;
15. loose distributor;
16. broken, loose or disconnected wires at the ignition coil;
17. Timing belt failure;

Subukan mo muna ang distributor cap bro. Tantya ko dyan ang problema. HTH.

[burnok]

Today I tested the high tension wires that leads to the spark plugs and two of them registers high resistance while the other two registers low resistance, alin po sa kanila ang normal/faulty? Eto na po kaya ang dahilan ng hindi pagstart ng oto ko?

Maraming salamat po uli sa mga nagreply!

[mazingerZ]

Better buy a new set of HT wires with a new distributor cap na lang. Mura lang naman bro.

[burnok]

I borrowed a known good set of HT wires from a friend and installed it in my engine, still no spark is generated.

I also tested yung terminal mismo ng ignition coil (the one in a tube leading to the distributor cap then to the rotor center, also no spark was present. So the the route from the spark plugs to the high tension wires to the distributor cap being defective is eliminated.

Paano ba i-check ang windings nang igintion coil (di kasi ako familiar sa terminals ng internal na ignition coil.) TIA

[userfriendly]

better have an auto electrician check your car.

[mazingerZ]

Follow mo na lang bro suggestion ni sir userfriendly, mukhang mahirap butingtingin na kasi nag linya at ang ignition coil mismo.

hey bro, did you guys check if theres any power going to the Distributor?? (.5 volt reference signal) also, did you check the Igniter??

anywayz, theres a possiblity that the Distributor assembly can be faulty (which is the same on some Ignition related problems on Honda's... which is traced back to the Distributor assembly).



aite, peace.

bro,you mean to say signal from ecu to distributor(.5v)?possible problem from ecu unit?loose connection,cold solder or defective electrolytic capacitor.thanks.....

[burnok]

I have downloaded a manual for lancer and from there, I found a portion which deals on troubleshooting a so called power transistor using a 1.5 volt battery and an analog multimeter.

So tinest ko nga po ito by using the terminals on the distributor cap connector and from the instruction details sa manual, faulty raw ang power transistor ko.

My question is, Saan po ba located ang power transistor? Nasa loob po ba iyon ng iginition coil housing?

Gusto ko kasing ipatest sa Banawe yung part and bumili na rin kung sira nga po ito. TIA

[burnok]

OK na po yung kotse ko

yun palang terminal na tinest ko yun na pala ang mismong igniter.

sira nga yung igniter nung engine ko, so punta ako ng Banawe para bumili, I got a surplus for P1400.00. Pagkakabit ayun umandar na agad.

Good thing di pa ako nakakabili ng ecu, It really pays to be kuripot sometimes

Thanks po sa lahat ng nagshare ng ideas!!!

congrats bro. di naman pagiging kuripot yung ginawa mo. you're just being wise.

nice! tama nga yun hinala ko, yung Igniter ang talagang culprit diyan. its the same on Toyota's and Honda's. ang Igniter talaga ang madalas masira sa Ignition System.

glad to know that yer car is back on the road again!
