06 LTR no fuel pump ground
Ok I give it all at once so everyone has all the Info to begin with.
06 ltr450 got it a while back, it had dropped a valve, so got a used head of a running LTR, a replacement cylinder with a he high compression piston, and new top end gasket set.
Put it all back together, timed it (several times now due to it still not running correct) so now I can get it to start if I give it a tad bit of throttle, but runs like total crap and will not start or idle on its own.
I have checked the valve clearance, I am getting fuel to the injector if I ground the pump manually, the injector is opening, everything I have checked seems to be fine or within spec.
My main question is could the ECU be bad and ONLY not grounding the fuel pump but everything else works, what else should I check?
