I just completed the timing chain replacement on this motor and went to start it yesterday. The motor turns over immediately and runs excellent for about 5 seconds and then stalls out. I can restart it again but after another 5 seconds it stalls. I just replaced the timing chain cover, head gasket and resealed the oilpan. I think it might either be a lack of compression or vacuum issue or maybe a fuel problem? I am not quite sure.

What things should I inspect to help solve this issue?

Thanks!
