The fuel pressure guage is to the fuel rail, I turned the key to the on position and the gauge reads 50psi.
i would go to the ecm connector and backprobe the injector circuits and see if they have power one quick check to see if the ecm is powered up is cycle the key to the run position and see if the check engine lights up it should come on for a couple of seconds and go out if it does a bulb check you know the ecm is powered up
I replaced the ecm, cam shaft position sensor et the3 crank position sensor. I even have compression on all cylenders. just in case it jumped time. I checked the timing its all on just wont start buck or shift.M
