Re: fuel pump not working.
I would say your problem is your earth to the fuel pump relay.
Re: fuel pump not working.
was thinking/hoping something like that, where do i find that earth then?:scratch:
Re: fuel pump not working.
Right Gary, wiring diagram shows the relay is earthed through pin 21 on the ecu.pin 21 should lead to no. 85 on relay. So if this is earthed correctly and 12v is present at 30 and 86, 87 should Provide 12v to 86 on second relay. Second relay is earthed between second relays 85 and 17 on ecu. If this is all correct it should fire injectors and fuel pump. I think this is correct, :eek: it's late I'm tired.:wasntme:
Re: fuel pump not working.
now im even more confused:crap::laugh: so if one relay is broken both wont work:scratch: Il have a read in the morning cheers matey:laugh:
Re: fuel pump not working.
Yes one relay triggers the other.
Re: fuel pump not working.
I can get a wiring diagram up tomorrow night as I probably not making sense.:laugh:
Re: fuel pump not working.
The wire coming from the relay that's supplying 12v to the fuel pump and injectors is grey and red, probably. :laugh:
Re: fuel pump not working.
its super Andy to the rescue :cooter:
Re: fuel pump not working.
thats the one i have taken to the the old gtt relay and bypassed it and connected it to the white wire that goes to the fuel pump. Must be a prob with the relays as i did the wiring so there wont be a problem there will there:scared::wasntme:
Re: fuel pump not working.
cheers for the help tho matey going to get some relays then pop down to the car and have a look:rolleyes:
Re: fuel pump not working.
if its not the relays then its probably an earth like i mentioned earlier, this is what i mean
haz, puts these things into better english. :laugh:

Re: fuel pump not working.
cheers for the help buddy. il most prob be going down to have a look in a few days so il let ya know how i get on;) So im looking at earths, relays, poss tdc sensor etc... ordered some relays just in case as i need one any way better to not need it and have it and all that:D
