how to properly diagnose spark or fuel problems
Im a novice here and having problems and need some help. 1993 formula a4 I recently did some bolt ons and a tune and now the car wont fire or run consistently. With my new chip installed the car would cold start but after a drive would not restart. I first thought something was loose in the ecm. After making sure everything was installed correctly I then lost spark. I tried to jump the coil wire and nothing. So I replaced the icm the coil and the opti only bc it was under warranty. The car started, drove it around the yard and it dies again. I checked my chip again and found a slightly bent pin. Straightened it and car started put the car in reverse and it Stalled as if it was out of gas But I can hear my pump running etc. how can I check for fuel pressure or injector issues? After bending a pin have I compromised my ecm....it wasnt that bad.....getting over my head fast plz help....
