2001 Dodge Caravan died warming up in the driveway last weekend. Turned the key and no engine cranking. Lights on the dash all lit and completed internal diagnostics normally. Keyless entry worked and the battery seemed OK. On closer inspection there was no clicking from the starter that would indicate a weak battery, nor were there any Diagnostic Trouble codes (DTC's) set by the computer (PCM) -I have a scan tool. Checked fuses and relays with volt meter in the realy center next to the PCM. By by following the schematic (using a Haynes manual) I was able to supply battery to the starter (the engine cranked just fine) and the fuel pump (it ran).
On further investigation I determined that the PCM was not supplying ground to the Automatic Shutdown Relay, or the Start relay. As the camshaft sensor and/or the crankshaft sensor can tell the PCM to shutdown, I repalced those two items on a long shot to no avail. Had the car towed to a shop I work with and they came to the same conclusion that I did -- the PCM needed replacement.
Called NAPA and they sold reconditioned units for about $170 (with core return) there was a nationwide backorder on them (Don't know why). Found an online outfit All Computer Resources, that had refurb units. The unit was more expensive, but they programmed the VIN and milage in before shipping. I had the unit overnighted to the shop. It arrived the next morning and I had my fingers crossed. The VIN determines the PIN for the passive security system (SKIS code). But, there were no problems. I picked the car up the next day. So far it's running just fine.
PS: if you pick a unit up from the junk yard you will have to get the VIN programmed in before it will run. It might start, but the security system will shut it down. Hope this helps someone.
Testimonial: "sorry for the late response. This worked great. Thanks,"

This sounds like a classic bad connection either at the battery or engine ground. Check and recheck all your connections and be sure they are clean and tight.
