If you have spark, gas and good compression, then check your spark plug wire routing again, and your camshaft posistion sensor for propper alignment.

I replaced the spark plugs and all the wire are in the right firing order.

If you have spark and gas, the only thing left is compression, you need to check it, even tho it's newly rebuilt.

I just got done doing the compression test today and these are the results I already know the numbers are not good what I would want to know is why they are so low. On cylinder #1 the highest I got was 90 PSI but on my first 2 attempt they averaged about 30 PSI on the gauge. On cylinder #2 I barely got 20 PSI on 3 attempts. On cylinder #3 they averaged about 170 PSI so did cylinder #4 on 3 attempt. How come 1 and 2 are so low? I know when I crank the engine with the gauge on either cylinder 3 or 4 you can hear the engine crank stronger, but when the gauge is on cylinder 1 or 2 engine's crank sounds more weaker.

You have either a warped head or a blown head gasket, It seems the rebuilders did not check the head for flatness before it was put on! Or the head bolts were not torqued properly. VERY POOR rebuild! Take it back, make them do it right.
