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: on a 1991 geo tracker trying to find location of fuel pump relay?

The fuel pump relays are mounted on an "L" bracket underneath the ECM. Both have something to do with the Fuel pump. Be careful not to get it confused with the horn relay it is in the same vicinity (under the dash on the drivers side).

Yes, there is a Fuel Pump Relay. The Relay is located on the firewall just above the left-hand (even cyclinders) valve cover as viewed from the front of the car. There is also fuel pump test lead attached to the harness at the fuel pump relay. Attach a power wire from the battery to the lead and the fuel pump should come on. If fuel pump comes on, the relay could be bad. Also check the fuel filter located under the passenger side of the truck tucked into the frame rail.

I have an 89 Olds 98 Regency. The fuel pump comes on with the key then shuts off less than a second later. Does the fuel pump need to be replaced or is there a relay module that could possibly be the...

The fuel pump will come on then, shut off when the key is placed in the ON position, this is normal. What is not normal, is when the key is turned to start the engine, and the fuel pump does not run when the engine is running at the same time. The initial power up you hear is a prime function that all vehicles have.

Disconnect the fuel line at the fuel filter. Turn the car on for the pump to be on. If you are getting gas pumped out, then your pump is good. If not there's most likely your problem. Then try the line at the engine. Disconnect and see if the gas is making it that far. Your should also be able to hear the pump come on if you open the gas cap and listen while someone turns the key to the on position.

Fuel pump not running. pump is new and i replaced the main relay

Bring the relay back into view and tap it with a screwdriver or something while you try to start it at the same time. If it starts you have another bad relay.

1991 Honda Accord cranks but will not start

I think you should check the air filter or air intake. It seems like it's not gettin and air to start since when you spray the starting fluid it's runs but stop and it stalls. I think that it's the air supply for the car.

Hard start sometimes wont start after fuel pump was replaced

Replace the fuel filter before the pump goes bad, just paid $700 to replace OEM withan aftermarket fuel pump and filter (better than $900 quoted by another shop. Had I changed the filter sooner, may have avoided. Now dealing with a bad intake mfld gsked and old leaking oil cooler lines. Help, GM is killing me!! These vehicles are notorious for various issues.

Good luck
