Hi , Scotty Kilmer, big fan here ! 

I have a 1991 Chevy Cavalier 3.1 V6 with 137,234 miles on it(Automatic). While starting it one day, the car would immediately turn off. I then noticed if I pressed the accelerator while trying to start it on, the car would turn on and I would be able to drive it. Yet my car would sometimes just stall at a red light or while making a turn. One day while driving on the highway the car stalled out. I tried starting it again by accelerating but it only caused the engine to flood a bit. I changed the fuel injectors , the fuel rail and put everything back together and the car was able to start again but it would still stall. It was shaky. I went to check the fuses and for some reason I took off the fuse to the ECM and put it back in and the car was running smoother and more stable. It was able to run fine without a problem for a week. Until one day while warming up the car, the check engine light came on and it died . The codes I read on it were 23 and 45. I put in a new oxygen sensor but the problem was still there. I decided to take the fuse of the ecm and put it back on again and miraculously code 23 was not being read anymore. I was able to drive the car again. Drove it for a few days. Yet now the car won’t start, the starter workers and the battery is fine. Now it only reads code 45. The car still has a life to it, please help me Scotty Kilmer, you are the best!!
