Have you double checked the earths are good?

[Mears21.10]

I think so one on the gearbox and one on the alternator yer

bypass the alarm or phone Clifford.

How ???? What's the little green wire going to the coil

[meritlover]

trace the wires back to see whether its a fuel or ignition cut and bypass it. Or lift the phone.

there is way too little information on this thread to start describing wire by wire. if i had a pound for every thread that said 'help no fuel no spark' id be a rich man. they must also all still have the same problem as no one ever comes back to say what it was that was causing the problem and that they fixed it.

chances are it will be something common like a crank sensor wire.

is the fuel pump priming when the ign turns on?
and is it running again when it cranks over?
