    I tried starting my car. I had goten a ballpark injector timming. I tried starting it.

    It went pop pop pop

    Ajusted them again and no mater what i carnt get it to even get it to pop. NO fuel is getting into the cylinders. Ive taken the rail off to look for blockages, but no its perfect.

    When the ecu is on in 'run' i pulled an injector out and pluged it in and it did not humm?

    They are low impendece ones 3.1ohms ive had the cleaned and benched tested all of them came to 390cc/m

    HELP

    and i am getting a HZ out of the plug and about 5v (comes down becuse of pulse withd assuming)

    check if ur fuel pump is pumping fuel get a test light and check while someone is cranking the car.... if theres no power goin to the fuel pump follow the cable back to the ecu and check if there is a good connection in the plug

    so is this after u done a engine swap or just a injectors swap?
    i had similar problem.
    i had to change engine so i use the stock injector that came with the engine
    but it didn't start up.
    i found out it was the injectors were of wrong impedence
    i swapped the injectors back to high impedence which i was suppose to use because of my microtech then it
    starts first go.

    hmmm its just that my ecu is desinged to handle low impendence injectors. And whats really pissing me off is that it did try to start. Now nothing
