Fuel Pump Problem?

[MFX]

Hey guys,

I have an R33 GTSt. Today while driving I was putting my foot down bit, the car just started to come on boost and take off, when the car made a popping noise and just died there. It sounded to me a bit like a cooler pipe blowing off, but my car is running an EMS and will still run with a popped off cooler pipe (checked them anyway and they are all fine).

After a couple of times trying to re-start the car, it would start and idle, but if you touched the thottle at all it would just die.

When going to start the car I noticed I could not hear the fuel pump (which is still the factrory pump).

I pulled the pump out of the tank and wired it so I could check it on the battery, and the pump still works.

With a test light, I checked the power to the pump, and there is nothing. I have checked the fuse (the one in the boot next to the battery) and it is fine and getting power.

I am at a loss at this stage. Is there a relay for the fuel pump? If so which one is it so I can check it.

Could it be something else?

Any suggestions would be great.

Jeff.

there is a fuse and relay in the boot next to the battery for the fuel system

ther relay is switched from the ECCS relay in the passenger kick panel..

i had a similar issues in my car after i used the std wiring as a trigger for a 044 pump ...

had to rewire a switch manually to get me going and havent gone back to find the issue that caused it

Thanks, I will check for the relay in the boot today and see if that is the problem, and if not I will go back to the one in the kick panel.

If that fails I will just hard wire the pump and see if that is actually the problem.

Whatever the fault, make sure your pump is controlled by the ecu, not some switch etc.

In the event of a crash, you don't need squirting fuel all over the place and the ecu will time out the pump when the engine stops.

Very good point. I want to get it back to working like factory again, I don't want to have some bodgy switch somewhere.
