The wire should not be hot until the relay is triggered. The relay does not get triggered until the ignition key is turned on. It will run for 3-5 seconds or until the system pressure it at max.

sounds like you jumped a tooth on your timing belt/chain. the wait to tell is first identify number 1 cylinder, then find number 1 on your cap, place a peace of tape right next to it or mark it with a sharpee marker or scribe a mark, however you do it mark it so you know where it is once the cap is off. then remove the cap and rotate the crank until you are at TDC (top dead cylinder) once there look at the rotor, if its not pointing at your mark than your valve timing is off and you need a new timing set. (if you cant find top dead then remove the valve cover and rotate the engine until all the valves on the number 1 hole are closed. once they are all close this indicates the compression stroke and number 1 is at TDC)
First key on you should hear pump run a couple seconds if you think it's the pump have someone crank it over and another pound on the fuel tank this sometimes makes the pump motor start to run, if it does that may be enough for you to drive to a shop for a new fuel pump.
