Was going to install the new dizzy, but due to lack of experience, wanted it to be the last thing I'd do. Honestly thought it was the fuel pump and changed that, then maybe the leads or coil so changed them, then was told by an associate he had the same problem with the dizzy module so changed that and all fixed. Will eventually change the distributor when I get a hand down the track, but at least the car is back to normal and driveable now.
