Bump starts fine on ignition but no fuel/spark when cranking


Recommended Posts

Hi I'm having fun with my vr6 electrics.

I drove to the shops a few days ago and when I got in the car to drive home I had a no crank no start issue but I managed to bump start it. Since the I have done the following..

Bypassed immobiliser which meant it cranked over but had no fuel or spark. So I spent a day removing the entire laser line immobiliser from my car but still no fuel no spark.

But because the car still bumps starts I thought maybe it's a live to the ecu so luckily my brother has the same car.

Tried my ecu in his car to find it cranks but no fuel/spark.

Tried his ecu in my car to find it cranks but no fuel/spark.

What should I try next? because if its the ignition switch surely my ecu should have worked in his car.

It still bump starts fine

Any suggestions would be immensely appreciated cheers
