not a clue, i pulled apart the loom to see could i see any wires crossing or anything and nothing, the full loom is un cut and in good condition, never had anything spliced into it bar a turbo timer which had a harness anyway.. puzzle... seems fine now but time will tell

was driving down the the road from his house and the car just cut out and wouldnt start... all lights are coming on with "igntion on" then when you go to start it, nothing... not even any clicking from the starter...there is power going to the starter...all earths are secure, all fuses are fine and everthing else works, head lights, hazards, interior light etc etc etc...

Makes no sense, the ECU has nothing to do with the starting circuit, the engine should still crank even with the ECU removed from the car.

More likely to be a dodgy connection somewhere that you disturbed when swapping the ECU.

hmmmm, food for thought.... nothing visible around ecu tho.. nothing was ever spliced in there either, all clean

There is a start signal that goes to the ecu, so it knows when the engine is cranking and fuels it accordingly. If that wire was shorted to earth, it would stop current getting to the starter motor as it would complete the circuit there. Its possible it could also cause the ecu to go faulty but its doubtful so you could try that ecu in another car to be sure.

If that wire was shorted to ground it would blow the AM2 fuse when the ignition switch was turned to the start position.

tricky one, i have replaced every fuse we could find it that car even tho none were blowen.. we took out the dash this morning just to make sure and the loom is perfect..nothing was ever spliced into it.. all connections in the bay are grand too.. we even re taped the whole loom in the bay to make sure that there wasnt any wires making contact with each other, again all ok... car is running fine now so im just as stumped as you terry... ment to say that when i bridged B+ & FP together yesterday the fuel pump didnt run, this was when the the other ecu was in there and when the engine wasnt turning over, also the EML wasnt coming on with ignition on nor was it flashing when i bridge TE1 & E1.. will try the old ecu in another car and see if its working...

Seen them short before and not blow fuses, dont know why. If the fuel pump was not running when you bridged it, and the ignition was turned to position 2 then its possible the EFI relay was nor energised. Try another relay in and see if it energises when the ignition is turned to position 2.

wasnt the ecu, car cut out again with same symptoms as yesterday..went back over and pulled the bitch apart.. theres a connector in the passenger foot well just in front of heater fan (blue connector in pic below), it wasnt connected properly, when we popped it back in the car started... you were not far wrong terry as usual...

this isnt the car, its a glanza i have in the yard

I think that plug carries the wires to the fuel pump relay, its a little black one just above that on a UK car, not sure if its there on a V or not but.

not sure, the previous owner had the speaker cable wrapped around this and didnt plug it back in properly.. when you unplug this all the symptoms are there so happy days... always something small

I'm sorry to post in such an old thread, but I'm having very similar problems with my GT. I'd really appreciate it if anyone could have a read of my topic over on UKSO and let me know what they think?

I'm also not getting EML on ignition, and have had a gradually worsening intermittent starting fault on my GT. To the point where it now doesn't start at all!
