all relays are located under the hood behind the air filter. pop the top you will see these black square fuse like. my Mazda 3 2004 all 5 of them are the same relay, so you can swap one with another to see it that cures the problem. mark each one before you swap them, so you can put them back in order just in case.good luck
The Fuel Pump Relay is at position 3 in the engine bay relay plate
on the firwall on the driver side there are 3 relays, one is the fuel pump relay
The fuel pump relay switch is the middle relay on the passenger side firewall. there are 3 unmarked relays. the middle one is it.
One of them is the fuel pump relay.
where is fuel pump relay switch on 2003 ford ranger
Turn key on-jumper relay receptacle pin 1 and 3 this will cause the fuel pump to come on-
for me it was over heating(caused by a relay), then loss of coolant, and another reason was because of the fuel pump going bad
There is a relay box between your main fuse box and the air box. Little black number with 3 relays in it. In there is the wiper relay, main relay and the fuel pump relay. The main relay has a large red wire and should be closest to the front of the car. The fuel pump relay should be the middle one.
There are testing procedures for relays and ohm readings but it differs for all makes. The easiest way is to swap out an identical relay on the vehicle and check to see if the pump comes on. I know that on Ford Rangers there are 3 that are the same ECC, fuel pump, and AC. Since I knew that the ac worked I moved the relay over to the fuel pump and got no response still, so I moved it over to the ECC and both it and the fuel pump worked so that told me that the ecc relay was bad and it in turn triggered the fuel pump relay to activate in series.
The fuel pump relay is in the underhood fuse box.Fuse box is on drivers side fender well. The fuel pump relay on my 1997 Olds Bravada is located in the glove box top left side in the back behind a cover. There are 3 relays that are the same and the Fuel Pump relay is the left one of the 3. I replaced mine and that did not fix the problem though. I am going for the new ignition switch. I have power to the relay then I loose it. Good Luck.
There are 3 relays in the glove box. All 3 are behind the plastic cover in the upper left corner of the glove box. The relay to the fuel pump is the one to the far left.
the fuel relay is located on the firewall on the drivers side in a bank of 3 relays its the one closest to passenger side
