I had a 1971 f900 truck , which is a gas engine vehicle, that we used in the harvesting of silage and grain. It had a 534 cid engine and had a mechanical fuel pump which does not require a fuel pump relay. That said, someone could have added an electric pump which could use a relay. Follow the fuel line from the carburetor to the tank. A mechanical pump will be connected to the engine. An electric pump would be inline or in the fuel tank.

1971 buick 455 fuel pump diagram


The pump has an inlet and an outlet. To find the inlet (coming from the tank), hold your finger over the openings and have someone crank the engine over. The fitting that has suction on it is the inlet-hose from tank goes there. The hose to the carburetor goes onto the pump's outlet fitting (with clamps).

Car will turn over but won't start. Through the


No noise from fuel pump when you turn over the car .First thing get voltage at fuel pump relay checked, is there 12 volt to the relay.If no, then problem is again the relay.--------- To reconfirm the problem, try other test, that is remove the relay and by pass the relay terminals with a jumper wire .Then with 12 volt external battery give power to fuel pump connector and see, if the fuel pump starts, then its clear that fuel pump relay is faulty.----------- Also other problem can be fuel pump inertia switch.If the inertia switch is faulty then also fuel pump will not start.-------- The fuel pump relay on a 1995 Ford Explorer is in the power distribution
box, in the engine compartment, driver's side near the firewall.----------
The fuel pump inertia switch is in the right front passenger area
it is below the dash but above the carpet in the right hand corner.--------
Its a push button type inertia switch.
--------
Fuel Pump Activation
When ignition switch is turned to START position, PCM operates fuel pump relay to provide fuel for starting engine. PCM senses engine speed and shuts off fuel pump by opening ground circuit to fuel pump relay when engine stops or engine speed drops to less than 120 RPM. When ignition switch is in ON position, EEC power relay is energized (contacts closed). Power is provided to fuel pump relay and timer in PCM. Fuel pump receives power through fuel pump relay contacts.
Inertia Fuel Shutoff (IFS) Switch
All models use an electrical interrupt switch in fuel system. During a collision or vehicle rollover, electrical contacts within inertia switch open, shutting off fuel supply to electric fuel pump. Fuel supply is interrupted even when engine is running.
A reset button is located on switch assembly. If electrical circuit trips, vehicle will not restart until switch is reset. Fuel system should be inspected before resetting switch.
IFS switch is located under instrument panel, near right side of transmission hump.
----------- If the fuel pump relay, the inertia switch and fuel pump all checked ok, and fuel pump is working with direct 12 volt source to fuel pump.Then problem relates to computer.The computer (power control module, PCM) is faulty and has to be replaced.--------- This will help.Thanks.Helpmech.

It sounds like an ignition module failure or the ignition coil is overheating. If it is fuel injected, a fuel pump relay could be the problem

Both fuel pump relays run hot. I have replaced both of them. The truck started and ran for about 30 minutes then quit. I replaced the relays and it ran for a few minutes and quit again.


You could have a bad fuel pump relay switch. The fuel pumpmag-glass_10x10.gif relay switch gets the fuel pump running in the vehicle during the start cycle. The terms fuel pump relay and fuel pump relay switch are used interchangeably. The fuel pump relay begins its job when the automobile operator turns to the ignition on, but before the motor is actually running. At that point, the fuel pump relay in some cars sends a signal to the ignition switch, which in turn sends a signal to the fuel pump to turn on. Others fuel pump relays have actual circuitry inside of them that receive the ignition signal and directly signal the fuel pump to engage.

Have a great day!
