I have a 1989 Toyota pickup. 4WD, 4cylinder 22re. I recently swapped the motor, it started up fine but then once it was warmed up it would run rough and idle funny. We determined that it was the cold start injector timing switch not shutting off when the truck was warm. We rigged it so that once the truck was warm we took the green and black wire of the cold start timing switch and twisted them together to shut off the cold start. The truck ran perfectly fine after that. The next morning I tried to start my truck and just continually cranked but wouldnt turn over. We did some research and messing around with things and found the only way to start the truck was to manually work the fuel pump by jumping the terminals (fp and b+) in the box under the hood while spraying starter fluid in the intake tube for about 10 seconds.. After doing this the truck starts up and runs perfect. Any ideas why it isnt starting up on it's own?
