I have a 1990 Oldsmobile Delta 88. It has the 3.8 3800 Motor. The other day it was raining out so I started the car up and let it run for about 5 minutes. As I was walking over to the car it shut off. I started it back up and it shut off after about 10 seconds, I started it a third time and it shut right off. Using a small paper clip I jumped the two OBD 1 Pins, the radiator fan kicked on like normal and I was trying to get the codes when the radiator fan started flickering on and off, then the engine light started flickering really fast, and then I noticed the fuel injectors started firing just like the car was running, but the car was off with the Key in the on position. I did manage to quickly get a code 42 which has something to do with the Electronic Spark Timing circuit. I waited a few hours and the car started right up and I have been driving it since then with no major problems as of yet. Has a new Crank Sensor. The car has a slight idle missfire and 4 of the 6 fuel injectors have a skippy feel to them if I put my fingers on them, the other 2 injectors give a solid spray each time. I swapped in a spare ECM and that did nothing to help this issue. I feel like the electrical issue and the missfire are related. I hope I will be able to have some trust in my car again soon. Not sure where to go with this issue, any help I can get would be greatly appreciated.
