Chrysler Repair: engine stalls hot wont restart until it cools down, chrysler sebring lxi, crankshaft pulley


Question
I have a 2000 chrysler sebring lxi 2.5 engine and when it runs at idle for about 15 min it stalls and wont restart no dtc's are present. There's no spark and no fuel from the injectors the fuel pump is priming and the distributor is a reman replacement. I did a tune up all the parts had 100,000 miles on them. I cleaned the throttle body and it ran for about 45 min the iac seems to be operating i unplugged it and the idle changed. I swapped the asd relay when it stalled and still the same thing.

Answer
Hi Jermaine,
It has the symptoms of one of the engine sensors failing after it gets warmed up, and then recovers when it cools. While is it in the stalled state I would suggest that you check the voltage pulsation at the crank and the cam rotational sensors.
They share a common ground wire at pin 43 of the pcm, and then you would attach your voltage probe to either pin 32 (crank, gray/black) or pin 33 (distributor/cam, yellow/tan) sensor. Use fine pins to pierce through the insulation of each wire and attach your probes to those pins. Turn the ignition sitch to the 'run' position. Then use a socket and handle to rotate the crankshaft pulley clockwise by hand. The voltage should oscillate between 5V and 0.3V several times per engine revolution if the sensor is working. If you don't get the pulsation then the sensor has gone bad when 'hot'.

PS Sorry for the delay but I just found your question in the 'pool' to which it had been refered by Kevin.
Please 'rate' my answer, and where you  see the question about a nomination of me to be 'volunteer of the month' consider a 'yes' response. Thank you
