03 tundra issues please help

So I recently purchased a 2003 tundra ran great and considering the price I couldn't pass the offer up but on to the point I have a 2003 Toyota tundra SR5 V6 with a 3.4 it needed a water pump replacement and so I did the timing marks match back up everything else to me seems to be in correct working order hook it up to a scanner no codes found it'll turn over it'll spit and sputter and act like it's trying to crank but it won't actually run like I said it's got a brand new timing belt water pump all the pulleys fresh spark plugs new fuel filter plenty of gas in it and nothing it's getting spark fuel and ran a compression test on it All six cylinders are holding at roughly anywhere in between 150 to 155 with only four turns of the motor on each cylinder I have worked and worked and worked and worked on this truck and have no idea what else it could be if anybody has any ideas or any help it would be greatly appreciated
