Engine Performance problem
1993 GMC Jimmy 6 cyl Four Wheel Drive Automatic
My jimmy has a vortec 4.3 it runs fine for a few miles then stalls and wont start for hours or days. I changed the icm, no help. So I changed the rotor and cap, no help, then coil, no help. So I checked the coil for spark by taking a plug wire and putting a spark plug in it but didnt see any spark. It wont start at all now. Do you know what the problem can be?
