Hi guys, im having some trouble with my car, it starts well, runs well, but after some time it just cuts out and wont start. It has to cool down for some time before it starts without any issues again. Im thinking it has something to do with the engine fan not switching on. Any idea where i can start to check it out? Thermal switch, fan relays etc? Thanx!

Check for air in the fuel lines between the filter and the pump on the front of the engine.

When it cut out? Under acceleration only, or just whenever it wants? CPS faults are common, usually happens when hot engine. When going bad CPS may loose proper signal totally and this cause engine to cut. Fault codes would tell...

I was going to say Crankshaft Position Sensor too, but the usual answer is to get it on StarDiagnose rather than just randomly changing parts.

Sounds like crankshaft sensor fault, but try this.........During the event when the car will NOT start, keep cranking the engine and see if the rev counter needle moves, if it moves then its likely that the CPS is ok and the fault is elsewhere.
