This is OBD 1 NOT 2, I can still read the codes with a jumper key or does it need a deeper scan, if not then there is no codes right now. I went ahead and replaced the control module, ignition pick-up coil and coil, still the same results. I had my son turn the key to on and listen for the pump at the tank. The pump took some time to build up pressure, longer than two seconds. The truck would start, run for a minute thhe pump would shut down like someone turned the key off. Do you think it could be the ECM (on board computer)? Keep in mind I just replaced the pump and it has about 1/4 tank of gas thats about 15 gallons it has a 44 gal tank!
