I need some help. Just put and engine in a 98 chevy blazer, 4.3 litre, 4x4. Went to fire it up, and engine wouldnt turn all the way over, so after i tried everything else, i removed the spark plugs. Then turned the engine manually and as each piston compressed, gas poured from each cylinder, which explains what was keeping the engine from turning over all the way, i just would love some ideas of what this could be so i can get this thing running! Please some help!
