P0340 & P1391 Error Codes, no start sometimes
Well, I have a 99 5.9L Durango that has been running just fine, but the check engine light came on recently. I pulled the mentioned codes with my OBD reader, and have been looking to fix them. Just the other day, the truck would not start, just kept turning over until it seemed like the battery went dead. Well, i jumped the truck, and it seemed to run fine, but I did a load test on the battery when I got home (ok, but on the weaker side), and researched the codes again on this forum, and decided to get a new battery. Did that, cleared the codes, and all was fine, for a bit....a couple of days later, again, it didn't want to start right away, but it eventually did after about 6-8 tries. Check engine light came on again, but has been starting right away. I have checked local auto part stores for a new cam position sensor, but everybody (Kragen, Napa, AutoZone) says they don't carry it. Kragen did say they have a "pickup coil" instead, which is located in the distributor. Should I start with this sensor first, or should I do this AND the crank position sensor as well? Any additional tests I can do to pinpoint my issue, so I don't spend time and money I don't have on all these sensors? Thanks in advance!
