Fueling & Injection - Having issues with one of my pumps

Hey guys I finally started my AES 390 yesterday but it would not crank over the first two times. I noticed it was not getting any pressure with one pump hooked up. So I went to hook up both pumps and the engine cranked over and started. I switched pumps again and it would not crank over or build pressure. Lonnie advise to check the relay but i can here it click when I turn the key. I have to go back and check the grey connector, the one that connects to the harness to see if a pin in there may be bent or something. Has anyone had this issue before and what did it turn out to be. Thanks!!

If you call me when you are near the car, I will go through a start to finish diagnostic procedure to determine what is wrong.

Yea thanks Lonnie just trying to see if anyone here had experienced the same thing and could help me diagnosis this quicker. It's going to have to wait for Friday or Saturday the wife is getting upset, spending to much time on the car. LOL
