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!

hello to every one, i was back reading this thread mula ng makabili ako ng 2nd hand fuego, may tanong lang po ako bakit kaya hindi stable ang idling ng makina? mapapansin ito sa tunog. kahit patay o bukas ang AC. normal po ba ito? fuego 1998 4x2 po ito. nabili ko nitong june. salamat po

Hi Everyone,

Ask ko lang po kung may naka experience at ano ang possible problem. We have a company

delivery van Isuzu elf 4jb1 mileage 200k. the injection pump already calibrated. the problem is

if on idling for 15 to 20 minutes engine will shut down, sa restart you have to pump the sedimentor pump

to start the engine. it seems nauubusan ng fuel going to the injection pump. But if choke knob is adjusted to higher rpm ( 750rpm) it will be fine.

yung low idling like niya nasa 500rpm lang after 15 to 20min mamatay engine.


thank you

did you try troubleshooting the fuel pump?

Sa may fuel filter, mayroon ka ba ng water separator? May flap valve dyan na minsan needs adjustment or minsan may tumukod na dumi

Sir Dieseldude (or kung sino man makakatulong)

Drive a Gen 1 Montero Sport ('99) with a 2.8L 4m40. Ngayon, bigla na lang siya namamatayan pag umaga (or pag mga 1 day na naka parada), hindi naman siya hard starting 1 - click pa din siya, wala din usok white or black, wala talaga. Normal ang tunog, ang difference lang talaga grabe yung vibration pag umaga, tsaka yun nga namamatayan minsan (mas namamatayan pag hindi pa half yung temp. tapos binuksan ko yung aircon) . Last na calibration ko was mga 2011, namamatay matay din siya dati, pero maitim yung usok tsaka hard starting na siya nun. Ngayon hindi, kaya medyo nalalabuan ako.

Thanks in advance!

Check your coolant temperature sensor reading when you think it will have the symptom. It might be indicating a lower resistance than normal when the engine is cold, or, try disconnecting your CTS and attempt to start. If the engine starts and runs at high idle, the PCM and the ISC ( idle speed control) are both working normally and that ECT needs to be replaced

Feedback po kayo kung paano naayos. Ginawa namin dinala sa calibration shop, may spring sa injection pump that holds fuel parang pondo yung spring 'flat' na ginawa lang stretch lang spring. sorry hindi ko alam anong tawag doon pinadala ko lang sa driver yun ang pag explain sa akin. it took only a few minutes. simula nun normal na yung sasakyan. thank you

kung sa casa dinala ito, siguradong palit ng mamahaling piyesa ang ginawa...
it is nice to know that there are still shops with practical, "thinking" mechanics.
