Man I swear its one thing after another with this one. So I ended up buying a 1996 over the weekend, was told is had a blown head gasket. Clean little 4x4 Jeep with 170k on it. Got the head off, found the #2 piston scorched. I cleaned up the cylinder, stuck another piston it in, put everything back together last night and thought I was home free. Now I'm not getting any fuel at the fuel rail, not hearing the fuel pump come on.

Pretty sure I'm not getting any fire because I threw some ether to it and not even the slightest try of wanting to start, it just cranks and cranks.

Everything to me points to the CPS but I just pulled the Jeep in the garage a few nights ago under its own power so I don't see how that could have gone bad over the weekend? I count 3 grounds on the motor, one on the back by the firewall and the other 2 are by/under the dipstick. Those are in place. Could I have connected the CPS to the wrong connection? At the time it seemed like that was the only male female end that matched but Ill double check when I get home.

Anyone have any ideas? Hate to go buy a CPS and that not be the issue.
 
It sounds silly but CPS fail like that.

Unplug it and plug it back together a few times. Mine did that work one night. Googled that fix on NAXJA and went and tried it. It fired right up. Try it, it could work. I swapped out the CPS later.
 
So when testing the prongs on the cps, reading B to C, my meter just reads OL. However if I swap the leads and put the black one on B and the red on C I get a reading of roughly .970 volts.

Just going by what I read on naxja but I'm suspecting the way I read it first, with red to B and black to C that the sensor is good??
