Hi everyone, it has been a while since i posted on here. Last time i was having issues with a used 1.7 i put in my car. Since then, i built a 2056 and got the car running and driving. As i was out breaking in the engine my coil vibrated loose, slid into my throttle linkage and shorted out my ignition system. The positive wire to the coil melted and combined itself with the negitive coil wire. I pulled the engine harness out of the car and fixed the two wires that got toasted, but now the car has no power to the coil when i turn the key on. I have been trying to use the wiring diagrams in the haynes manual to trace the circuit, but i have been unable to figure it out. Those wiring diagrams suck, they look like they were photo copied 3 or 4 times before they made it into the manual.
I also pulled my relay board and did a continuity test to at all the corisponding terminals and the board checks out ok. Im not sure where to go from this point. It doesnt look like there are any fuses anywhere for this circuit. There are some other electrical issues too, but getting the car running is #1 priority. I pulled the fuse pannel down from the dash and the wires that hook to the fuse for the blinkers were melted. The blinkers havent been working on the car, so somewhere there is an issue with that circuit as well. Ignition circuit first though. Anyone have any expertise in this area?? Please help. I must show these gremlins who is really in charge!!

Is it just the coil not receiving power, will your fuel pump turn on when you turn the key? if that doesn't turn on you could always check your ignition switch, im no expert but that could have been fried as well.

The fuel pump was wired to the positive on the coil when i bought the car, so im not sure what is up with the fuel pump circuit. I was thinking it may just be the relay for the fuel pump that is bad on the relay board, but i havent dug into that yet. Is there a relay or fuse or anything between the ignition switch and the coil?
