Help with P1689 and P0215
Hey guys,
I need some help. I am trying to resolve P1689 and P0215 DTCs.
Truck: 01 QCLB CTD Auto 4wd. Pertinent upgrades: FASS system 95gph, smartry and original quadzilla adrenaline. There are lots of other upgrades, but none that should relate to my question.
Backround: Truck was sitting for the better part of two years. When I stopped driving it, it was running well. When I came back to start it again, I had a no crank issue that ended up being a bad ignition switch. After that was fixed it will no crank but not start. It has fresh fuel and chraged batteries.No blown fuses or bad relays that I can identify. I checked for codes both on the odo and the smarty and I have a P1689 and a P0215. I had a link in my supply fuel line which I subsequently replaced, but those codes existed before and now after that ( I have read sometimes youll throw a P1689 after opening a fuel line). At this point I found the code diagnostics on this site and began to go through them. As a side note, I believe the VP44 is actually bad. I jumped it and still couldnt get the truck to fire. I do have fuel at the inj pump and the lines are bled etc. There is a secondary issue, and I am not getting voltage to the pump as you will see...
Using Mopar1973Man's DTC walkthroughs, here are the results:

P1689
After going through the first couple of steps, verifying the codes and checking the connectors are secure and there are no visually obvious breaks or problems I moved to step 3 to verify that I was getting voltage to pin 7 (red/grn) wire on the FPCM, I am getting .1v, so no voltage essentially, to pin 7. The guide then directs you to to the P0215 diagnostic.
P0215
1) I have 12.5v to relay 85
2)Relay is good, has 70ohm and was taken from the horn slot which works
3)ECM pins 30 and 49 have 12.5v
4)Relay 86 to ECM pin 36 shows about .3 ohm
5)Relay 86 to ground gives me a reading of between .1 and .5 ohm. It says I should be getting 100 ohm or more.
In the guide it states for #5
"If resistance is less than 100 ohms, repair short to ground in Brown/White wire between PDC and ECM." which seems to be the case.
I am just looking for some reassurance that theres nothing else it could be. I cant understand how I could get a short in the wiring harness just sitting there for and extended time. Has anyone here experienced something like this? I just want to make 100% before I go tearing open the wiring harness. Does anyone have some tips or tricks on how to go about the repair? Would it make sense to tap the brown/white coming out of the pdc and coming out of the ecm connector to verify thats the problem first?
Any insight would be much appreciated!
