Can I test the CPS or is it a replace? So, back to my original thought. If I turn the key on and the CPS is bad, will it not let the fuel pump energize?Yep I forgot about the crankshaft position sensor. If that's no good, it can't tell the computer to allow spark and fuel pump activation. And it's something else that doesn't go out all at once.
Had the CPS go bad on my Burb a couple years ago. No crank, no start. Nada. Replaced it, got cranking, but still no fire up and start. Replaced the rotor. Fired right up!
I was also beginning to have passlock issues intermittently, but your truck is old enough to not have passlock. Lucky you! It's a pita when your truck thinks you're trying to steal it.....
I have also heard about the humidity problem with some vortec distributors. Fortunately not experienced it personally, but I know my cap and rotor are good. When I got this Burb, it had been having carbon tracking in the cap. Eventually broke the nose off the starter and ruined the flywheel, since it was firing 2 cylinders at once. Not a good idea while starting (or really anytime).
I just cleaned and dielectric greased the battery connections and it would still start. Okay, so I let it sit for a day now it won't start ...again. The CPS issue doesn't make sense to me, but I have no clue about that...
