I just recently exchanged a 4.6 Northstar engine in my 1997 Deville. The engine that I replaced it with came out of a 1996 Deville with the Northstar engine (eight digit "Y"). Eveything connected fine, except now it won't fire. The engine turns over but it will not start. Any suggesstions? I checked and re-checked the ground wires, but still no success.

1st get some starting fluid spray it into the throttle body to see if its a fuel problem. if its not fuel then check for spark. also pull the codes!!!

before i make any other major suggestions i wanna know if its a fuel or a spark problem causing it not to fire it has to be one of the two from their we can proceed but pulling the codes will also majorly help
