Well after getting the Vulcan Performance test gauge and hooking it up we found this truck only has a mere 5 PSI at idle. Now rev the engint to 2k and you can pull it down to zero without even putting it into gear. New in-tank fuel pump will be hear in the morning. All I can say is these thing are a PITA to deal with. We did the bed lift idea and man that's a PITA too. All the rusted bolts in the bed. All the stuck and hung up connectors on the tail lights. As for installing it does make it easy being the tank it full of fuel better than pumping the tank out.

Uh Oh?! Did you mess with the voltage setting of the APPS sensor? If so it will cause issues. http://articles.mopar1973man.com/2nd-generation-24v-dodge-cummins/26-engine-systems/37-apps-sensor-voltage-adjustment

If need be you could unhook the cable for temporary time so you can drive. Remember the shift pattern will be goofy without it.

Actually I know the reason on that it was a BoD decision to limit non-donating member to the tech topics. So once your donation lapsed your account rolled back to normal member and the forum s became off limits.

It should be ZERO after the lift pump cycles. 5 PSI means there is something wrong with your gauge. I would be considering checking your gauge for accuracy. 14-20 PSI is suggest and the lowest you should see is 14 PSI at a WOT stand. 10 PSI is the book minimum but risky...

This picture will look like the tip is touching the bottom of the tank but it not. There is a gap the thickness of a quarter coin between the tip and the tank bottom. As for the tip you'll see I lightly notched the tip with a grinder disc so it can hold suction to the bottom. The fuel in the picture is just a quart. As you can see it still covering the tip but this is the only bit of fuel the AirDog 150 couldn't pick up.

Here is a eye opener for the stock gauge...

How are you checking oil pressure with a external gauge or with the cluster gauge?

Error codes and fuel pressure? Tapping the VP44 with a hammer is not a good sign.

Sound like someone cut the tube too short. Another thing I see is people cutting weird angle cuts on the tip which causes this too. Straight cut and it should be the thickness of a quarter (coin) from the tip to the bottom of the tank on a empty tank. As the tank fills the bottom deflects away from the tip (about 6 pound per gallon).

??? Really digital sounding doesn't sound bad that I can tell. Just super loud exhaust.

Not exactly. Like the 95 I got here starts super easy to start and has the spit and sputter on the top end. Once the system clears the air its gone. Run beautiful the rest of the day. I've got some other bench testing to do for it too.

Typically that a sign of other issues wheel wise when end up with scattered weights. It could have excessive run-out or other issues. Higher the speed more precision is required.

Most likely not. I've seen from the outside what death wobble is. It a balancing problem or shock problem. I've been along side a Dodge on a motorcycle and watched in super close up mode of the axle jumping off the pavement and a tire nearly making contact with the fender as it oscillates in a circular motion. The vehicle has to slow down to nearly like 30-35 MPH before the violent oscillation stops. More that likely the death wobble is going to be a rotational mass that is out of balance typically a tire(s).

Air in the fuel? Hook up a clear line and loop it on the windshield and see if there is any air or foam being generated. I'm fighting that problem now on the 1995 in my yard. Losing prime and rough starting. What I've done is grease the fittings on the AirDog and it made a temporary improvement.

When I've got a disabled 05 Dodge stilling in the yard and its not capable of producing enough rail pressure to making highway speed you might as well buy some tools to diagnose this issue. Funny how working for 2 local shop and doing a delete for a local person has gotten the word out that I work on Dodge Cummins trucks. I've got enough work for this winter right now. Just with one customer I've got 5 different jobs to do. Then with the 05 Dodge his cousin owns a Dodge Cummins as well he want me to do KDP and some other stuff too. So more or less the word of mouth is getting around.

Yeah... I just got more tools added to my collection I just bought a fuel pressure test gauge for low pressure side. I pick that up from Vulcan Performance. Its a wonderful 0-30 PSI oil filled test gauge that should work for most all diesel applications. Then I got me a test cap for common rail fuel systems from Geno's Garage. So now I can systematically block off each injector testing for bad injectors on common rail engines. Funny how your tool box continues to grow no matter what.

Well in your case might not be then but still wheel balance can be a factor still. Is the tire true round no blisters or such? You'll be able to see it on the tire balancer if so. Shocks would be my next step.

Interesting not on that page... Dynamic Cranking Pressure: (at 150 rpm starter rpm) Note=> after 7 to 10 needle pulses on a hi-quality Compression Tester The slower the cranking RPM, the lower the cranking psi The faster the cranking RPM, the higher the cranking psi The poorer the Piston Ring seal, the lower the cranking psi The poorer the Valve Seat (and guide) seal, the lower the cranking psi In addition, aluminum Blocks may show lower cranking psi Also Engine should be between 140 F to 180 F temperature for Tests The compression tester's needle should swing over to 90+ or more psi on the 1st Pulse this indicates great Hone Job, Valve Guides, and Valve Job

I've got a degree from ITT Tech for electronics and computer science. Yeah I know...

That where over size tire users have some of the issues. With larger diameter tires and wider faces it takes so little to be out of balance that death wobble does occur. I've seem some with huge amounts of weights plastered to the wheel trying to obtain balance. Then when the do hit a bump or bridge seam then the death wobble starts. This is because of the geometry of the tire and the out of balance can be so small that the leverage angle of the weight is greater that factory sized tire. Not to mention factory sized tire weight much less in rotational weight. All play a roll in the death wobble problems.

I would say it a air in the fuel. Some where you have a suction air leak into the system. The high rev misfire and the bluish smoke is most likely air.

The only time mine doesn't get plugged in if outside is when there is no electricity to plug into. Darn "Current Bushes" don't work very good up here in the middle of winter. Typically I make sure to get it at least parked in a unheated shop which is typically above freezing not but much though.

Still can use it. Use a 5 pin relay. Then use 30 and 87 pins leave 87a open. The when toggled to low the circuit open and the light are off.

Simple get you feed from the fog lamp relay.
