99 tacoma won't idle after timing belt change.

I just changed the timing belt, radiator, water pump, thermostat, crank and cam sensors. Put her back together and now it won't idle for long. Once I turn it over, it will idle for about 5 seconds and then shut off. It almost sounds like the fuel just shuts off. I plugged in a code reader and I have no codes. It did say number one cylinder is advanced 5 degrees but I don't know if that is as it should be or not. Help me please, I'm at the end of my rope with this one. Thank you all!

Are your Cam and Mass Air Flow Sensors plugged in? no corrosion or anything in those plugs? Also check to make sure engine is getting spark. Typically if the MAF has a break in circuit it will shut the engine off after 5 seconds of running or it wont idle.

MK beat me to my suggestion about the MAF sensor. If the computer doesn’t see airflow it stops the fuel pump.

So, tore it down yesterday because I thought it may have jumped time. This was not so but I noticed the crankshaft timing gear was missing a tooth. I think it broke off while trying to break the crank bolt. Got one on order, won't be here till Monday. I will update once its back together. Thank you for your help!
