Rats. With the tests you've done, it does appear the computer is not grounding the fuel pump relay. It needs pulses from the crankshaft position sensor and the camshaft position sensor to do that. If one of those signals is missing, there won't be spark.
Listen for the hum of the pump for one second after turning on the ignition switch. If you hear that, the fuel pump relay is good and the computer has control of it. If you don't hear it, suspect the computer, but before you condemn it, ground the relay coil right at the computer plugs. If the relay clicks on, that will confirm that wire between the relay and computer is okay. Next, there should be four ground wires, two listed as "signal" grounds and two as "power" grounds. The best test for them is a voltage measurement while the relay is bypassed and the engine is running. If you find more than a couple of tenths of a volt, check that wire for a corroded connection to the body.
