46Echo

I am praying yall can help me. I have a 1985 Leland Defender 110 3 door. The previous owner transplanted a 1999 Disco 4.0 V8 into the Defender. They did an okay job with the install, but the wiring is not very clean. Also, due to some unfortunate electrical issues, I also replaced the complete factory vehicle harness. The issue I am having is, I cant quite figure out how the ignition, plug wires and coils should all be wired up. The ECU is the Megasquirt 2, with a 3.0 board, DIY Auto relay board and, EDIS module with 2 quad coil packs. I have searched the web for the firing order for this engine. But I cant seem to find which coil and or terminal goes to which cylinder. The engine tries to start, and when it does it sounds like its missing and running on 3 cylinders. Respectfully, Paul S.
