    No fuel pulse at #1 cyl???? ----- 4tec

    I have a 2005 rxt 4tec engine thats not producing a fuel pulse at the #1 injector.
    Wires checked good, ecu check good, injector check good, fuses check good and spark on the #1 cyl good.

    What is the problem? Any one know or have a similer problem.

    Sounds to me like injector drivers in the ECU. There really isnt anything else it can be I dont think. Did you swap injectors with another cylinder? Do you have a noid light set?

    The noid light showed no pulse..... The ecu was replaced with a known working (good) ecu - no change.
