My engine died again, and again, and.......then it ran fine. The only code I got was a 320 "no crank ref signal at pcm".

Crank sensor is new. New pcm, all pin connectors tightened up, new ign, new IAC.

We've had this problem with it dying before, and thought we caught it with the pcm connectors being tightened.

I replaced the cam sensor and no problems, for now.

Can this cam sensor kick out at 320 code?

 

Did you reset the PCM correctly? https://dodgeforum.com/forum/1st-gen...ine-light.html

 

Adding to what hydra said, also I like to let it sit with the Neg cable off the battery for about 30 minutes with the headlight switch to ON. Make absolutely sure you reset that PCM or it will give you hell with problems you can't figure out.

 

i definitely agree w/ resetting all the electrical systems as described above

 

I did that too. But I didn't turn any lights on. Just unplugged battery.

What is odd- is that it was just dying. Every now and then I'd get a 320 code. I'm thinking that it is just a residual reading from the engine dying. I've replaced the crank sensor twice, 2 new pcm's as well (first new one gave me a 601 code which happens with replacements).

After we let it sit for 30 min it ran fine and I drove it to the parts store and replaced the cam sensor, since it seems to be so closely related to the crank sensor.

It still hasn't died again after the cam sensor was replaced. It could just be coincidental though. I took every pcm connector apart and squeezed the connectors tighter as well (this was all done BEFORE the engine dying, except the cam sensor)
