Engine Mechanical problem
1991 GMC Van V8 Two Wheel Drive Automatic

i replaced a intake manifold gasket on a 91 gmc G3500 passenger van with a 5.7 L V8 engine. i went to start it and it backfired and then just turned over and would not start. if i let it sit for a couple hours it will backfire again and then just turn over. i was wondering what could cause this

Check to see if distributor is in correctly. #1 TDC pointer should be close to 0
