I've been trying to track down an electrical problem with my FI and I've found more problems.

1. When I turn on the ignition switch I blow fuse #9. The Haynes manual says that this fuse powers the turn signals, brake lights and back-up lights. Also, I noticed that the buzzer sounds when I turn on the key, regardless of both doors closed or open. Anyway, I disconnected the brake light switch at the brake pedal, all of the wires to the turn signals and disconnected the back-up light wire at the tranny but the fuse still blows, which then stops the buzzer.

2. No power to the coil. I've replaced the ignition switch with another one, but I'm still not getting any power at the coil. I've checked the continuity between the ignition switch and the coil.

I have power to all pin #30s on the relay board in the engine compartment. I have power at the large red wire at the ignition switch.

I feel that I'm very close to getting this car running, but with these electrical gremlins I'm extremely frustrated...(IMG:style_emoticons/default/mad.gif)

Any suggestions and/or guidance would be greatly appreciated....

Latest update:

Well, I'm out of town this week, but thought that I'd give you guys an update. Before I left, Saturday, I had the dash out, the ignition switch out and was testing ALL of the recommended wires and/or connections. I was finally able to turn the ignition on without the fuse blowing.... (IMG:style_emoticons/default/smilie_pokal.gif) , but I don't know exactly what I did. (IMG:style_emoticons/default/dry.gif) Anyway, I put the dash and steering wheel back together. As I put one major section back in, I tested the fuse. Everything working great. So, I was ready to start the engine. Turn on the ignition, POW, there goes the fuse. WTF????? Anyway, before I started taking everything apart again, I got underneath the dash and started looking for loose wires. Well I found (2). One was a red wire, for the radio which I had removed, and another was a red/white wire that was suppose to be attached to a dash illumination bulb, it was touching the dash. So, I replaced the fuse, held the wires away from the dash and turned on the ignition. No problems. (IMG:style_emoticons/default/aktion035.gif) So, I think I found my problem, but I still want to check a couple of more things....
