Does the vehicle have TBI fuel injection? If so, have a helper crank it while you visually check for injector spray pattern. Check fuel pressure, With TBI around 10 psi.

Can you check for applicable mil codes? You should be able to check those codes, yourself. Use a jumper wire at the A & B terminals for the data link connector. Turn key just till the dash lites come on, no further. The mil on the dash starts flashing, you count the flashes to get the codes. Your looking for two digit codes.
