Answer
Hi Patrick... if you have no power at the pump check the circut, the fuse and the relay. do you have power to the relay when you turn the key on.also check the oil pressure sending unit for an open circut as it also controls the fuel pump circut. another test is the fuel pump test wire.there should be a wire on the drivers side of the engine. it will have a female connector on it. single wire only. that is the test wire for the pump. put 12 volts to it and it should turn on the pump. if it does the problem is in the relay/ fuse circut... hope this helps
