    LS 376/525 Crate Engine will not start

    I bought a GMPP Crate package and it will not start? On the off chance could someone point in the right dirfection as I have checked most things with no results.

    Man that's an open ended question. You might try posting in the gen4 section since thats more focused on your engine. I dont think that a ton of people read this particular forujm.

    If you're using the crate motor and the electronics package that was built for it and if that doesn't start your issue isn't the tune so you may be better off working with GMPP or posting on one of the traditional car forums. Good luck!

    Does it crank, and not start?
    Is the MAF sensor pointing in the correct direction? I stuck one on a dyno before and didn't pay attention and someone put the MAF tube in backwards and the MAF was pointing the wrong way. Engine would not start at all.

    Yes radrace19 the maf is in the right way. Have 60psi at the rail waiting, power at injectors and coils, rpm of 160 on crank, 11.5 volts on crank, no voltage drop at either coils or injectors on crank, no codes, I am at a loss.
