Engine turns over but won't fire

Sidecar fan · Jul 26, 2012

This has happened twice to me - once on Sunday and again yesterday. The engine will turn over rapidly but just not fire - we checked all the fuses and all were OK. Left it in desperation and then about an hour later tried again and it fired!

Someone said it appeared there was no power getting to the ECU but surely this wouldn't come and go.

Really do need some advice as I am losing confidence in driving it - never knowing if I stop whether it will start again.

Sounds like a failing crankshaft position sensor

It would help to know what car it is, P38, Classic, petrol, diesel.

Check the under bonnet fuse box for signs/smells of burning loose connections etc. Swap the ignition relay, check the in tank pump is working.
