My 04 Saturn Ion crank but won't start. I have spark but It

Customer Question

My 04 Saturn Ion crank but won't start. I have spark but It has no fuel to the fuel real I replace new fuel pump relay it still no fuel from fuel pump. replace new fuel pump but still not work. I check the power to fuel pump but only one wire has power when the key is turn to the on position. but that wire only go to the little sensor on top of the fuel pump lid. The other wire does not have power when the engine is crank or when the key is on. it has 7 pins on the connecter. I also check power to the fuel pump relay it has 4 pins that goes into the fuse box but only the middle pin has power and the other pins do not have power. What can cause this? What other options do I need to check?
