Fuel Pump Troubles
I have a "90 Big Bronco 302
I came home from work the other nite and as I was turning into my Driveway it just quit
Tried to restart but wouldn't fire up
When I turned on the Key I didn't hear the fuel pump running as I usually can .
My first thought was Fuel pump relay ,Replaced it no help
next I tested Fuel pump itself Works fine when hard wired to Battery
Just not getting any power to fuel pump while in vehicle .
I also checked the inertia switch.
What else should I try ?
I tried to pull codes using Check engine light but it wouldn't give me any codes,didn't even sound like it ran a test (heard no tell tale relay clicking or anything)
Is it possible to just heard wire the pump to the battery with a dash mounted switch ?

Juggalo,
Welcome to FTE and the Big Bronco Forum. We will endeavor to get you the most accurate information we can muster.
You may have lost a relay just not the fuel pump relay. Sounds more like you have lost the EEC power relay. If it fails the fuel pump relay doesn't work either.
