Changed Head, Now NO Start?!

Hi guys, I just finished changing the passenger side head (rotted through over exhaust port). Truck was running perfectly when parked last week, Changed head & exhaust manifold. Now it wont start, not even a sputter, I checked oil level in HPOP, it's full. I changed CPS with known good spare, still nothing, no smoke. I tried bleeding the oil ports @ the head and oil came out.

I'm really at a loss with this one, any help would be greatly appreciated. I feel like it has to be something stupid I've overlooked.

It's a 96' F250 with only 68,000 miles on it.

OK, charged up Batts over night, keep getting P1212 voltage not at expected level. Cranks over good, rpm on scanner reading around 140. Just no start at all, no smoke, nothing.

Could there be air trapped in the HPOP system somewhere? I changed the pass side head, should I try bleeding the HPOP ports on the drivers side head as well? Since that's where the ICP sensor is?


thanks

Around 20 seconds or so, then I let the starter cool down and try again. Still nothing. I tried Bleeding the drivers side oil system as well.

Got it started! It was a stupid plug in the harness i forgot/missed, over near the glowplg relay area, plug with about 5 wires runbning thru it. I saw it but didn't remember unplugging and dismissed it as the fuel bowl heater I had unpluged years ago. I just found the actual fuel bowl heater line and figured it out.

It's running good now, let it idle for 15 minutes a few times till temp was up at normal range.

It is still starting hard now, takes while of cranking to restart it if it sits for a few minutes? You guys think this is just in need of driving awhile to purge everything?
