waht do you mean? Need more information.
You say you let the clutch out and it stalls?
Did you remember to rev it? lol j/k
Does it make any noises? anything distinctive?


Cheers

My advice would be to get under there, check out your clutch pedal... see those switches? unplug it. See what happens. It should be cruise related (EA-ED) but on the EF it might be used to measure incoming load or something who knows.

Anyway try unplugging that plug and giving it a go.


Cheers

You dont think it could be a fuel pump problem do u, like once it reaches the warm temp the fuel pump simply cannot handle the higher pressure ( is that right ) thanks man ???

nah.. the fuel pump only pumps. Its switched on by the ecu using a relay. If its your fuel pump, if you put your foot flat on the aceelerator it won't rev.
Ive had plentiful fuel problems, and this doesn't sound like any of them.
Just unplug those plugs. Let me know also if its a vaccum plug or not.

So some questions:
does it rev?
does it start normally?
does it drive before it gets warm?

Cheers

So it won't start with those sensors unplugged? or just won't start?
if you think its your fuel pump... here's a way to check:
turn your key onto IGN and get someone in the engine bay (cram them in there lol), and tell them to listen for the fuel... its fair obvious.

You might be able to hear it yourself.

Most of the time (this is only possible in sedans, I have a wagon lol, my luck), if the fuel pump is on its way out, you can tap it, and it works for a bit longer...
The fuel pump is under the carpet in the boot. There is a circular cover screwed down... Tap it with the handle end of the screwdriver of whatever and try and start it again.

Don't forget to do all the basic s**t like check your sparks, leads, etc.

Let me know how you go.

Cheers

Lets see... we have fuel, now we need Air and Spark... basic engine principles... So unplug one of the leads, stick a screwdriver(with the conductive part) into the lead, hold the handle, make sure handle is insulated otherwise you'll learn a new meaning of OUCH! And hold the screwdriver near your rocker cover or extractors/exhaust manifold... get someone to crank the engine.. if you got spark.. YAY, if not... there's your problem.


Cheers

explain that one... you unplugged the lead from the spark plug... and then shoved pliers in there, and held them near the rocker cover? correct?
If you got no spark... then that brings it all into a new light...


Cheers
