Hi
I do have a Fuel Reg, its just the standard one.

I don't have a throttle dashpot, the TPS is set correctly, both air and water temp sensors are operating correctly, I have tried a different MAP sensor to no avail, and different pickups for the Dizzy

Codes I have received were 3, 4 and 7
7 was due to trying to start the car with the TPS unplugged, and 4 was due to trying to start the car with the temp sensor unplugged, 3 I cannot work out, using that diagnostic manual the wiring for the igniter checks out. (gets spark and correct voltage at the ECU)

The only vacuum lines connected are one to the MAP sensor, one to the Fuel Reg and one to the charcoal canister, and these are all connected up correctly as per my previous thread. All others are blocked off.
I am fairly confident that the loom has been done correctly as I had it totally stripped and laid out on the floor to confirm all of the wiring before I installed it into the car

The other problem I have now discovered is that before it temps up and dies, it won't rev above 2500rpm. I only just discovered this last time I started it as I have never tried to rev it whilst it was stationary.
