TBI injectors not firing on start up

This is a 94 k1500 with a L05 and the injectors are not firing on start up. If I pour some gas into the tbi it will fire right up and run fine but there is something up with the the injectors not firing on start. Any suggestions or something that can help me trouble shoot the problem?

I would check the fuses for the injectors. Could also be a failed fuel pump. Check fuse.

First Guess: Distributor problem. ECM does not get the signal that the engine is cranking.

Could be defective wiring, or other problems.
