I cannot find my fuel pump relay location. Also, does my car have a fuel pump reset switch?

I still can't find it. I don't understand those diagrams. Is it inside the car or under the hood?

Hello, I'm Danny.

The fuel pump relay is located in the IPDM (intelligent power distribution module) which is located under the hood on the left side near the strut tower. I've attached a picture below. Hope this helps and thanks again for using 2CarPros.

Hello,

The relay is located in your vehicle's Intelligent Power Distribution Module (IPDM) which is located on the right front of the engine compartment, right behind the headlight. In the diagrams down below I have included diagrams for the location of the IPDM and a diagram with the fuse and relay locations in the module itself. Here is a link for how to test a relay, if needed:

https://www.2carpros.com/articles/how-to-check-an-electrical-relay-and-wiring-control-circuit

Please go through these guides and get back to us with what you are able to find out.

Thanks,
Alex

I have looked all over the engine to find the relay location. I located two different fuse boxes under the hood and none of them are where the fuel pump relay is. Even looked under steering wheel found some fuses there but no relay. Please help I have no idea where it could be. And yes I looked through YouTube and Google images already and no help.

Good afternoon,

Can you hear the pump after replacing the relay?

There should be 2 powers to the relay with the key on. One is fused control and one is powered by the ECM relay.

Can you feel the relay energize when you turn on the key?

My car had stopped working. I charged the battery got it going for three days, it stopped working again. I tried to charge the battery, but it would not hold a charge. I purchased a new batery and it still had a hard time starting the car. I gave it a good kick of gas and it turned on. Tested the starter and alternator no problem there, service light went off. The car did good for a week and now will not start again. I look online and was given several possibilities of what it could be, spark plugs, fuel pump, or head gasket. Here is what happens wen I try to start car; It sounds like it wants to kick over all lights and stereo work fine, the battery is only a week old. After about the third try of starting car it smells like gas, I could be flooding it. A friend said it could be valve cover leaking oil to spark plugs, but really I feel like we are playing a guessing game as to what is wrong with it and I have no idea what to fix. The service light never turned back on so I have no way of checking it. Can you please help me figure this out? Thank you.

Hey JHRNDZ,

It sounds like the ignition relay has gone out and not giving the ignition coil a signal that why you smell the fuel from the injectors, here is a diagram on its location, test or replace it and get back to us please.

Here is a link for the testing

Changed the fuel pump recently, but now I have to change the fuel pump relay. I bought a Duralast relay and I do not know where the location of the fuel pump relay is to put it in. The car is the SE-R model.

I bought a new fuel pump relay but can't find where it is located. Can you please send a picture of where it is located at? I bought the book but it's not helping. My car will crank over, but it's not wanting to fire. It will just crank over and crank over. What do you think it might be?

Good morning,

The relay is in the under hood fuse block. I attached the location for you.

https://www.2carpros.com/articles/car-cranks-but-wont-start

Can you hear the pump run when you turn the key on? It should run for 2 seconds and shut off.

https://www.2carpros.com/articles/how-to-check-fuel-system-pressure-and-regulator

Did you check for spark? Crank the engine and see if the tachometer moves up a little while cranking. That will tell me if the crank sensor is working.

I got a 2003 Nissan altima with a 3.5 engine, it has 125k on it. The car will turn over but won't start, I notice that there's no fuel going to the fuel rail, (I disconnect the fuel line going to the fuel rail) The 10 amp fuse in the engine compartment next to the coolant recovery is not blown, I look for a fuel pump relay but I couldn't find one the question for you the experts where do I go next to find the problem. Thanks OKC man

Hi Martin0514, Welcome to 2carpros

The FP Relay is in the intelligent power distribution module in the right front engine compartment. Check fuse no.32 15amp in the IPDM Do this find the fuel pump connector and power the black and yellow wire from the battery this will cause the fuel pump to come on.
