Check fuse for fuel pump, and for voltage @ #11 F22 15 amp

check for burnt connections where the relay fits in place.and check for 12 volt to one side of small pins with engine cranking and check for earth to the other small pin at fuel pump relay.

make sure you are getting the voltage (V) to the relay. Sure, you can easily bypass this aspect of the relay by shorting the contacts [enables V to relay] but that is entirely different V for the load rather than the V for the coil [which provides EMF, closes relay, makes contact, laaaa].
Evidently, you are getting V to the load [pump turns on once bypassed].
You aren't getting V to the coil side of the relay. Go back and recheck the wiring as well as the pump fuse. Take it out and do a continuity test [out of circuit].

had this problem on my neighbors 98 chevy truck with the same engine !!
it turnd out too be the fuel pressure regulator,you have too pull the upper intake too replace it!!
SOURCE: Fuel pump constantly runs
sounds like you haven't got the right relay or the replacement has failed. pull one relay at a time and go back to the rear of the vehicle and listen for the pump. make sure the key is on when you do the test.

sounds alot the the pcm it controls the fuel pump and ign system but the anti theft would keep it from starting because the key has a transponder in it programmed for that vehicle and that would kill all ign if triggered
