P0340 5.9 engine
I have similar problem. Engine does not stall but when at full running temp engine intermittently will not restart when shut off. At this time is when I get the code. The problem is happening more and more frequently. I have a ODBII tester and clearing code rarely helps it start. I have also noticed that It tries to fire for a second just as key is turned, then it seen turnover without resistance. It always starts after full cool down with or without code cleared.
I am going to try distributor pickup (Sensor) as first try.
I have question about the variant tolerance in PCM for cam to crack position. My vehicle has 190K + miles and expect that slop in timing chain could push variant past tolerance for PCM. This may explain why it always starts in the PCM's close loop mode.

Different sensor connections
So I recently put a motor from an automatic into my 98 1500 with manual transmission. During the swap I noticed almost all the sensor connections were different between the two harnesses. Why dodge decided to make them different between the manual and auto is beyond me. I ran into the same issue with the cam position sensor. The black one is for and auto and the grey one is for the manual

2002 dodge 1500 motor swap pulling hair out
Just put a used 4.7 in dodge 1500 pulled from 2002 durango both seem same had durango running before pulling. original 1500 motor was cooked. Got p1391 and 340 codes does the computer have to relearn or flashed for engine swap. Ive got new sensors coming crank and cam . It acts like it wants to fire checked cam sensor got 5 ohms
