Got a 2004 1500 4.7 liter. Was driving home from work the other morning, started to drop rpms and then died. Threw an obd reader and got a cod for intermittent cam sensor. Replaced cam and crank sensor... Still no joy. Voltages are about 5v to each and no shorts in cables... Have spark to all cylinders and fuel pressure on rail is good 59 psi... Read that battery could be to blame so I swapped it with a known good from neighbors ram... Still no fire... All fuses in box are good... Swapped relays as well all to no avail... Changed the timing chains over Labor Day weekend so I seriously hope that is not the problem though I haven't had a chance to check on the cams and I really don't want to tear the front end back apart to check it on the crank if I don't have too... Was hoping that someone on here would have run into something similar to point me into the right direction... Thanks in advance

 

*update* tried cleaning up the connections on the battery, bottom of fuse box, at pcm... Tried to start it up... Backfired out of intake and blew my air box up... Is this a sure sign that the timing is wrong? I am assuming that it is.
