ok so ive been fighting with my 97 dodge neon 2.0L SOHC for while now. and it's been winning so far.
The Symtoms: Its starts right up and runs perfect. after a few minutes it just suddenly dies and then loses spark. now after it cools off for awhile it will start right back up again and do it all over. but it just cranks until then. at first it would run until it was almost completely warm before doing this now it will only run for about 4 minutes before dying. and now it also has to sit way longer as well.
What i've tried: It has a new ignition coil, new cam sensor, new crank sensor, new connector on the crank sensor. It has perfect fuel pressure even after it dies and yes the fuel pump is still working after it dies as well. now after i put the new connector on it wouldnt start at all. I found a thread on a forum saying that one guy pulled the automatic shut down relay and put a jumper wire across and it fixed his problem. so i tried this and it started right up again but died after 4 minutes. i then left the jumper wire in there which in turn killed my battery apperently.
im so stumped on what to even try. it shows symtoms of a bad crank sensor but i already replaced that and it did nothing. and when i replaced the motor with one from a 96 i looked over all the wiring and none of it is damaged. i think my next step will be to try a new computer but i was wondering if you guys had any other ideas i can try.
i miss my gas mileage. my truck only gets 20mpg tops and the neon gets 37 1/2 lol
