Hi guys There is a wagon VK 85 with a black 202 with dual fuel carby that wont spark properly. I have connected a plug from the coil and have grounded it to the engine and I only get one spark then nothing. The EST light on the dash wont light up when I switch the car on. I have checked the ignition fuse, that was blown and replaced but still the same issue. Is the computer busted?? I have a few questions about these cars: 1. How does the EST system work? What and where is the sensor it uses to time it properly?? 2. Will a 202 with manual gearbox bolt into a VN?? 3. Can you replace the carbed inlet manifold with a fuel injection manifold easily and bolt on?? 4. Will a auto computer work in a manual car?? Cheers guys, I wanna get this thing started.
