03 GTX Power to Fuel pump issue
A friend has a 2003 GTX that appears to have an issue getting power to the fuel pump. The candoo
showed occurred faults (not active) of P0231 which states "burnt starter, fuel pump 10a fuse" as well as "fuel pump shorted to ground or open circuit" and P1681 - "burnt information center 1A fuse) and P0463 - "fuel level sensor circuit shorted to 12v or open cicuit"...otherwise the Candoo shows nothing else
He has cleaned and reconnected all the connections of the fuel module, tested the fuel pump itself on the bench (runs), checked and actually replaced all the fuses and nothing. Turns over fine but will not start. When you put the key on the post, you do not hear the pump winding up as with our other 4 tecs. I have a 2002
that shows a fuse in the fuel pump area beside the gas tank but the 2003 manual does not show this so we don't think we are missing a specific fuse for the fuel pump.
Any ideas to check in terms of power getting to the pump?

the fuel pump is turned on by ground in the ecu
I have seen a bad connection in the ecu connector 2 give many different error codes

A note for follow up - found a bent pin in the ecu connection. Machine fired right up then.
