Haven't posted before. Just realized I've been wasting a great resource. Hope I can contribute somehow from now on. I have a 2002 dodge 2500 cummins HO 6 speed 4x4 ref cab long bed, factory leveling kit stock truck, 290k plus miles, no mods. Throwing codes 0500-1693 I live in southern Oklahoma and making a run to the east coast with a trailer. Fixing to leave and Speedo and cruise go out, lift pump quits, never had heat but figure I'll be needing it. So I'm trying to get them all fixed before I go. Heater is probably blocked as both lines are warm going in. fixed some leaks in the air line so doors finally working. Had a lifetime warranty on an autozone lift pump but went to O'Reilly's, got their pump, but fixin to order the FASS DDR-New draw draw-clean tank-mount pump near fuel tank. Main thing is I can't figure out the Speedo. I suspect a bad connection around the ccd or can-bus..Idk. I replaced the sensor on the rear diff. Nothing. Codes 0500 and1693 are only codes. So besides the rear diff, I'm not sure where to look. I've downloaded shop manual, which says there is no vss. Any suggestions would be welcome. Latest thought is add a program that can read and wipe codes, add high idle, improve all around performance. If I can get Speedo fixed that gives me cruise and odometer(fuel gauge never worked, will replace whatever's not working when tank is dropped for draw straw). So, any suggestions on Speedo are appreciated. Is the FASS DDR best way to go? Programmer recommendations? (Never had one...) Thanks in advance to anyone even reads this.

So while my truck is in the body shop i'm sitting back thinking of the things I want to fix or replace on it during this overhaul i'm doing on it. For the past 2 years i've had a psi gauge taped fast to the steering column with electical tape and if i'm dumping this kind of money into a body job, shouldn't I be able to spend some money and get some gauges? There lies the problem ,right now i'm running a Quadzilla XZT module and only gauge I have is fuel psi. I've been wondering if I should go with a 3 pillar set up of fuel, egt and boost, or should I ditch the XZT and buy an Adrenaline with pulse and get the gauges that way. I know, more money then the pillar set up, but I also get the power upgrade with the module. Then I look at the Edge with attitude, only that can't monitor fuel if I understand correctly. Wondering if either programmer will be more than my turbo will take (stock), wonder what other issues i'll have. In my head I kow what the smartest thing to do is..3 pillar and save my clutch and turbo, but i never said I was very smart! I notice the tailpipe is rotted off my truck too, I have a buddy that has a new aftermarket one I can buy for $25 (he went 4"), or I can upgrade to 4" too for about $300, which sounds nice and of course helps work a bit better most likely. Sigh.....to many options, not enough money, to hard to decide Any opinions from people running any of this stuff

with the stock fuel system, i assume best just wait till my lift pump comes but, how much would it hurt to run the fuel save setting? yeh or neh?
