Help! Blew my Interior Light/cigar lighter fuse, now car won't start

Alright, I posted this to the Vortex forums and got only one response. I'm hoping that someone here might be able to shed some light on this.

Here goes: I was putting in some gauges yesterday in the compartment below the ashtray and lighter (MK3 GTI). Air/Fuel, oil pressure and voltage. When I first started the car it ran fine. Only thing I noticed that my Oil Pressure gauge was pegged past 150 PSI. Now I think I bought the wrong sender (10 Bar might be too much, so perhaps the 5 bar would be the better choice.) NE Ways, I went to disconnect the pressure wire from the back of the vdo gauge and accidentally touched it to the 12 V wire which blew the #21 fuse. Replaced it, checked other fuses (Fuel pump etc.) all fine. First, I thought that the cigar lighter was a switched 12V source but according to my voltage gauge its always on. Ok, so I guess I will find another wire in the area for the 12 V switched. Suggestions? So I go to start my car, and it will turn over just fine, but it wont catch. I think its ignition related, my plugs and wires are brand new, but my distributor has been in for about a year now. The coil pack is probably 12 years old. So if I pull a plug and crank the car and see no spark that probably means that the coil is bad? Right?

NE One have any other ideas?
