Message: [QUOTE="backwoods, post: 884590, member: 4354"] looking for some help, picked up a used F350 cab n chassis 6.4 stick truck last month, 122,000 mile fleet truck, still had DPF and EGR, bought for a work truck, no plans on deleting,, only got a 1,000 miles on it and broke a exhaust rocker, while under valve cover I decided to replace all rockers and valve bridges due to the wear I found, in the process of installing right valve cover I broke the plastic pipe that feeds the heater core, had to remove fan and intake horn/egr valve to replace the broken pipe,,, figured in this far might as well loose the egr n put a small tune in it, got the truck all back together less the delete tunes, truck fired up after a long crank( figured due to having fuel rails empty?) pulled it out of shop to free up a bay and let sit for 2 days, needed to move it and still had a long crank?? decided to put snap on solus on and see what was going on with long crank, first checked codes and all were due to missing EGR components,,( DPF still on truck,, didn't have time to get it off) so I cleared codes and pulled up PIDS to watch rail PSI,, went to crank and no crank???? went to connector at passengers side battery and jumped it and truck cranks but wont start?? pulled starter relay #54 and I can jump across 30 & 87 and it cranks, turn key and power at 86 but no ground at 85?? 85 is a good circuit to 53 at PCM??? could I have killed PCM by clearing codes?? looking for any help on this one [/QUOTE]
