Which engine do you have? The 02 or 07? You never said.
Just make sure you always get the correct sensors for the Generation you have.
And please, avoid all the run-on sentences. VERY hard to make sense....

If the motor runs at all, and your wiring harness matched up to the cam and crank sensors in the 2007 motor, it is probably a 24x motor since the truck it came out of was a Classic .

There is no 229 lift. Both those numbers are likely duration.
You might do well to read up on engines in general, then LS engines in particular.

Not being a smart *** at all, but I have to ask... why didn't you install the correct cam sensor and crank sensor from the get go? I must be missing something (wife would agree with that diagnosis!).
