MG MGF Technical - strange starting...help

dunno if anyone else has suffered with this or can offer any help.
the car starts fine when cold but when its hot, if i try and start it shortly after switching off it gives half a turn then hesitates for a second then turns again and fires.if i leave the car for 20 mins or so it starts fine.its beggining to make me nervous,i hope it aint the starter cause they are about £250 ...ouch.not a difficult job i dont think.....?

cheers

Is it Mpi or VVC, as there are differences to take into account. Coil may be the culprit.

its a 96 mpi,i have made sure the conections to the starter are ok,i have read a few threads with similar symptoms but know answers.

Coil may have a short that connects when warm, but after cooling down it works perfect again.

Can't be the starter or battery as long as the starter turns the engine.

Ignition as said by Johan, or

.. may be to much fuel due to a failure of any temperature sensor (ECU related temp sensors of course).

I'd see for the inlet manifold temperature sensor connection and harness to the ECU and sensor itself.

Wire at the ECU connector

Just one more option.

for a second the starter doesnt actually turn the engine over,it gives half a turn then it seems as though there is some pressure somewhere and the engine cant turn, a second later it turns over again and fires up.this is with the key still held on start.

i thought it could be timing but its not adjustable is it?
