Hi, I recently purchased my mates Fiesta RS Turbo after he caught it alight after catching a ratchet between the battery terminals, how he done it I don't know but there was a vw type battery jacket around the battery and that somehow managed to go up! It made a mess of the wiring, so when I got the car I got myself a whole new loom to change with the burnt one. Prior to this the car ran fine, I changed everything in the engine bay, wiring wise and joined it where the car loom goes through the bulkhead in the top left hand corner. But when I came to start the car I had no spark or fuel, an auto electrician came out and said the ecu had been spiked from the damage but the rest of the wiring was ok... With another ecu fitted I now have fuel and spark and the car will run but only after every 5th or so try of trying to start it, once running will cut out after about 20 seconds. I tried tow starting it, again it will run but as soon as you press the throttle it cuts out, if you don't press the throttle and dip the clutch it will idle at 3000rpm.

All im after is some ideas to try as wiring is not my strong point and I need something to try next... Thanks for any ideas people come up with...

Matt.

 

could you not call auto electrician back so he can see whats happening he might be able to pin point it

 

Kind of sounds like a fuel pump not priming. But the curing out business could be a vac pipe? Have a look see if the big one to the servo is ok? And I'm assuming you have checked all fuses?

 

Does the fuel pump prime for 3-5 seconds and go off on ignition 2? With engine off

Are the vacuum pipes and servo pipes connected right?

 

Yes the fuel pump primes as it should with ignition on engine off, I will check the vacuum pipes and fuses and everything again but im sure they are ok...
