I have a 92 Accord that I just got done rebuilding the motor on. I had forgotten to secure the ground for the computer at first but figured that out. After I fixed that, I got it starrtted, adjusted the timing and idle, and it ran great for about 3 minutes. I started to runn thru the gears (automatic)to get the fluid moving in the transmission. As soon as I got to D1, the car stopped running and I have not got it to run since. The computer comes on, but the CEL light does not go off. The fuel pump does not come on at all, but when I jump it at the main relay, it works. I tested the main relay and its ok, plus i had replaced it a couple of years ago. I checked the grounds and they are ok. I am at a loss as to where to go next. Could the gear switch cause this issue?
