Question about 2001 Nissan Altima

1 Answer

2001 Nissan Altima fuel pump is not receiving electrical power?

I've checked the fuel pump, battery, fuse, and relay. All work fine, but the fuel pumps is still not receiving power to turn it on and pump when installed. I thought initiallly that my alarm is shuting down the fuel pump. I've reset my alarm, but it still will not start up? The fuel filter is 6 months old and the car has worked fine up through last wednesday. What is the solution?

Electrical prblem


There would be a fuel pump fuse, either under dash or under hood. Check that fuse, use the test light to see if fuse has power. If not, then it might be a fusible link or maxi-fuse that feeds the fuse panel. If fuse has power with key on, pull the relay, and use the test light and probe relay terminals, key off. One terminal should be hot at all times. If not, check for power loss between battery and relay terminal-possibly a maxi-fuse or fuse link.
If relay does have power to terminal, quickly check other terminals while someone turns key to on-for about 2 seconds, another terminal should show power-this would be signal from computer to turn the relay on to prime the lines and fuel rail. If you have that, plug relay in and cycle key. Does relay click? If yes, relay is working and problem may be at fuel pump connector. If relay is not working, but you have power to it, and the short signal from computer is there, then check the relay's coil side ground. Computer signals the coil side and the signal goes to ground from relay coil side.
Pull the relay and use a jumper wire from relay's hot terminal to fuel pump terminal-the wire to pump from the relay. If pump comes on, the problem is right there at the relay-either no signal from computer or the relay coil's ground is lost. If pump does not come on, again check connector at pump-that or the wire to pump[ has a problem.

Im trying to find a wiring schematic for my 1990 nissan mainly fuel pump relay to the fuel pump to the fuse under the dash


The fuel pump relay is powered by a 10amp fuse.
The computer relay is powered by a fuseable link connected to the battery.
You might want to check the lines coming from the battery and starter for open circuits.

I have a 95 nissan maxima...i have put new spark plugs, camshaft sensor, 2 crankshaft sensors, electric ignition...and checked the relay plug and fuse that goes to the fuel pump...and something is still...


the fuel pump is toast, use a volt meter or test light to check for power at pump, if receiving power then pump is faulted, if not receiving power follow wire testing at every connection until you find power. once you find power you will most likely find part at fault if not pump

Nissan Altama Starter Relay electrical problems or a fuse?


Double check the battery positive connection wiring carefully as it commonly has connection problems when the battery is changed.

My fuel pump isnt getting any power to it at all and its brand new. My car will turn over but it won't start..HELP..also we've tested the relays and the fuse.


If the fuse and relays are good, then it is most likely a wiring problem.

First using a test light or meter, make sure you have power to the fuse when the ignition is on.
With help from someone, make sure the relay is engaging. This can be done by feel (should be a faint click when engaged) or with a meter.

From there, trace the wiring to the fuel pump.

Xterra car quit running. had no spark @ distributor. replaced crank sensor and got spark. no gas pressure. replaced fuel pump, new one do not work. no power to it. checked fuses/relays, no luck. ran...


the fuel pump fuse is fuse #1 15amp in the inside fuse box ( left side of dash behind fuse box cover ) the fuel pump relay is behind left side of dash ------- cavity #2 & #5 at the relay should have battery voltage in start and run cavity # 3 is the power out to fuel pump and cavity #1 is the ground that is turned on by the on board commputer.

MY 01 Nissan Altima does not want to start.


Sounds like either the fuel pressure regulator or a clogged fuel filter.
