Need some help with 5S, Not a Celica, but still a 5S Options

[d3ath2009]

Recently did some work on my mother-in-law's car. Not a Celica, but a '99 Camry with a 5S so it should be close enough that diagnosis on here may be helpful. I replaced the head gasket, put on new timing belt and water pump, got everything back together and now the car just won't start. At first it would start to hit on ether, but then it eventually quit with that so at this point it may be flooded out, but not entirely sure. I am wonder if its possibly not getting fuel. Timing is good, did it by the book and i checked everything half a dozen times to be sure. It has compression and is also getting spark. Any ideas as to what would cause it not to start and/or how to remedy a possibility of air in the fuel lines? I can hear the fuel pump running after trying to turn the engine a few times, so it should at least be sending fuel up front, but I don't know if its getting to the injectors yet or not. Any ideas would be greatly appreciated and helpful.

it literally sat for 2 days. Day one was tear down, day two was reassemble and it wouldnt start that night. I will have to look into the IAC. We tried no throttle, full throttle, pumping the throttle and results did not change. Pump is supposedly newer, and the fact that i can hear it run lends me to believe that it might be working, but it could've crapped out. Coolant temp sensor did give me issues. Or at least I think thats which one it was. It was a 2 wire plug and the 300k mile, almost 20 year old, brittle wires broke at the base of the connector so I had to make that work in a different way. I think I got it connected well enough that it should work, but maybe i need to order a pigtail. I'll have to try that trick for the injectors, although I bet my wife's old stethoscope would work great for that.
