OK, you say you have 2 fuel pumps. One in the tank and one on the engine. I'm guessing the one on the engine is mechanical, and the one in the tank is electric? Have you verified the one in the tank is working? If you want to turn the engine over without using the ignition switch, you can get a bump starter switch, or build one too.

You will hook one alligator clip to the power cable on the starter solenoid, and the other to the s terminal on the starter solenoid. When you hit the push button the engine will crank. Please make sure the vehicle is in neutral with the park brake set if a manual trans, or in park if it is an auto.

I'm still trying to figure out why you need 2 pumps? 1 should be plenty if this thing is near stock.
