I have a 2014 Jeep SRT and just finished putting my motor together and fired it up today. My motor started but it's running rough. I checked the codes and the only code is P0016(Crankshaft Position,Cam shaft position Bank 1) The first thing I replaced was my crankshaft sensor since it was easy and relatively cheap but my idle is rough, engine backfires, and is about to die. I checked all my connections(02 sensors, ground wires, etc) are all correct. I checked my timing numerous times when installing my cam and I'm sure its correct. I made sure my pushrods were also installed correctly. What else could be causing my engine to run rough. Is my timing incorrect or a pushrod isn't in place? Is my engine suppose to be this rough and a proper tune will fix this? I removed the wiring harness for my MDS solenoid but was throwing a P0013 so I plugged it back in the camshaft position sensor and now the code is gone. I just hope it's not a timing chain because it's gonna be a PITA to redo. Any help is greatly appreciated!

My motor build
MMX 2618 Forged rods and pistons
Procharged P1SC
MMX push rods 6.775 & 8.050
PSI 1511 springs
6.4L 392 VVT HEMI NSR Performance S/C Camshaft by Modern Muscle
SKU: MMP-NSR-STG3-SC
MDS Delete

Could be a valve train issue (pushrod as you mentioned, or a spring). Feel around the intake runners, if one is hotter than the others that could be an open intake valve.
Otherwise I'd open the valve covers and check for play.

Some of the higher end scantools have a cam to crank relearn function. If you haven't tried that it's worth a go. Since this engine has one central camshaft, if the chain was incorrectly installed it would effect both banks and not just bank 1 (drivers side). So, your problem is narrowed down to what is going wrong with bank 1 that isn't happening with bank 2. You could do compression on bank 1 just to eliminate mechanical from the list. Hope it works out, keep us posted.

So I redid the timing it was a little off. I put everything back together. The car fired up fine and it sounded it was running on all the cylinders but it dies on me. I tried starting the car but barely starts now. It’s throwing a p0016 and P0013 code now. I doubled check my connections and valvetrain. I’m going to guess its tuning related now. Heres a picture of my timing before I put it all back together
