starting problem

[phil1981]

just bought 1999 corsa envoy 973cc and all is going well apart from one thing.after being out on a journey for any length of time,engine will not restart until it has completely cooled down.when this is happening,management light remains on whilst engine is turning over.after an hour or so engine starts first time and management light stays off.had cam sensor replaced but still the same.

just signed up to this forum so would greatly appreciate any replies.

thanx in advance

Sounds like the idle control valve. This deals with cold starting and if it's stuck will be hard to start the car when warm. Try cleaning it first, if this doesn't help replace it.

il tell ya exacly what that is crank shaft sensor 20 pound off ebay had the very exact problem its located just above the sum i think its an external torx screw all you do is undo th torx pull the sensor out, unclip the plug on it push it back into the hoe and do the bolt back up.100% positive mate

thanks guys.ill try both these things out first and let you know how it goes.

I Can insure you it will be the crank sensor

[Timmy corsa B]

I bet when you turn the key the engine turns over and over but doesn't fire

[phil1981]

yeah thats right.not until engine cools down

[phil1981]

seems to start ok though if you fire it up within 5 minutes of switching off.dont understand that 1

[phil1981]

is it possible to replace crank sensor without having access to a ramp

[LesterPiglet1]

Yep, jack up drivers side of car and put in an axle stand.
