SOURCE: E.E.C fuse keeps blowing in 1991 Ford Explorer

if you replaced fuel pump i would look at backward wiring when replaced and i would start at the source of work if your vehicle was working fine before replacement then 9 out of 10 it will be your fuel pump wireing

sometimes when putting wireing back together the connectors have the missing clip and in turn you can turn the wireing in both directions now where positive is touching the ground on both sides of connector kris kross problem check your work this is crucial use a test light to find the right wires where they go

SOURCE: fuel pump relay and fuse in a 92 topaz

It's located in the trunk on the drivers side. You should see a black and yellow sticker below a hole indicating that the fuel pump shut off switch is here. Even if your sticker has worn off, if it's a 92 topaz it most likely will be there in that hole. Shine a flashlight in it and you should see a black unit with a red button on top. Push the button down until it clicks in place. If the button is already down, your problem is something else.

SOURCE: no power at fuel pump chev.S-10 looking for fuel pump relay and fuse

The fuel pump relay is located Under hood, driver side, upper firewall, mounted in relay block.

The fuse is located under the instrument panel to the left of the steering column. The fuse block should be visible from underneath the steering column, near the pedal bracket. If the panel is not visible, check for a removable compartment door or trim panel which may be used on later models to hide the block.

I have a 1992 buick roadmaster..and after driving my car for a while,the fuse to the ecm blows..what could be the problem?


Early 90's GMs have had more than thier share of electrical problems. the problem with your Buick is not unheard of. The most common cause of the ECM fuse blowing is a short to ground in one of the ECM sensor circuits. So check all of the engine sensor connections and the sensors. Pay particular attention to wiring underneath the car. Could be the ECM is faulty, but fairly uncommon for this to be the case.

1993 Buick Roadmaster keeps on blowing fuel pump/ecm in-line 20 amp fuse. Car stalled out in a parking lot, would not start, no fuel. Changed fuel pump, fuel filter, fuel pump relay. Found fuel pump/ecm...


Sorry to say it could also be a faulty ECM. The ecm uses circuit boards to provide grounds to a bunch of components and can short out internally.
Most of those components can fail and cause the same problem by causing a short "thru" the ECM. Things like injectors, O2 sensors, and so on.
I doubt you will find the problem without a book and some test equipment.

1992 Buick Roadmaster no power to fuel pump. New fuel pump and changed the ecm ...please help


Theres a few more checks But i'm sure you checked the fuel pump fuse already ..Use a test light and check to see if the fuel pump relay is getting power from the supply and from the Ignition feed. should be a schematic on the underside of the relay..if no power from the feeds check for a blown or rotted fuseable link or a maxi fuse..good luck

I have a short in the wires for the fuel pump keeps blowing fuses when you move wires connected to the relay just put in a new fuel pump thinking that was the problem. where can i get a wiring diagram to...


The problem may actually be in the fuel pump relay itself. The windings of the relay which create an electromagnetic field when energized, may be shorted and/or creating a high current draw, thus blowing the fuel pump fuse repeatedly.

I hope this helps! :)

Location of the fuel shut off on a 1992 buick lesabre


There is no fuel pump cut off switch on the LeSabre. Check the fuse and relay on the passenger side behind the glove box. There should be 4 black relays. The fuse pump is below this and the pump fuse is number 6. The other thing to keep in mind is the Pass lock system may not be recognizing the ignition key and has disabled the fuel pump from the ECM. Lets start with the fuse and relay first and we'll work on the Pass lock relearn process which takes about 30 min to do. Good luck and keep me posted, be glad to help.

Car will not start


If the starter is good, a bad ignition module or failed fuel pump will produce similar symptoms, i.e. no cranking, nothing happening when you turn the key. Ignition module sits under the distributor cap and is about the size and shape of a cassette tape with 2 female plugs and one male plug. Quick way to check the fuel pump is to put the car in a quiet place like inside the garage. Find a quiet friend to sit behind the wheel and turn the key so the dash lights come on, DO NOT TURN THE KEY FULLY LIKE YOU'RE TRYING TO START. You get down on the ground and listen near the gas tank for the quiet hum of the fuel pump that tells you it is working.
