If it won't crank, how do you know it has fire? ...Or , do you mean it crank's over but won't fire up? Have you checked the fuel pressure? Was it running before you changed the harness? These things 14yrs old, the wiring from GM was NOT the best in the world to start with. Check all fuses, grounds, fuel pressure.

Was there a reason you changed the wiring harness? Have you scanned the car for codes? There are inexpensive code readers for OBDII cars like yours. Don't work on these cars without one.
