are you getting spark? if you get no spark, ecu won't pull down fuel pump relay (needs rpm signal first). make sure you're getting spark. also, tach needle should jump when you crank the starter; if not = hall sensor dead. could also be ign. contrl module even if u get the needle jump.
the fact that the car won't start even with pump jumpered w/12V suggests something else is wrong. maybe system relay? may need to pull knee bolster to gain access to the system relay (& pump relay), which are situated just above the jetronic box on pass. side, in front of door, behind carpet.
could also be ecu... known failure mode for this year: it ceases to turn fuel pump on. however, you did mention that it still wouldn't start even with pump jumpered. rule out system relay.
i am having the same problem currently. have fuel pump, have spark, still have no start, even w/known good ecu. problem is somewhere between ecu & injectors i think...
let us know how you make out with it.
