Question Electrical Problems? HELP!!

Situation:

Basically I have a new motor and trans just sitting in the camaro waiting to be fired up. The camaro has been out of commission for about a year. During which time I rebuilt the motor, had the car painted, and bought a new transmission. Now that everything is back in place, I'm being taunted by some stupid electrical gremlin. I know this has to be something simple, I'm just not sure where to start. Please prove me to be a dumb ***, and tell me to connect some little wire, or replace a hidden fuse. Just get me back on the road.

Background:

93 Z28
Motor and trany rebuilt - nothing to fancy 355 & A4
Engine bay painted - most wiring left in place, just masked off and put to the side.

Symptoms:

Not hearing fuel pump prime
interior lights "Dome, dimmer & Gauges" not working
trunk relay clicks, but does not open the hatch
Radio not turning on, doesn't seem to be getting power
Motor cranks good, but will not start - maybe caused by lack of fuel


What I think is wrong:

I think I may have missed a ground connection, but I'm not sure where. I've checked all the fuses and none of them are bad. No blown fuse and no power must mean no ground, right?

Battery-> passenger side shock tower "behind junction box"
Battery-> Big ground to motor mount
Battery-> smaller grounds to motor mount
Driver's side frame -> coil post mount

Am I missing anything?

Please help. I can't wait to drive my car again!!

Question Re: Electrical Problems? HELP!!

Update:

Okay I've checked every ground I can find, and cleaned them to insure I have good contacts.

Grounds I've cleaned:

Terminal at battery
The ones by the radiator
Coil post
Frame from coil post
Motor mount
Strut tower
Driver-side interior ground "lower door jam area, behind kick panel"
Passenger-side interior ground "lower door jam area, behind kick panel"

I think I've eliminated the ground as being the problem; however, all the symptoms remain.

Please Help!!

Shoebox any ideas?

Re: Electrical Problems? HELP!!

By the way, I'm not looking to fix all these problems right away, My real concern is starting the car; however, given the situation I can't help but believe that all these things are related to one broken circuit. Be it a blown fuse, a dead relay, or damaged wire. I just need someone to point me in the right direction.

Thanks

Lightbulb Re: Electrical Problems? HELP!!

Solution:

Turns out I'm a dumb-***. I connected a black set of wires, which I thought were grounds, to ground, when they should have been connected to the positive junction box. The give away was the pair of black wires, where labeled "fusible link." This didn't catch my attention until, I study a bunch of wire diagrams from shoebox's web site, and tore apart most of the dash board to test various wires.

Now the battery is dead and I'm charging it.

Best of luck to you all, and I hope this post helps someone else.
