    repost from DieselClub.org

    I have an Isuzu Fuego at first was just stalling and having a hard time restarting the engine. I was able to take the pickup home but now the engine doesn't start up. Some mechanics that tried to diagnose the problem claims that its the injection pump. My relative is saying that it might be the engine already.

    Does anyone here know of any diesel mechanic willing to service/diagnose my vehicle at home. I reside in Moonwalk in Paranaque.

    na check mo na ba glow plugs?
    mag start ka muna dun, may redondo ba?

    battery...

    ignition...

    troubleshooting 101 muna

    para ma eliminate natin ibang factors at malaman natin ang cause.

    glow plugs are because the engine is already running before it stalls, after that comes the hard starting part. after restarting the engine, I would go a few kilometers before it stalls again.

    battery is ok. meron siya redondo.

    ignition problem once engine stalls. I have already bled the fuel line. Problem ko ngayon, hindi ko na siya ma start.

    Any tips on checking power on the injection pump? All fuses kasi are ok. I have the 4ja1 engine. According to the wheeler's club mechanic walang power daw yun injection pump.

    My dilemma is baka may tama na yun makina, piston ring, sleeve etc.

    Gusto ko sana pa check sa diesel mechanic. So I know my next step, to have it towed to a calibration center or talyer pag engine problem talaga.

    Meron ba may kilala dito na nag home service?

    check mo yung shut off sa injection pump. it might not be opening, may wire there it may be corroded or may tama.

    meron ba ECU ang 4ja1? I'm planning to test the injection pump by directly connecting it to the battery. I haven't really examined the injection pump, is it just a power wire or are there also wires for sensors output?
