Any idea what problem is.
« on: 23 August 2016, 23:21 »
Right i put fuel in tonight. (Yes correct fuel ) went in paid for it. Come out jumped in started and cut straight out.  Tried several times no joy. Rang a friend said it could be immobiliser took neg off bttery for 15 mins no joy. Got a battery brought to me. no joy.  Finally towing it home tried to bump it. no joy tried to start it off the key just to get brakes working . Didnt start first time. Done it again 5 mins down rd. And it starts and runs fine. Multimetre on the batterey  12.84 when off 13.85 when running . And now starts. Any clue coz im stumped. ??

Hi buddy,
I'm a bit old school and used to carbs but do you think it could have been down to vapour lock? It was a pretty hot day yesterday and if you'd been on a lengthy drive it could be a possibility. Alternatively it could be a fuel pump pressure issue.

Long shot but coilpack on the way out. When they get warm they stop working and then when it cools down itll work again?

I had a polo do this and the next day started up fine, drove up the road and cut out but started and ticked over 30miles to the workshop on tow fine

Cheap relays are prone to fail,could be crank sensor.
