Hello all,

I am used to working on classic fuel pump fed carbed machines, so this is a bit new for me. I am wondering where to start to diagnose the fuel delivery issue on this sled. It fires up for a bit with starting fluid, so good spark. I took the carbs out and cleaned what I could. I've uploaded a video with the sound the EFI is making (not sure if it is a normal sound or not). Owner said it ran good last year. and He has started it this year but it smoked like crazy. I already fixed that - the oil injector was stuck all the way open. That part operates as it should now. Any thoughts? Thank you!

Dig down to the fuel pump behind the bars, unplug the leads
make jumpers and run the pump backwards and forward a few times and see if you then get fuel to the clutch side of rail
