Engine Performance problem
1989 Ford F250 V8 Four Wheel Drive Manual 166k miles
i have changed out both internal fuel pumps also the one on the rail and the filter. i have also tried 3 fuel pumps relays. when i bypass the relay it runs fine but when i put the 3rd relay in it wont start acting as if it doesnt have any fuel. does any one know what this issue is and how to fix it
