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.

Update: It lives!! thanks for all the help. Issue turned out to be timing. Thought I had everything in time, but when i turned the crank to take the slack out of the belt, I was jumping it ahead about 5 degrees. Temp gauge is still hit and miss though. one night it read right about mid-range the whole 15 mile drive (even after sitting at idle for half an hour) and the next it decided to read up near the hot mark after just a couple of miles. Temp would go back down to mid almost instantaneously if I made the car downshift or just upped the RPMs revving in neutral. Wondering if that sensor is bad and may have been the real problem the whole time. (Although I'm sure timing belt and water pump needed changing anyway just due to the miles on it)
