every key cycle(5 secs appart) will turn pump on for 3 seconds.This is done to insure pressure at the injector when cranking,otherwise hard starting would insue.The engine computer drives a relay in the underhood junction box which sends 12 volts to the pump.An audible click of that relay and the pump can be heard key on/engine off for 3 secs via the ignition signal to the ecm which drives the fuel pump relay.

Ok,well need a little more info,but here it goes. Is there power to the pump with the key on for 5 sec. or so is all it will stay on unless cranking. Check the fuel pressure. If there's no power anywhere but the starter then it's a bad fusible link. There's basically a wire that acts like a fuse & they're bolted to the main post on the starter. There could be some in the fuse box under the hood also. If the fuse link is bad,you can either use an ohm meter of just wiggle them with the key on until something lights up, then be sure to use the proper fuse link wire not just any wire type works safely. Make sure it's roughly the same length when you splice it in,longer it is the more resistence it handles,fire hazard. The under the hood fuses are just plug in. Write back if you need more help.
