I take it the MIL is not on??
This should be throwing a code.
Can you see any damage to the wires going to the pump the whole length .from the circuit opening relay
The MAF is getting the signal from the ECM??
** Check the circuit opening relay that is what powers the fuel pump **
** The part that really sucks is it up behind the steering wheel behind the dash never having had to find mine I am not real sure just where.
Which goes to the circuit opening relay when the contacts close it goes to the fuel pump.
There are Two coils in the circuit opening relay if the run side has burnt out that is why it dies after a few seconds.
Just how are you jumping the fuel pump at the connector??
If you need more help PM me I should be able to help
