Electrical problem
1992 GMC Safari 6 cyl All Wheel Drive Automatic
4.3 vortec, CPFI, Truck ran like crap for a few days then wouldn't start for a day then it did, now won't start at all unless you prime it and will run for a few seconds untill gas is burnt up.
strong spark,
Fuel pressure ok,
12 volts at injector harness with ignition on
I believe this year of 4.3 does not have a CKP as I don't see one close to the harmonic balancer. Is the injector pulse generated from the camshaft position sensor only? Would this be the problem or the ECM or something I am missing altogether?
Is the camshaft position sensor part of the ignition module located inside the distributer?
