"camshaft position sensor" Easy to test and replace. You have a few ways to determine if the sensor is functioning. One would be to watch the Tachometer when cranking, the other is to back-pin the wire and attach a DMM. Under steady cranking it should be about 7 as the meter reads only the average and not the actual as the CPM is signaling in mili-seconds.
"exhaust backpressure sensor" This "could" have been generated when the vehicle was trying to be restarted.
"misfire rate exceeds emissions" are recorded. When a number in row is exceeded, a code is generated. I have tested vehicles and pulled up the Code 6 Data and seen 15,000 and more logged. No big deal if you don't have other sysptomes.

Check really close for a shorted wire on the CPS, this has happen before. Also open the fuel drain valve and see if you have good pressure coming out the bottom. If all else fails check the fuel heater fuse on some its #30, if blown change it then unplug the fuel heater before starting.
