Even though the pre pump has been replaced, it still may not be doing it's job.

It could be bad/defective, have wiring problems and not getting any juice, or a cracked/split rubber in tank hose. One would think that if the pump was recently replaced, then the hose should have been replaced also??

Try listening for a whine with the fuel filler cap off ,to confirm that it is operating.

Even better would be checking for volts and current draw with a DVOM.

Bentley lists correct current draw at 1-2 amps for 83- early 86 pumps, and 3-4 amps for late 86-93.

If it is operating correctly, and still no fuel,then you would have to pull it and take a look.
