Re: 3800 series 2 won't start after lower intake manifold gasket repair.

I looked them over again and they all are connected, starting fluid put in and vacuum hoses connected. It did run prior, and the thing is it does try to start, but something in the back of my head makes me lean towards some sort of miss fire or something out of sync.

I regards to hotz28's comment, yes it did look just like that. I did put the old one back on after cleaning it out, with a new upper intake manifold seal and seal at the throttle body, and cleaned out the pcv valve.

now that you mention it you may be onto something. I only put in water so far for the coolant, so what i'm thinking it that if that old upper intake is warped or out of shape then as good as the new seal is it may not be able to do it's job if the upper is not formed well around it. If it's not sealed the way it's supposed some of that water could be getting into the cylinder, and though it may not be filling up, it may be preventing it from firing and the gas/water mixture may be what I found in those spark plugs when I pulled them and since there was no color to it yet nothing stood out, it did smell like gas but in hindsight perhaps not as strong as straight gas.

does this sound plausible? I hate to tear it apart again without having good reason. Should I try starting it again, collect some of that fluid that I found in the spark plugs and try to ignite that to see if what's going in is combustible?

thanks for the input so far guys.
