I will second Amarin's suggestion of checking the radio suppression relay. A fuel pump can be just fine but if the injectors are not pulsing there will be no fuel injected.

The relay is in a black case measuring about 3/4" x 1" x 1 1/2". The case is sealed to the base with silicone. I believe the relay on a 1990 Rex Regina car is mounted very near the coolant reservoir. Actually there will be two identical relays mounted there. One is the radiator cooling fan relay and the other is the radio suppression relay. I can't tell you which one is which but if you use a jumper wire as described in the next paragraph and the fan engages then the radio suppression relay is the other one.

Remove the relay and insert a jumper wire between the two heavier wires on the plug. Try starting the car with the jumper in place. If it starts you have found the problem. Remove the cover on the relay and reflow the solder on the board joints.
