Fuel pump fuse and relays?

Hi All,

2002 Spyder.

I have a little problem with fuelling on the LH bank, there's no pressure at all at the manifold.

Last time I moved it was in the snow, very cold, and it was only firing on 4 for about 30 seconds before coming to life completely. Now it's just firing on 4!

Looks like either a fuel pump (looks like there's two, one for each side), or possibly a relay/fuse has done (would suspect the latter, given it was on / off a couple of times, before packing up completely).

Unfortunately, I don't have the handbook handy with the details of fuses and relays. I'm guessing it's one of the ones just behind the battery in the boot, but could anybody confirm which one it is? Just so I can get a meter on the relays/fuses to make sure they're OK before taking the roof compartment apart!

A diagram or copy of the page in the manual would be superb, or even just a rough guess would be enough....

Car is winterised until the spring, so no urgency at all, I'm just getting on top of all the little niggles over the winter, ready for next season.

Cheers!

Maser, pm me your email will scan those pages on for you,

Having said that...there are 6/7 pages...hold on will check those relay/fuses for you!

Oooooooops...beat me to it!

Gentlemen, that is perfect.

Looks like both pumps run through a single fuse and relay (rather than having separate feeds), and given I've only got fuel pressure on one bank, it looks like a new pump is required.

You guys have managed to shave about four hours off the job fiddling around double checking the pump feeds, so thank you very much!

I hope you can get to the pumps from the roof compartment, it'll make life very easy!

Cheers!

Always happy to help, that's what we are here for, just make sure you repay us by supporting this forum and would be good to see you on one of our meets, check the Events section.

Actually, I have something that might interest you for the technical section, I managed to get hold of pdf manuals for both the Spyder roof, and the full engine strip/rebuild (which I think is quite easy to find online anyway).

If you have a section where this sort of thing can be uploaded, drop me a pm with your email address and I'll be happy to forward them both on to you.

Thanks again for your help on this, it's very much appreciated.
