Here are some shots of the fuse box, the relay, and a video of the engine surging.
Some history;
before it was parked and used as storage, it functioned perfectly. The last time I had to move it, I accidentally crossed the battery wires. After that it would not turn over. I ended up rigging an electric fuel pump to it just to get it home, worked, but had the exact same issue, when I stopped pushing the fuel peddle it would die. I’m guessing when I crossed the wires I fried SOMETHING? I’m starting at the relays, but there are a few other switches with power running to them.
Right now, I have replaced the mechanical fuel pump and as far as I know, there was never an electric pump?
detail- while searching for a vacuum leak, I pulled a small hose leading into one of the switches and the idle instantly improved, it ran well until I pushed the gas peddle and then it died. It would not idle again until it was cool.
hope these details, I will keep you all posted with any progress.
