Thanks again all for the responses.
Unfortunately the old girl still refuses to kick into life.
I did locate the PTCM but unfortunately couldn't identify the plug terminals C3, 13 & 26. I followed the wires back from the crank position sensor to where they entered the loom then followed that piece of loom back to the PCM. I counted 9 cores on the diagram and looked for a connector with 9 cores but none found. 10 cores, 7 cores and another with 20ish cores but nothing like that going in the direction of the crank sensor.
Not being familiar with the fuel pump mentioned in earlier thread, there is a quiet fan like noise when the ignition is switched on. I'm assuming that's the fuel pump running.
I'm at a real loss here but don't want to hand it to a dealer for them to add double '00's' or even triple zero $$$ to something I may be able to do myself if I can only identify what the problem is! Very frustrating.
Back to the purchase of a code scanner, does anyone think this might be able to help me identify the cause of this or will it just give me a load of information I can't use or dont need?
Again, appreciate everyone's assistance on this. Thanks,
