Nissan Repair Questions? Ask a Mechanic for Answers ASAP
Hello and thank you for your question!My name is ***** ***** I will be assisting you with your question today.
Which engine do you have in this?Do you have a test light or volt meter?
Ok, I am sending you a diagram of the fuel pump relay. It's located in the IPDM, the large fuse and relay center under the hood. If it's possible, check and see if you can feel it click while someone else cranks the engine.
Please try this and let me know. If you aren't cranking the engine you will only get power there for about 2 seconds.
Do you not see the link that says capture.PNG at the end of it?
HERE is the diagram
I am really not sure why you can't see the diagram, but I didn't really suggest anything that didn't include the relay, so honestly, I am not sure HOW you tried what I suggested if you don't know where the relay is?
The fuse, the computer in the IPDM that turns the relay on, the wiring from the IPDM to the fuel pump and the security system.
Check fuse #50 in this diagram in the IPDM, make sure it's got power with the key on
When you crank the engine, is the security light on solid or flashing? This should be up by the defrost grid on the dashboard driver side I believe or in the instrument cluster.
Ok, again someone has to be cranking the engine when you do this next test.
You have to check the power wire for the fuel pump coming out of the IPDM.
This is a black/yellow stripped wire coming out of the terminal.
I am sending you another diagram of the IPDM and highlighted the wire # for you to check. The connector will be located right where it shows the arrow coming out of the diagram.
Yes, it should be 12 or battery voltage. This means the ECM is not turning on the fuel pump relay.
check the black/orange stripped wire on #40. It should have battery voltage until you turn the key on, to run or start, then the voltage should go away. If the voltage doesn't drop the ecm is no good. if the voltage does drop, then the relay is no good and you will have to replace the IPDM
If the power drops when you turn the key on, it means the relay is bad.
With these you can't just service the relay, you have to replace the whole IPDM
It's plug and play, doesn't require any programming or anything. But it does mean the signal is going to the relay from the ECM, so the computer is good, fuse box isn't.
You could try swapping it with the fog light relay and see if it resolves it, but again it's not made to just change the relay so it may not work.
