Is there anything that's in the system other than the fuse or the relay. Like a fusable link that in the system.

No. But if you're having problems with the fuel pump, give me some details and I'll try to help.

I am also having this problem. No ground signal from pin51 on the computer to turn on the fuel pump relay and the auto shut down relay. If I ground this pin pump turns on and will pressure up. Tried a different ECU computer with no joy. Was told that the body control and transmission computers send a go signal to the ECU that takes it out of safe mode to allow fuel flow. Same thing after a crash and airbag deploy or somthing breaking in the transmission.

Looks like I need to find someone with a pre OBD2 scan tool to check the computer. Without specific pin signal data for the ECU it is hard to know what signal is missing. Cam sensor pulses, crank sensor pulses, loop signal from O2 sensors.

I had some stalling and failure to start episodes along with some cruse control and tachometer issues before I ended up with the crank but no start. The only code I had was 54 or cam timing sensor. Have disconnected the negitive battery cable and reset the computer several times although I am not sure if all 3 computers are actually reset. What we need is a USB port and free software so we can hook it up to a regular PC.

ANY IDEAS?
