2000 olds bravada replaced intake gaskets and now can't get to run. Have adjusted distributor various times thinking it was the timing I did the edi engine timing proceedure. I will do it again today, I have fuel and spark. I need help to fix this

 

when you crank the engine what exactly is it doing?
no reponse?
terrible idle?

need some details.

 

When I did a intake on my 98 I had to crank that thing like 100 times. The cylinders were so full of antifreeze and oil. After it finally fired up. Took a while to burn all that crap outta there then ran great.
