If you have voltage to the fuel pump it should run unless one of 2 things, he fuel pump is bad or the ground is loose/bad. It would have nothing to do with security if there is voltage to the fuel pump. You can check the ground, by placing the positive voltmeter lead on the ground as close to the pump as you can get it and placing the ground voltmeter test lead on a good metal ground or if you feel like making a long jumper wire, attach the ground test lead to the negative battery terminal., Then turn the key to run or have someone else turn it to run, because you usually only have like 2 seconds that the fuel pump relay will send voltage to the fuel pump and check the voltmeter while the fuel pump has power. the volt reading on the ground circuit should be 0 volts, if it reads anything over that, that is the amount you are loosing because of a bad ground. If for instance it read 12 volts, that would mean that the ground is completely not hooked up, if it read let's say 4 volts, the ground could be loose. If it does read 0 volts and you have 12 volts going to the fuel pump, then the fuel pump is bad.
The ground is at the left door sill. Here is the wiring diagram,
