I knew it was too good to be true...

Had a fantastic drive in the Scim earlier, after finishing installation of the electronic fuel pump (sadly the electronic ignition is still in the box). The car ran faultless, pulling hard and smooth, even started first time at the petrol station so fingers crossed the fuel vaporisation has been well and truly sorted. When I got home, all chuffed I decided to just tidy up a few wires ect underbonnet. And guess what, it will now not start, fuel is there but appears to not be sparking. Got a bit dark to do any real diagnostics, BUT I noticed that the Voltmeter was dropping to zero during cranking, and SLOWLY returns to 12v when cranking stops. Bizzarely it still registered zero volts even with my van's jumpleads on, so I doubt it is wired directly to the battery?? Does this ring any bells with anyone to which wire may be faulty?? Longshot, but its cold and dark out there!

Voltmeter is wired straight to the battery via the 50A ignition fuse and the ignition switch according to the 5A diagram I have.
Bad earth lead perhaps?

Cheers, that seems like a logical place to start looking then! Will dig my wiring diagram out, thanks.

I have brought a GTE 5a as a project car in New Zealand. I drove it back 660km home, and it broke down 6 times. I think there is a vapour lock issue, how did you sort your fuel vaporisation issue?
