Had this problem for quite some time, very similar. The engine will not start when it is warm. Recently it started dying when the engine got too warm.

It is a sensor that won't work when the engine is (too) warm, and there are two of these sensors.

Since I don't know the actual name of the thing, I can try to explain where you find it and approximately what it does. The price to get a new one is probably in the range of $50 or less (I think). You can *easily* replace it yourself.

My car is a Carisma 1999 GDI.

Remove the top plastic engine cover of the engine so you expose the engine. Notice the cover has insulation under it, to "keep" the engine warm (for whatever reason). Picture:http://i.ebayimg.com/00/s/NDQ1WDU5Mw==/$T2eC16Z,!zUE9s38+F9nBQSeWvMYZQ~~48_79.JPG

I believe the name of the bad sensor is: CAMSHAFT SENSOR.

When you now look at the engine you see the 4 spark plugs. Cables go out from these spark plugs and go to the right. On the right hand side of the right spark plug towards you you see a small gizmo with cables coming out. Attached with a single 12mm screw, a cable coming out off of it.

The sensor itself is the size of a half thumb inside, and it is a magnet that detects the coil position (am I right ?). This magnet tells the spark plugs when to spark. Buy a new one sensor. There's a second sensor like this on another place in the engine but I don't know where exactly - it has the same job.

One temporary trick is that you can do is remove insulation inside the engine-cover around this sensor, or remove the cover alltogether. Makes things cool down faster, or use cooling-spray.

If it wont start only when hot, it could be the fuel injectors.

Car wont start on cold days


Hey. You have to check a little bit more to see what's missing to start the engine. When you turn the key on until the instrument panel lights up do you hear a humming noise for about 4 seconds?

Tryed to start it a few hrs ago it cranks ok & seems to want to start for a few seconds but wont


Your engine needs basically four things in order to start:
> Volumetric efficiency (V)
> Air/fuel ratio (A)
> Compression (C)
> Ignition (I)

V + A + C + I = POWER

When there is no POWER (engine will not start), it is because one (or more) parts of the equation is missing. PRELIMINARY diagnosis is to determine which parts of the equation are present and which are missing. Then PINPOINT diagnosis is to determine WHY the missing parts are missing.
Until preliminary and pinpoint diagnosis is completed, nobody can do much more than GUESS what could be causing your problem.

spark plugs? spark plug wires? coil? if it shuts off when hot, and starts when cold, coil could be problem....could be radiator stopped up causing it too heat, and will go off wait a few and it'll start back up...

Missing out and dies when warm


reach to the underside of your egr valve and feel to see if the diaphragm moves as it warms up. if not you may need to replace it. be careful not to bur yourself though, the engine and egr can get very hot very quickly
