Missing under load

Thanks Guys for all the input. As of right now, I do not have a OBDII connector wired up. I went to Pull A Part today and got one from a 2001 Durango. The wire colors don't match my wiring diagram. The diagram only shows 4 wires. It doesn't show the grounds and the hot wire. I'm NOT hooking that thing up until I know what is what. If I knew the pin locations on the plug, wire color wouldn't matter.
I did pull the distributor, so I guess i'll need to sync it. That is a piece of information I didn't know. That may very well be my problem.
I'm running the 2002 Dakota fuel pump. I modified my tank so I could keep all the factory components. I have not checked fuel pressure yet, but I will.
