Okay, here is the scenario, I drove my blazer to a party, I am in college, after the party I went to start my truck and leave. The engine rotated but would not start or sound like it would attempt to start. I continued rotating motor while pumping the gas a little bit. This is already after the one pump prior to turning the key to engage the choke. Still the engine just rotated and it smelt like gas outside of the truck so due to the time of night I decided come back the next day. Upon arrival, same thing one pump, turn key engine rotates, still won't fire. Tried so much that I ran the battery down. First thought was fuel pump, but after visual inspection of flow am not sure what is correct, when the gas is depressed fuel disperses into two bowls in the carberator, should those bowls fill completely up or not. They probably fill half way up. After rotation of the engine they are empty. So I figured there was no spark. I screwed up by taking the distributor cap off and the wires before manually checking for spark. The rotor in the distributor turns and I took out the control module below the rotor and had it test. It tested fine. So tomorrow I am going to put the distributor components back on and the plug wires and manually check for spark. If I have spark, then what are my possible other problems. If no spark, same as above. Just for general information the motor has just been rebuilt, new pistons (flat-top, .030" over bore), new camshaft, lifters, main bearings, heads were decked, magnafluxed and revalved. Thanks in advance.
