Question about GMC K1500
Truck has new 350 crate engine, with mostly new everything except egr, ecm, and sfi w/ pressure reg.!!! just starting to break it in and truck stalled after going a few miles, started back up but was really rough running and sputtering. it died again and would not start, towed it home and after sitting for 2 hours it started but was rich, and codes read cam and crank sensors, i believe them to be false but why i do not know.. could it be my ecm or just a false reading due to sputtering from richness? also is it possible to stall out from richness? and since everything points to vaccuum, fuel press reg, or injectors im probably going to due upper intake again and replace injection assembly but im curious about the stalling? please any info would help
Hi there,first of all you must synch the cam/crank sensors. To do this put the engine on top dead center remove the distributor cap and look very closely at the dist housing there will be a 6 mark and an 8 mark loosen distributor and rotate untill the rotor points directly at the 8. The marks are small so get a light and look closely.Clear codes and restart. Is vehicle still running rich?
