Question
Jtreamer
Hello! I have a GMC sierra 1500 2wd with the Vortec 4.3 in it. The truck has no spark. I pulled the wire that powers the coil and tested it with a test light and it has no power going to it ( I did do this with the key in the on position.) I checked all the fuses and all of them seem good. I have replaced the ignition control module, ignition switch, distributor cap and rotor, and crankshaft position sensor and the coil is new. I checked the wires at the plug in and they are not frayed or anything. The coil is still not getting any power. There is a p0335 code which seems to be a crankshaft position sensor malfunction but like I said I replaced it and I checked to see if there is power going to the crank sensor with a test light and there was. I am out of idea's, if anyone can help that would be great! Thank you!
