Hi Bud , It looks like no one is answering your plight, Try "BRICKBOARD FORUM " It's an American SITE and it's FREE, your S40 is better served in the USA.

The fuel pump relay should be the one I circled, marked ENGINE or ENGINE SYSTEM in the map. If the fuel pump primes you can check by removing it, it should stop priming.

Ok we have a 99 S40 which wont start. Has spark and injectors are firing. Am told the fuel pump should come on for a few seconds when the ignition is turned on but it is not. All fuses ok so suspect the fuel pump relay but cannot find it.
It is not under the bonnet in the main fuse panel that has a few other relays in it and not under the dash near the steering column that has 4 relays. There are 2 other relays above and to the right of the internal fuse box but they are certainly not placed to give easy access so don't want to pull them out unless totally necessary.

Does any one have any idea where they have hidden the fuel pump relay in this model?

I have checked the system for leaks, including injectors stuck open, and can find nothing.
Anyone come across this issue before?

If there's no other logical reason why it's doing this, I'm thinking the previous owner may have hot wired the fuel pump straght to the ignition for some reason.
Though I'm struggling to think of what this could be masking!

The previous owner had bypassed the headlighter adjuster circuit, and also placed a bypass wire from a pin on the 'engine' relay straight to the chassis / -ve (and for some reason the coils wont spark without this bodge!) - so I dont doubt theres a chance he's screwed with the fuel pump electrics too.


I was going to look at the relay, and whether it was stuck on there - but don't know where it is!
The box in the engine bay names the fuel pump fuse, but not the relay.

Anyone know where it's hiding?

As mentioned, I'm getting terrible MPG, so dont think it'll pass the MOT at this rate :-(


Any help is much appreciated!

Thanks

Do you have a Haynes or owners handbook ??

The fuel pump fuse and/or relay will be in the engine bay box and the headlight adjusters need to work for the MOT.
As you might have a phase 1, check the wiring has not chaffed against the bottom of the radiator, as that can cause a lot of issues, but not fuel pump faults.

Make sure to change the fuel filter if there are no records of when it was done, as that can wear out the fuel feed pump, as can a dirty pump intake screen.

Never put too big a fuse in for a fuel pump, due to a potential fire risk if the pump has a short etc.
