SOURCE: Looking for the location of the fuel pump relay on

Fuel pump operation is controlled by the fuel pump relay, located in the relay center.


The electrical protection devices are located in the convenience center, which is a swing down unit located under the instrument panel. All units are serviced by plug-in replacements.

SOURCE: WHERE IS THE FUEL PUMP

Am working on the same problem. Have narrowed it down to a couple of things. The primer curcuit on my '88 is not work off the computer it will not prime the fuel system. Have found away around that by putting in a new relay off the starter line. The main problem though is that the check valve in the fuel pump is shot and allows all the fuel to drain back into the tank. It takes too much time to get the fuel preasure up if the fuel system is completely empty. Am going to replace the fuel pump and see what happens. The fuel pump relay is located under the glove box, have not found diagram map of the relays there, there are 10 there. If you need a wiring diagram for your car, go to autozone, can print off a wiring diagram there. Good luck.

Where is the fuel pump relay located on a 1996 Chevy S 10 pickup 4.3L It's not in the fuse box under the hood because there isn't one can somebody help
The majority of fuel-pump relay units are found beneath the dashboard, near the steering wheel. In certain circumstances, the unit is positioned near the engine's firewall or in the location where the steering column is attached. The fuel pump relay's end is usually at the center of the floorboard, under the carpet in the front area of the passenger or driver's side footwell. The fuel pump relays can be found in a variety of locations depending on the vehicle.

Where is the fuel pump on a 76 eldorado
Yours is a mechanical (rather than electrical) fuel pump.

Look at this picture:

http://www.therodshop.com/images/cadillaceldorado/eldoenginenofenders.jpg

Just to the right (in the above picture) of the crankshaft pulley (harmonic dampener) is the fuel pump (flat black body, silver top), and to the left of the steering box.

!988 Jeep Cherokee MPI fuel pressure problem. New everything on/in the fuel system. Can only make it run with a jumper wire from the fuel pump to the battery. Any ideas?
Have you checked the fuel pump relay. If you haven't locate the relay and jump out pins 30 and 87 (there should be a diagram on the relay or if you look at the bottom of it, the pins should be numbered, jump out the corresponding sockets in the relay housing). If the fuel pump turns on when you do that you've verified the power feed is good and the wires to the fuel pump are good. Now with a digital multimeter check that there is battery + on pin 85 or 86. If that checks out, when cranking make sure there is a good ground on the opposite pin (if pin 85 had + on it, pin 86 should have a ground). If all that checks out you can suspect the relay is faulty.

Engine turns over,but no fuel pressure at relief valve.
Check the fuse to the fuel pump.
The issue is repeated blowing of the fuel pump fuse. This occurs randomly and without warning, normally when medium to high throttle is applied. Generally the RPM's will fluctuate briefly before the fuse blows, which cuts off ALL power to the vehicle.
Especially dangerous on a highway! The first mechanic found a TSB related to the fuel pump resistor, and its default location in the wheel well can cause premature corrosion. Replaced it and relocated as per the TSB.
You can bypass the resistor, it's simple and free. You bend pin 85 on the fuel pump relay #15, in your engine bay fuse and relay box. Good luck and keep me posted, at worst ti's going to be a bad fuel pump and your going to have to drop the gas tank to replace the fuel pump. When you bend the #85 pin from the relay, will set the fuel pump on high mode bypassing the resistor.

1976 cadillac eldorado won't start (cranks)
I have had the same problem, the relays inside the ECU are weak when the pump is worn, need to be replaced or used as a steering-signal for an external relay for fuel pumpS, there are two pumps. Also the MAP sensor probably are dried out and need to be replaced, its the small box with the black air hose to it.
