Starting Issue

[DIB350]

My S3 has a Cossie 24v conversion. I'm having trouble starting the car after it's been running. Doesn't seem like a fuel issue. Car doesn't turn over and no click from the starter. Immobiliser issue? Car always starts from cold and will eventually start if I leave it long enough. Any ideas? I'm thinking it's got to be electrical.

Thanks guys, will check all of the above. How do I go about checking the immobiliser?

Fuel pump priming. Start solenoid sounds a good bet Andy. I'll price it up.

Okay, checked the main connector block at the ignition and it's a bit frazzled inside. What do I replace it with?

I still had the yellow connector which I believe is a Ford item and always fail. It was frazzled. Weird it wasn't replaced when everything else was? Anyway, I used yellow crimp connectors and then wrapped in plenty of insulating tape. Took the car for a good run and tried a number of hot starts and all seems well. Thanks for the help!!
