92 Lesabre cuts out

IF the fuel pump is under spec at all, I wouldn't trust the pump. But here is the thing with the problems that I see: Temperature is a factor. Correct? PRoblem will stop, temporarily if the ignition is shut off and then restarted. Correct. PRoblem will happen after you start moving, meaning adjustments are being made by the computer only after getting inputs from the data stream. Correct?

HEre is my suggestion: Access the pcm, start the engine, while running, gently tap on the pcm and see if anything abnormal happens. Don't tap aggressively so that a problem happens becasue of the tapping however. I am most suspicious of the pcm. No codes, and abnormal adjustments.

Alos check the red wire from the alternator for any damage as well as the wires and connoctors from the crank sensor to the ignition module for chafing. Look carefully.

Vehicularly illiterate! :Lol:

Yes, one in the same. If the pcm (ecm) =computer is bad, it may not set codes. Definitley check the wires-connections I mentioned first. Look for any bare spots, green spots, burnt or overheated wires.

Take a look behind the glove box or in that area under the dash.
