Where is the fuel pump relay located in a Nissan?
– IPDM E/R (Intelligent Power Distribution Module Engine Room) integrates the relay box and fuse block which were originally placed in engine compartment.
What happens if the fuel pump relay fails?
The fuel pump relay is part of a power module under the hood. In that module are several relays but the bad news is they are not serviceable as the entire module has to be replaced if the fuel pump relay has failed.
What to do if your fuel pump wont turn on?
First check fuse 48, a 15 amp, in the under-hood fuse box. Next, remove the fuel pump relay from that box and check for voltage on the terminals in the socket. Two of them must have 12 volts when the ignition switch is on. If that’s what you find, try swapping that relay with a different one like it, then see if the pump turns on.
Why did my Nissan truck not start up?
My truck would not start, I had Nissan diagnose it and was told that the the fuel pump was bad. I pulled the fuel pump and hooked the new pump to the wiring harness and it is not doing anything. Usually, I thought, that after the key was turned on, the fuel pump would engage. This is not happening. I checked the fuse, fuse is ok.

How can I tell if my fuel pump relay is faulty?
2. Engine does not start. Another symptom of a faulty fuel pump relay is an engine that does not start. If the fuel pump relay fails the fuel pump will be left without power. The engine may still crank when the key is turned, however it will not be able to start due to lack of fuel.

How long does it take to clean a Nissan fuel injector?
Put the rest of the Sea Foam in the gas tank and a few ounces in the oil. Expect to see smoke when you start the Nissan. You will need to change your oil within 100 miles. Visit your favorite mechanic if the fuel injector cleaner doesn’t work satisfactorily. Your mechanic will use a special tool/pump to perform a fuel injector and rail flush.

Can a fuel pump run with the ignition switch on?
The fuel pump had better not run with just the ignition switch turned on. To do so would pose a serious fire hazard if a fuel line got ruptured in a crash. The pump should only run for one or two seconds after you turn on the ignition switch to insure pressure is up for starting.
Can a Nissan Titan fuel pump go bad?
Nissan Titans are usually very tough and reliable trucks. However, their fuel pumps have a tendency of going bad and becoming plugged with residue and other debris. But rather than pay for labor charges at an auto shop, you can easily replace the fuel pump yourself by following these step-by-step instructions.
Where is the fuel pump relay on a Honda Accord?
The fuel pump relay is in the IPDM right rear of the engine compartment. Check the diagrams below. The fuel pump had better not run with just the ignition switch turned on.
Where is the fuel pump fuse box located?
The engine’s or the dashboard fuse box is usually a long black box containing a fuel pump relay and various other fuses and relays. For different vehicles, the fuel pump relays can be located in different places.
What happens when the fuel pump relay goes bad?
If the fuel pump relay suddenly fails, it will light up the check engine light and store a trouble code on the fuel pressure. The fuel pump relay going bad can affect the fuel pump’s power and affect fuel delivery to the engine.
Where is the fuel pump fuse on a Nissan Titan?
Open the IPDM and find the fuel pump fuse, which is the seventh fuse from the passenger’s side, in the top row of fuses. Pull this fuse with a slight wiggling motion to remove it. Set the fuse in a secure location for future re-installation.
How to check the fuel pressure in a 2006 Nissan Titan?
Guide the adapter through the hole in the disconnect tool, then press the tool upward and hold it. Press the adapter into the fuel supply hose as far as it will go, then release the disconnect tool to lock it into place. Tug lightly on the adapter to check that there is a good connection.
How many volts does a fuel pump relay need?
First check fuse 48, a 15 amp, in the under-hood fuse box. Next, remove the fuel pump relay from that box and check for voltage on the terminals in the socket. Two of them must have 12 volts when the ignition switch is on.

Is there power going to the fuel pump?
Yes, power flows through the fuel pump relay. 1. Remove the fuel pump relay. 2. Check the relay socket for the ONLY terminal that faces differently from the other three. That is terminal #5 and feeds the load (fuel pump). You can double-verify the terminal number by checking it from underneath the relay. 3.
Why is my fuel pump not getting IGN on?
If the ECU doesn’t respond with a ground, and it is also missing on ECU pin #8, then perhaps it is not getting the IGN ON signal on ECU pin #38. If the ECU is getting the IGN ON but doesn’t respond with a ground for the fuel pump relay then it could only be either a bad ECU ground or the ECU itself.
What should crank speed be for fuel pump?
A good crank-to-start speed is about 300 rpm. Besides the rpm, another section of the CMP tells the ECU the relationship of TDC for each piston. That is how the ECU knows when to energize the ignition power transistor and fire each fuel injector.
How do you check fuel pump terminal number?
