right, because i was stranded i got the RAC out, and it turns out the fuel pumps are fine, he had a play about and discovered that there was no live to the ignition coil, or a little plug below the dizzy or that big plug on the ECU type thingy under the scuttle panel. it then managed to randomly start and i got it home and now it wont start again, the RAC guy said it could be the immobilizer playing up so i phoned the guy that fitted it (its a Clifford 650 or something..?) he had me do a test which proved it works fine so its not that, so to sum it all up... it turns over but doesn't have the live feed to the things i attempted to mention above so doesnt start, its not the fuel pump or the relay or the other fuel pump or the immobilizer. and all this is intimitant and rarely it starts.
