is sure did, sure. must be a 2door car right?
first off on warm days, the fuel pump does not spin for 3 seconds only keyed on, on any 89/90. (not till 91 that happened)
so cranking no full 30 psi fuel pressure is in fact a dead fuel pump, only why is the question.
in many cases it's the bad 29 year old wiring, from the fuelpump relay (main+ FP relay are married in this car) to the pump itself. and ground is 1 of the 2 wires that run the pump , pink and black, a volt meter at the tail light pink wire cranked will be 10 to 11 volts cranking. so if this is true, the 1/2 the battle
is solved, and both wires from tail left down can be bad, there are 2 more splices, below, at center of rear bumper and the tank top that can fail.
but as you side this ground loves to fail.
covered here, fully , see G402?
inspect the pink wire in the connector ?C403 yet, see if the pin is CORRODED? (not green coated)

spec
34.1 to 39.8 PSI. Key on +cranking and idling. never less. this is spec. the ECU and injector are tuned to this pressure and only changes with altitude. on all 8valve TBI.

So I pulled off the fuel lines and I'm not getting fuel to the TB when cranking. I've had this happen before and I managed to get it to work (not sure what I had done) it seems to be an intermittent issue.
I've not checked the ground behind the light will do that next, but other than that I'm stuck and looking for advice.
