Maybe the starter motor playing up when it gets hot?

When you say it won't start, does anything at all happen when you turn the key to crank the engine over?

And can you elaborate on "alternator and battery ok"? Basically we need to establish whether the non-start problem is because the starter motor is malfunctioning or because it isn't getting power (battery/ immobiliser).

Sounds like the classic hot start problem to me.

or what ever the text talk version of that is!

hi thanx for replyin it turns over ok just not fast enough to start it whats the hot start problem ? >> Edited by vapy on Monday 21st November 19:15

The classis hot start problem is where the starter is completely dead and nothing happens when you turn the key. Your problem is something different and rather unusual. I would guess you have either a poor connection somewhere causing a voltage drop when hot, or the starter motor itself is knackered and losing power when hot.

Is the car connected to a trickle charger overnight? If yes, this is why it manages to start OK in the mornings and I suspect that either your 100A fuse has blown or there is a poor connection between battery and alternator usually at the fuse position.

Peter was thinking that the car was connected to a trickle charger, and that's why battery was recovering.

As V8 says, sounds that whilst summat is hot, the voltage is dropping somewhere. (a variation on the hot start problem!).

If it's fitted (and not all cars have it), it will be near the starter motor. That's on the offside (driver's side), sometimes fastened to the chassis rail.

Could you also possibly invest in a dictionary?

Thx u m8.
