i pulled out the CPS today i got from my local chrysler dealer 3 days ago,it tested bad!!,what the H is goin on ???,i did not test it before install,guess i should have?looked around and found one i had replaced a year or so ago,it tested ok,put it in went for a drive,everything ok!!,i also looked over the wiring at the back on the drivers side,some of the injector wires had some cracking in them,so i applied some liquid tape (ever hear of that?)i also changed the ecm back to a used one i had,im getting really gun shy about getting more than a block away from the shop!!!

,2 of the wires hook to the auto shutdown relay and the fuel pump relay, Did you change this auto shutdown relay or swap it with another relay?

Hoping you had found something. Going to look at a '94 in the morning that has an "electrical" problem. Tim

i put in a new mopar CPS today and took the truck to a shop thats said to be good at fixing things,checked the old CPS and sure enough it showed bad after 3 days???????,he said it might be 2 weeks,just about has to be a shorted wire or a corroded connection somewhere

i talked to a long time mopar tech today,he suggested that the CPS might be touching the flexplate/flywheel causing a transfer of fine metal shavings causing a short?,also said to double check the dist under the cam sensor to see if the wheel on the main shaft was tight,and a slight possibility that the flexplate was cracked?,tho he said it would make a BIG racket,which its not!,so i might have to shim the CPS just a little bit ????

I've never had to shim one of them. There is plenty of room to pull it up a little bit.

How can he "talk" to the PCM with OBD1? All the scan tool can do is read the code(s) on OBD1, right? No data stream or other info available? Tim

i m,ay have used the wrong wording,he said something like he couldn't get anything from the ecm,i dont remember the exact phrase,it just seems like if the ecm shows dead there must be a bad connection,corroded wire,or something overheated?,after it sets for a few minutes it will start and drive,it never shows a check engine light??

went to get it today,guy said he found a loose correded connector in the ecm plug,i drove it about 10 miles and it died!,waited a couple minutes and it restarted like always,took it back to him for more work?,after all this i dont now think its the crank sensor,the ones i took out tested ok when not testing them on a metal top bench!!!!
