Cranks no start

After the pump quits I can check for voltage and I get 11.7 volts before during and after the pump quits. Is the only thing that can be bad is the pump?

The pump guy still swears its an electrical problem, so I asked him if the pump is getting voltage why doesn't gas come out of it. I got no reply he also said I need to get professional help I dont know if its for the car or me personaly

I'll try that let u know tomorrow

Ran a jumper wire from the battery to the pump there are 4 prongs on the pump I get voltage at the middle two coming in to the pump but if I touch the jumper wire to the middle two prongs nothing but if I touch the outside two prongs pump comes on, it is not easy getting to the prongs they're about a half inch into the male side of the plug and trying to touch the connections with a fuel tank 3/4 full of gas and sparks coming from the jumpers as you make contact. I think my luck is running out. The fact that when I installed the second pump it started right u, then quit with the jumper the pump doesn't quit but when plugged in to the harness it quits but no fuel comes out, either way but why does the pump quit is there some kind of safty switch that shuts off the pump if no fuel comes out after so long
