05 1500, 4.3, no spark

Postby chevydude123 [OP] » Mar 07 2013, 3:36am

Have an 05 silverado 1500, 4wd, 4.3, 5 speed. Started with no spark. this thing as it sits has new: Plugs, wires, distributor, cap, rotor, coil, ICM, and now crank sensor. At the coil ive got 12v on the pink wire, and have ground pulse from signal wire. All of these ignition components are OEM replacement. Has not run since replacing all parts for the final time. Distributor is not 180 out. out of ideas here. any help is greatly appreciated. The truck turns over all day long, but cant seem to get a spark out of it (checking from coil wire, not spark plug wires).

Are you sure the rotor is turning? My line of thinking is maybe the camshaft gear is broken or some other fluke. Have you checked the system for codes or had a scanner attached to the computer to check the live data?
