Fuel pump or fuel pump regulator?
Car will not keep running.

Id say, since the fuel pumps fail often with age. Seeing the current mileage on the car, as a preventative repair, I would replace the fuel pump either way.

Woops Sorry...

I found a blown 20Amp fuse in the passenger side fuse panel for the Electric Fuel Pump.

After testing it with my meter there is a direct short in this circuit that will continue blowing fuses.

I measured across the connector of the fuel pump in the tank and it measured 0 ohms which I assumed was a shorted fuel pump.

I just replaced the fuel pump with a new one and have the same results.

Now I am finally thinking it may be the fuel pump control unit module that is mounted with a big pigtail connector next to the fuel pump.

Any help or advice would be appreciated.
