Electrical failure on a GTO-3!!

[yellowvette]

Hello everybody !!
my name is gautier and I have 24 years old!! I'am a french guy (live in rouen) and I'am owner of a 2003 noble M12 gto-3 in portofino blue (the french one who is for sale on the PH advert)
but I have a problem after a rainy day on the nurb', I left the car a day on th epark and when I come to pick up her I have an electrical failure!!
I have no fuel pomp (normally the pomp do a bbbzzzzzzz when you turn the key on) and I have no ignition !!
Someone already have this problem ??
thanks to help me and excuse me for my bad english

Check the four relays near to the ECU, from your description you have lost power to the ECU, what other things in the car still work, lights? interior light?

Last one on right. Behind driver seat in engine bay. I keep getting the same problem and just wiggle the relay and mine works fine again. You can just get hand in there

Another thing to check is the wiring to the fuel pump. The session at the ring would have got the turbos fairly hot and the wiring runs very close to the front turbo.

alll on the car work execpt ignition and fuel pomp
the car has been checked two times, (one time by RSR nurbur and one time by MD racing) and all the fuse and relay are good

[Adrian W]

The fuel pump is activated by the ecu, look at relays again, remove clean contacts with oil replace, then check four fuses near Relays.

Also check the ground from the ecu - it goes to the main ground point near the battery. Clean up with contact cleaner, tighten bolt, protect with dielectric grease.

it's one of the 4 relay! I put 4 new relay and all is good !!
2 month for that and 800€ spend on the garage/parts to tried to repare the car !!
it's only the fault of RSR nurbur who check the relay two times and tell me that is sure that the relay are good !!

NO! it wont be the relay itself it will be the base the the relay plugs in to that will be the problem.

I have another problems with the car !!
when the engine is hot (90°) in traffic jam or stop at the traffic light the engine stop and impossible to restart immediatly, I must waiting a few minutes and the engine restart but ten minutes after it's the same situation (just before the engine cut there are a lot of ignition return in the exhaust and a big "BBUUMMMM" and the engine cut)
the car have 24000 miles and must go to the service so maybe is that
I have 6 new ford OEM spark plugs and a new fuel filter I hope this is that !!
A garage tell me that the problems due to the ignition coils ???
thanks for your help

Based on what you have said, I would suggest you contact Either Yellowshead or Jetstream through their profiles on here and arrange to bring the car to the UK fo a couple of days, I think it will end up being your lowest cost option.
