R reg Peugeot 306 petrol engine. Has had issues with sometimes over revving when engine idling for about 18 months. 2 different garages have looked at it and can't find anything wrong. More recently the car has refused to start on occasion. We've checked the battery which seems fine. Also the problem seems to be if I've stopped the car for a short period of time and then try to restart it. Tonight it refused to start, five minutes after stopping. Engine turning over but not firing - tried loads of times. In the end called Green Flag. Went back to the car half an hour later to get something and gave it another go for the hell of it and it started! What is going on?

Next time it refuses to start don't wait for it to make up its mind-do below immediately to determine if its fuel or spark problem

Get a helper disconnect a sparkplug wire or 2 and ground it to the engine atleast 3/16 away from ground-have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel related problem, Do you hear the fuel pump come On when you turn key on? If not check fuel pump fuse and fuel pump relay if okay-check the fuel pressure to rule out the fuel filter/fuel pump/pressure regulator and listen to the injector/s are they pulsing or hook up a noid light. No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil packs, coil's resistances, cap and rotor, distributor pick-up coil, ignition control module, cam and crank sensors and computer Note: If it doesn't apply disregard it and keep testing
