This is a question for a mechanic. If the fuel pump is running and the pressure regulator is OK, there's no reason you shouldn't have fuel, unless the injectors themselves are all faulty, which seems unlikely. Putting in a new computer may have complicated your problems if it was not the correct computer by number for your vehicle.

check all of your fuses before you buy anything

Ok sir something is not adding up. If you hear the fuel pump run then there WILL be fuel at the injectors. Push the fuel test access port and a good pressurized stream should be there if not PUMP again. IF no fuel, the pump is no good or fuel filter is plugged Sounds like a fuse to me ... Check the ECM fuse, in that year they have a few stupid things in with it or quick way is to put a scanner on it and see if it "communicates" if fise is good it will commnuicate fine. While there check codes, there should be some if its a computer related problem. IF ALL OF THESE TEST GOOD it is a security system problem. Try a different key Good Luck
