A31 Fuel Pump Relay?

[o0o]

i just checked the ecu codes for fun...it says fuelpump relay^^

if the relay is f**ked up car won't run i know,...but mine is still running

or is it possible that the relay is "half" f**ked?^^

is that the relay?(in the trunk between the taillights?)

sry for that dumb question guys

Yep that the one. It's Nissan universal so replace it with one with the same numbers and plug type.

[o0o]

is it possible that the ecu has a problem cause the car still runs and relay is working...or could the ecu say f**ked up relay before it will f**k up?^^

i gonna get a new relay the next days but i just don't understand this here

sombody an idea?

Some of the relays near the fuse cluster are the exact same plug type and numbers...should be for headlights / tail lights, etc,....ie not neccesary to run.

Swap the over see if that works.

Possible that the ECU is the problem....reset the ECU (clear stored codes) and see if the code returns.

What exactly is the problem and how did you test the relay?

Diagnosing the relay is pretty simple.

Turn the igniton on, if the fuel pump primes then it's doing the first half of its job,

Flick the starter motor over a couple of turns, if the fuel pump primes again, then it's doing the other half.

If it's not priming fuel, and the relay IS working fine (or you test out another relay and it still isn't pumping fuel), then you could have a short on your fuel cradle ('sender'), on the tank, or somewhere on the loom going to the relay.

actually there is no problem,...it was just i had nothing to do lol

i checked the ecu for some errorcodes and hoped for no errors^^

but then came error for the the pump relay...

i did what you said and exchanged the relay with a another from under the hood it works fine, with the new relay no errorcode...today i switched the old relay back in its old position and checked errorcodes again and now no error with the original relay?

its getting confusing

as far the car runs without problems its ok for me:D

@btw big thx on nic...you already helped me on alot problems now
