Are you sure its not an immobilzer thing?

if your using the remote central locking make sure you start it immediately after locking and unlocking it

 

[Guest]

Just make sure the immobilizer icon (little orange squigly line) comes on in the bottom right hand corner of the dash

otherwise it will turn over but wont fire

Is it a ph1 or ph2 car mate?

 

[Guest]

mk 1 ph1 1992

95% sure the wires that run from the pump and sender (under the rubber cover) to the other main pump (on the passanger side of tank) will have broken!!

Common fault!! Know of quite a few ph1's with this problem!!

 

[Guest]

I had same problem with my ph1. Removed rubber cover to look at fuel pump and found the plastic plug on end of the earth terminal was melted and not connecting properly. Cleaned the terminal and reconnected it and the problem was fixed.
