i recently rebuilt the engine in my 96 gmc and removed the distributor with out marking it. i tried to drop it it one # 1 top dead center like and old 350 but it did not work. you will have to take it to a gmc dealer the timing has to be set with a computer that it is hooked up to it cost me 300 dollars to fix it after messing with it for awhile i gave up and took it to them.

On the 96's everything you did was correct. Double check the #1 is at top position and cresting to drop. 2) make sure the ECM is disconnected this should fire if all plugs and wires are correct. The dealer is to expensive and I can walk you threw it. The manufacturer will preset at 0 TDC then they will adjust per computer as the asthmatic pressure is at its peak. If you can rebuild the engine you can solve this issue with out a dealer. A timing light. Check all the basics on this to verify fuel, air is working.
