shorted somthing clicking noise from engi

Don't ask how but I shorted my electrical circuit by accidentally touching the positive circuit to the silver metal behind the PCM, (Engine Block)? It was connected for about a good longgg second before I got to it and removed the positive cable from the engine block.

While the cable was touching the engine, the car attempting to crank itself. Fan clutch got to moving and everything.
I put everything to normal, and tried to start the car. Nothing. First thing I noticed where my gauges, which where outta wack and was denoted my the "Check Gauges" service light. Everything from Seatbelt to Secruity is going off. Mind you I have no Factory Alarm. Second, my "Service Engine Light" alluminated but was real dim.

I checked my fuses and @ my BCM I blew Body Control Module 4. Replaced it.
When I try to start my car I don't get anything but a real loud clicking sound from the top of my engine block. Kind of like a really loud relay clicking. I'm going to investigate further as to where the clicking is coming from.

Any ideas??? Any Help is GREATLY appreciated
Thanks

Update*

I completely unscrewed the whole PCM Module (All three plugs). Tested Ignition to see if I still got a clicking sound. No more clicking sound. I reconnected and the clicking sound is gone, but my car still won't start and the guages/service lights are still outta wack.

Are you sure you checked all the fuses?? and you did not mention what type of car or truck your working on, alot of cars have more than one fuse box, which I am not sure you know or not. I would also check to make sure the ground to the pcm did not get dislodged somehow.

Sounds like a bad connection on the battery. good luck
