I had exactly the same problem and I found the answer. Under the carpet on the drivers side there is a ground junction (bar with tabs and black wires). It is the junction for the grounds from the fuel pump, power locks and windows. It is a poor design and the tabs get loose and moist under the carpet causing the fuel pump and power windows,locks etc to shut off. I paid about 3 tow truck drivers before I figured this out. Just take the junction apart and solder the grounds to it. Hope this helps!!

I would recommend some more tests on your 1994 Oldsmoble 88. You should try and determine if the injectors are loosing their 12v power supply or the ground signal to fire from the Powertrain Control Module. If you are loosing the 12v signal then backtracking the power supply to the injectors would be the next step. If you are loosing the injector signal but you still have spark the fault could be with the ignition module, PCM, or the wiring between the two.
