"03 XLT
I have an 03 xlt 4.0 that just died going down the road. Now it will turn over but wont crank and it will constantly backfire out the intake. Have been told everything from the timing chain to the mass airflow sensor. The haynes book says it could be either and I have mechanics that say it cant be. someone plse give me an idea. thank you

Not starting and backfiring out the intake almost always means the timing is off so I would bet timing chain. I don't know how a MAF would cause that, hell I can remove mine and the truck still starts.

open oil cap look down and crank engine see if cam shaft is spinning! Probally the left rear chain is shot down in flames!
