1998 Mitsubishi Diamante Engine will turn over but will not

I have a 1998 Mitsubishi Diamante with a 3.5 L V6 SOHC engine. I have replaced the timing belt and water pump and the engine turns over but will not start. I found that when I replaced the belt that my timing marks were off so by trying to start the engine I could have bent the valves. I have taken both valve covers off and there was no slop on the rocker arms. I also took a compression test and # 1 piston had 195 lbs, #3 piston had 210 lbs, #5 piston had 200 lbs, #2 piston had 210 lbs, #4 piston had 205 lbs and #6 piston had 205 lbs, of pressure so I think my valves are OK. What else could be causing the engine not to start.
Thank You
