I have checked the fuel pressure and I am at 30-32psi and the voltage going to the pump is at 13.75 volts. Both pressure and voltage were the same when the engine was hot. I have done the screwdriver test to the fuel injectors and they all seem to be working well. I have fresh plugs and wires in it and they are all firing. I have checked my connections to the PCM and everything looks to be in order there. The gas filter is relatively fresh and the inertia switch are in working order as well as the fuel regulator. If you can help i would appreciate it, this oone has me ready for a drink!!!
