I believe my shop book says 50-52psi and when it ran rough my gauge showed 50psi. Could I possibly have a bad crank or cam position sensor? No codes other than the p0001 relating back to the pressure regulator which is new. thanks again
The main problem now is I have to jump the b1 and a3 to power the fuel pump. Thats the only way I was able to develop the 45psi. It developed the pressure immediatly with the jumper. Without the jumper and fuel relay reinstalled, I can turn the key on, pump runs for about 2 seconds and stops and no power to it while cranking. I can do this several times and the pump runs for 2 seconds and stops. I thought the cranking energized the a3 pin?? I don't know but it seems I have a bad ground or I just don't know right now. Any more ideas are appreciated.
Here is good reading from my car program that tell you how the system works when it comes to fuel and ignition as far as starting and energizing the fuel pump relay. I can not get a good copy of the schematic of the system on my printer from this program, but I will look at another program and post it if I can.
Have you check with a voltmeter at the PCM port#3 for voltage when you are cranking it? Don't know what the exact voltage will be, probably 12 volts. If there is voltage then you have wire problems to the relay.
Did you look around on the Ignition control module for bad ground, broken wires, corrosion etc.?
Just throwing things out. Will it still start now , but running rough, or not at all now.
