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.

Probably the computer is seeing something like -40 coolant temp and flooding the engine during cranking to start, try holding throttle open fully when cranking to get more air in to offset the overly abundant fuel and see if it'll start eventually. Another tell tale it's flooded is if the oil smells like gas strongly. Fix the coolant temp sensor correctly. I believe an open circuit would cause flooding where as a shorted closed circuit would cause a max temp reading. It's especially confusing because the dash gauge is a different single wire sender.
