Engine swap that won't run... need ideas
So I have a 02 jeep wrangler. The PO had put in a 99 4 liter and I blew that one up so I installed a 2006 4 liter that I was told is new and has only 50 miles on it and after internal inspection I have no reason to doubt it. This new motor came complete with all the 06 sensors in it along with all sheet metal and everything it was even sitting on a chrysler crate. So the motor has not been run in about 5 years and I have swapped out all the sensors from the old motor to the new one and all the plugs are connected along with a new clutch and flywheel. Now when I try to start it, it just back fires and acts like its way out of time.... this ran fine last week on the old motor. I pulled the crank sensor to inspect and it seems fine. I plan on buying a new one tomorrow to try it but I'm pretty sure its something else.
Anyone have any ideas. Help would be appreciated.
