Ok, got a 92 3.9L that likes to play a twisted game. It will run around fine all day, but once or twice a month it will not start back up after a short stop.
If I sit and wait between 2 to 20 minutes it starts and runs FINE. Untill yesterday when it pulled this stunt and stayed dead, I have fire, And Fuel Pressure at the rail, but no fuel goin into the intake.
I was told that the pump may not be delivering the RIGHT amount of pressure, but I have a feeling this has something to do with the computer... oh and the fuse-link under the power dist. box for the ASR has already been replaced... any ideas?
anyone else with a possesed 3.9?!

You know my 92 3.9l 2wd did about the same thing. Ran great never had any problems but every once in a while I would be coming to a stop or slowing down into a turn and it would just die. Let it sit for a second and it would start right back up and it wouldn't repeat the problem for another good period of time, maybe once or twice a month at the most. Strange no idea what caused it and I sold it before I could try to figure it out you might talk to a mechanic well versed in dodge mechanics and see if its a common issue amongst the 92-93 model years or with the 3.9l in general.

Probably not the fuel filter, I replaced the fuel filter in my 92 and it still did it after the fact.

Yup, Fuel filter is less than 600 miles old, ASD relay splice has been replaced and run since.
I got the flash codes, #17 Closed loop temp not reached or engine cold too long, which was set when the temp sending unit was shot, has since been replaced but I think it kicks that code due to the 180 thermo I left in it.. Supposed to reach 193-196 I think..
The other code was #37 Torque converter clutch solenoid CKT or park/neutral switch failure... But wouldn't neutral safety switch cause the ignition not to try at all? As I said, I have good strong starter spin, compression sounds fine, it acts like it wants to hit, and will if you give it a lil gas into the TB so I obviously have timing and fire, just no fuel delivery...
Ok can someone tell me how much pressure I should have at the rail?
And can a standard test light even read the 4Volt injector pulse?
If not how can I test for pulse?
