engine fired for the first time.... almost

[93GTDIN]

This is in regards to the motor in my signature.

Last night we put the finishing touches on the engine and fired it up for the first time. We had to play with the timing a bit to get it to fire at all, and when we did get it to fire, it died instantly. Some more timing tuning, and we could get it to fire more consistantly. Since then, the only thing we have been able to get it to do is this:

When I turn the key, it fires, revs instantly to about 2000 rpm's (without my foot on the gas) and dies.

It does this every time, and I havent been able to figure out what is wrong. The EEC Test shows code 96 which is "fuel pump circuitry". I did recently put in a new fuel pump, so I suppose its possible I screwed something up down there. My question is, is it possible for the computer to detect a problem from the fuel pump and then keep the engine from idling because it thinks the problem is serious?

Any other ideas or tips are very much appreciated.
