Just rebuilt BAXA put it back in went to start it and it ran for 3 sec and cut off. Tried again same thing. Third time just cranks. Checked timing it's perfect.have spark. Fuel pump is running. Did I not plug something back in???

 

I'll elaborate a bit. Drove car into garage removed and rebuilt the 4 speed. Put it back and now it cranks and blows air from the throttle body. I did compression test and got 150 on all 4. It's got spark. Fuel pump is running but I tried some starter fluid anyway. Still no start. I checked timing and it's dead on. I'm at a loss. Please help.

 

Check your engine grounds.

 

Checked grounds there solid. Is there a chance the spark is weak? How do I measure that? Why is it blowing out the throttle body? I'm afraid to swap the engine cuz it seems good.


at a loss

 

Noticed the timing belt is a bit stretched not stupid but has some play. The timing still sits dead on. Could it be burned intake valve?
