Might be a time to upgrade the 1996 Dodge Ram to something a bit better...

Blown fuse? Bad bulb? Bad socket? Damaged wires? Headlight grounds is in the cab at the driver side kick panel. Not under the hood.

Put +12V power to the brown lead and ground the White lead. The trailer running lights should work. If so the circuit on the trailer is good. Now check the socket where the brown wire would be on the truck. There is a Trailer Relay in the PDC and there should be a fuse also for it as well. Make sure the trailer fuse and the relay are functional.

Our founding fathers didn't work for the government for a pay check they all did it voluntary. No profit made. If our current system went back to that then the voting and out come would be greatly different.

I can give you a clue that Ed (Yankneck696) already has designed a awesome fuel cooler for these trucks that will improve fuel cooling performance. I was suppose to beta test the first series of cooler.... But his Dad died a of a stroke and there was personal issues occurring in the family so he's vanished off the radar for the time being. His design solved a bunch of different issues and had some bonuses too. I wish I could tell more but I can't.

I tend to agree. The whole government system is broken. No matter who you vote for is corrupt. I think the only cure is the Good Lord's Judgement on man... There isn't anyone in the political system I can trust or would vote for to do his/her job. They all talk big during campaign time and then do the opposite when elected...

Still the problem remain for any external cooler has to make contact with the circuit board. Which it can't. This why the whole thing is based on fuel cooling...

I would opt for 80w-90 lubes. Like poor JL_Welding found out the 80w-140 was so thick it wouldn't get out to the bearings fast enough. Even with the differential tipped with a floor jack it took over 30 minutes to even get lube to the end of the axle bearings.

Just to let you all know what still going on. I'm still at home but the fire continues to burn. or... http://inciweb.nwcg.gov/photos/IDPAF/2015-08-14-1651-Teepee-Springs/picts/2015_09_03-13.39.56.584-CDT.jpeg

Funny Idaho has very little sales of Biodiesel. Oregon is B% minimum.

Vulcan Performance is another good provider of injectors. I got Vulcan +50 HP injectors now.

I can tell you Duramax uses a cooler for fuel supply too and I can tell you the location under the truck is poor. The cooler ends up packed with mud and debris so the cooler is worthless. Also make sure to have a thermostat too because the fuel temp gets too cool it will cause the truck to start up backwards. I've seen several reports of home made coolers on VP44's doing this and having 5 or 6 reverse gear and only 1 forward gear. Fuel temperature also affects timing so excessively cold will over advance the timing so warmer fuel tend to retard. Again this why I don't suggest the coolers and not worried about it. If it does run backwards the engine will be ruined in a short time being there is no oil pressure.

Unknown... You might have to poke around a bit I know its there some where.

Most all potato production is down in the south east corner of the state. The famous potato comment is a bit over blown being that there is more wheat grow that potatoes. There is also rape seed (canola oil), barely, hay (alfalfa hay), etc. As for potatoes I've live here on the west side for 25 years and never seen a potato farm yet.

Now that's potato country but not out here on the west side.

That not going to guarantee it to be leak free. As a matter of fact I did exactly that and bought 6 new connector tubes with o-rings. Now number 6 has been slow weeping for a few months. One day I'll deal with it.

They do but mostly in the south part of the state. Most of the west side (where I'm at) is all wheat fields. (Grangeville Idaho)

Cooler will do absolutely nothing As you see there is a air space between the circuit board and the cover and the cover is plastic then the out cover is aluminium. So external coolers don't work at all being you attempt to cool the plastic body and not the circuit that is heated to the temp of the fuel. There is also the possibility the sensor in the pump is bad or off. Like I said there is only be one report of a over heat. I would check with a IR gun. There is more heat in the aluminium body that that plastic cover will do anything about... I still say the PSG is damaged from electrical noise that heat. Which is very possibly how the fuel temp sensor is off because of electrical damage.

As long as the overflow valve is open and fuel pressure is above 14 PSI then your returning to the tank. Then if you keep better than 1/2 tank of fuel then the fuel temperature is typically lower. But temperature related failures tend to alway be pointed at the fuel supply issue which isn't always true. Like most people are shocked to find out a typical summer high temperature is Riggins, ID is 110-115*F like this summer it hit 117*F for one day. So We have the super hot summers here. My injection pump has 201k miles and 9 years old and not had a single problem with extreme heat. I've measure the fuel temp in the tank as high as 140-150*F easy. As for electronic they will withstand huge amounts of heat non-operating. Liked I've left my laptop in the truck on a summer day turned off and it will survive cab temperature no problem. Remove it from the truck and turn it on and allow the fan to cool it down before work with it no problem. Same kind of circuit boards ans solder. Heck the CPU temp of a normal PC can reach well in the 160-180*F under full load. Got to remember the heat soak of the engine can be as high as 190-200*F so I'm sure that used a solder well above the worse heat soak temps. This why I go back to power supply more so. Because if it was temperature related issue we would hear a ton of people losing VP44 in the southern states like Texas and such. Still even in desert states no one is reporting a P0168 codes.

That's normal. There is only one report of anyone setting a... http://articles.mopar1973man.com/2nd-generation-24v-dodge-cummins/59-obdii-error-codes-cummins/155-p0168-decreased-engine-performance-due-to-high-injection-pump-fuel-temperature So I tend to toss the overheating thought out the window. But now AC noise will create heat with the chips and electronics of the PSG causing the same kind of failure. As you pulse a sine wave positive to negative on a 14 volt DC it will create heat on transistors and MOSFETs and create the failure. P0251, P0252 and P0253 is all electronics failures of the MOSFET that controls the fuel pin solenoid. P1688 is a failure of the PSG and not handshaking with the ECM when the key is turned on. All these are power related issues.

Now what I did find the flasher module does have a separate ground and fuse. The flasher ground is the G201 right center dash support. The fuse 10 in the cab fuse panel.

Dave is just plain nuts about Idaho Potatoes. So why not ask your boss to send you out to Idaho to build out here...

Low volt code more than likely the APPS rheostat is wearing out. But typically I just reset the code and see if it returns if so the APPS should be diagnosed a bit deep and most likely changed out.
