hello, I have Vauxhall astra elite 1.8 (06 plate) auto.
After short run then I stop for 15 mins, later the engine don't turn on about three times,no crank. and after this the engine is on. In the morning the engine starts all the time. What is a problem?
And how to do fault test?
I tried pedal test but nothing was shown.
thanks

It takes 3-things for an engine to combust-compression, fuel and spark-

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 so, 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
