starting problem

Flys007

Dirtiest truck in Vegas
Newer motor, 50k or so. Put into the truck this week. I have spark. Checked it with a spark plug light. I have fuel. fuel pump turns on, and i can smell it in the exhaust. I have timing. When i was putting the motor in I removed the valve cover and turned the motor over while watching the rockers. When both valves on one closed, and the mark on the balancer was lined up the distributor dropped right in facing one.

When I turn the key, no fire..... Any guesses?
