I started working on the kit again since it is nice here.

I disconected the window switch and it seems to spray fuel. Is there anyway to fix a window switch or tell for sure if it is broken?

 

Would reving the engine to a point within the rpm range and then taking a countinuity reading tell me if the rpm switch is working?

 

Yes. Program the RPM switch to activate at say, 2200 RPMS. Open up the RPM switch and find the positve, or ground, wire that it switches on. Connect that wire and the opposite wire to a Mulitmeter. Turn on the car and rev the engine to 2200 RPMs, and see if the multimeter reads anything or not.

 

I tried it and it didn't work but I am not sure if that is the only problem. I've gotta keep looking

 

While you're troubleshooting set the window switch low so that it activates while the car is idling ~400-500 rpm. If you get the output you want you know the switch is working, so the coil, 12v, and ground are good. If you don't get anything check your power and ground. There's only 3 inputs and 1 output, so there's only a few things to check.
