check the fuel pressure at the test port ...low pressures / defective fuel pump, wiring, regulator, relay, injectors ,could cause this .

with your 93 I don't have the pressure spec's ...search the forum or your repair manual... on my 1996 it is around 47psi...what ever pressure it is it should hold to with in a few psi. if it drops rapidly then you must locate the cause ....usually the fuel pump...

Try the little things 1st!
1) fuel pump relay, fuse, and filter.
2) fuel pump pressure

1993 TBI - fuel pressure should be 9-13 PSI.
