Ok, I don't believe the fuel pump relay will work until the pcm gets it's power from that asd relay and then fuses #16 and #26, so there is a dark blue/yellow wire coming off that asd relay that goes to pin #3 of the pcm. The pcm has to ground this wire in order to activate that asd relay, so let's ground this wire and turn the key to run and see if that asd relay activates, then powers them fuses 316 and #26 and also now power the fuel pump relay and the fuel pump.
If so, then make sure the connector at the pcm is good and tight. If it is you might be looking at a bad pcm, but first disconnect each end of that dark blue/yellow wire and using on ohmmeter, make sure it is ok. Ballpark ohms is 5 ohms. It should be lessor equal to 5 ohms. If it's more the wire is bad. If it's good, also make sure it isn't shorted to ground so place one end of the ohmmeter on that wire, anywhere, then the other ohmmeter test lead on a good metal ground or the negative battery post, if it will reach and it should read infinity or 1 on some digital ohmmeters. I means infinity.
If it reads anything at all, then it's shorted to ground. If so, replace that wire with the same gauge, color and length. If it comes down to a possible bad pcm, you should at least retrieve the trouble codes first before replacing and programming the pcm.
