So turns outmy problem from the other thread was gunk in the fuel pump and line, but now my fuel pump isnt coming on with the ignition...

so i test the wires to see if theres a signal first right?.... then no signal its the relay... i can go hunt around scrap site for one... is it the circle topped one or the brown square one?

If there's current its the pump right? i think i've got a bwm one on there 2.0ltr if i remember correctly.. which one off here would it be? http://www.gsfcarparts.com/

Thanks for your help in advance!

its the round metal one i had problems with mine so i cut it off and replaced it with a standard auto relay in a new holder so a lot cheaper to replace in the futer!!!

took pump off, wired it straight to battery, nothing.. then again.. it started. Is it on its way out?... put it back on and everything ok now.

Sounds like your relay is breaking down under load due to burnt contacts or weak coil.They will work on a meter but not under load.
I have experienced this many times at work on various vehicles and circuits. Bin the relays and fit new Bosch ones.
