I have a 2006 ram 1500 mega cab with the 5.7 hemi with no EGR. I bought a junk yard motor and took it to be rebuilt at a machine shop. After I installed it I tried to start it but problem is that it wouldn’t. I checked spark and fuel. Both were good. I checked compression and all cylinders had good compression. Engine just turns over and back fires through the intake. I checked timing and both cam and crank marks lined up. Both position sensors are the same sensors used in old motor and all 16 park plugs are brand new Bosch platinum P/N 6711. I desperately need help!!
