Funny, after I posted this someone bought a set of diodes...

Geez if you guys have you pin updated on the map it would be child's play to find each other... https://mopar1973man.com/membermap/

Just like the hugely overpriced Cummins thermostats...

In other words, the ECM did NOT boot up at all. As long as the Wait To Start light never comes on the software never booted so it will not start. Our ECM's boot up like a normal PC. It's got a BIOS (Basic Input Output System) that tells the storage EPROM to load the software up and then the first instruction is to light the Wait To Start light and check for grid heaters needed or not. If you never get this VP44 will never power up. Typical killer is excessive AC noise from the alternator. Most people do some wild ideas attempting to mask the problem but never fix the problem which is fried alternator diodes. Hence why we sell the diodes here on the site for repairing the alternator. Then Dodge screwed the pooch on the electrical as @W-T will point out.

Finally got most of my logs typed in. Here is the 2002 Cummins with nearly 2 years of fuel logs typed in. Here is the 1996 Dodge 1500 with nearly 3 years of logs. (Much less data... LOL)

Well gang... I might just retire the old method of written hand logs and finally move up to an electronics means of logging fuel and maintenance on the trucks. I found an app named Simply Auto for Android. https://play.google.com/store/apps/details?id=mrigapps.andriod.fuelcons&hl=en_US The part I like about it is that is for the $4 dollars you can have 3 different drivers/devices adding to the logs. For example, if you have your phone on you and you add fuel to the vehicle your wife/girlfriend device/phone will be updated as well. If she now takes the vehicle and has an oil change done she can update the app and you'll know the task has been done. Then you have all your data on the cloud and never have to worry about losing your information. I went ahead and inputted all my logs for the 1996 Dodge 1500 and then went over to the web page and logged in and you can see my data for the 1996 Dodge 1500 truck now. Nice to see my last tank of fuel I hit 17.05 MPG. As you page through all the data provided you'll find out there is a ton of different things this app can do. You can even log trips for mileage for medical or for tax reasons or for reimbursement. You can make all your maintenance logs custom values for anything you wish time wise, mileage or both (which ever happens first).

Yeah, being I was the one with the fire this summer. You be careful and safe. Hide the Cummins somewhere safe. If it was me I would be driving inland more for a night or two for safety being your on the road for now. Hopefully your Wife and family will be safe.

Got to be nice with these hoses even if they are stainless steel braid. If it's in my way to fully remove the entire hose from the engine. Then when I reinstall I put it right back with the same curve in the same position again not to flex on the hose too much. This includes the turbo supply line too.

On the flip side, I've got the AirDog 150 which I purchased back in 2006. The first pump head lasted 13 years and 250k miles. I'm on my second pump head now and no problems at all. Filters are going 60k miles a cycle and pressure are really stable at 15-17 PSI all the time including illegal speeds up to 100 MPH. Never drops. Then I've still got my stock fuel filter housing and its not a restriction at all. It's a bonus being that all fuel is double filtered before consumed but the VP44 and injectors. Even my VP44 lasted 243k miles before failing with a P0216 code where the timing was stuck at full advancement.

Simple solution. Build a tune that has a less aggressive fuel curve and then make it 7 levels. This way you can float on level 4 which would be 25% wiretap. Then I would set the wiretap for only 1200us pulse. You could just drop to level 3 and be strictly CANBus fuel and not even worry about it.

Challenge accepted...

Now since I changed to 245s tires I'm shifting up at 1,500 to 1,700 RPMs easy. I'm in 4th gear by 25 MPH and in 5th gear by 35 MPH... NV4500 transmission.

Stock it would float about 18-19 MPG. Edge Comp is where I started my study of the IAT and that was back when I hit the ball out of the park at 27.2 MPG hand math. Now on the Quadzilla but new injectors, different turbo, new VP44, etc. Now I'm now starting to rise up to 19-21 MPG. fairly constant. Basically in a nutshell. IAT wise the temperature offset is roughly 30-40*F over outside temperature. This value applies to both my trucks 1996 Dodge 1500 5.9L V8 gas engine and the 2002 Dodge 2500 5.9L Cummins.

Take notice to the 1/2" pipe plug. Right between the MAP and IAT sensors. Guess what? That is a coolant passage. This is why I started studying the 180*F thermostat instead of trying to move the sensor. Being moving the sensor isn't going to help. Being the 180*F seems to trim off about -10*F been the coolant temperature is lower.

Ummm... I still got the old school ball and spring. No adjustable regulator. When I changed the pump I only changed the pump head!

Darn EPA and smog test places looking for error codes.

Don't do this it will create issues with error codes from IAT not sensing grid heater temp change. Yeah, there is a grid heater error code on some years. The other thing is the cooler temp fouls the timing tables for the stock truck when you move the IAT. The IAT can't be moved it does make an effect in timing and degrades performance typically. Remember my MPG fooler fools for 143*F of IAT and some gains are found there for MPG's. Making this cooler or allowing to drop below 80*F will make the ECM kick in nearly +3 to +4 degrees of timing on top. Cooler IAT temps is not a solution... Hence why my produce came into existence... So, moving the sensor is not an option. Just for fun my 1996 Dodge 1500 V8 5.9L has much HIGHER IAT temps than the Cummins. It can range as high as 170*F with heat soak. All cold air intake is in place too. The funny part is the very same sensor is used. I'm even running a 180*F thermostat now from the stock 190*F.

Technically I should be in the same game as you now with pump heads we will see what shakes out. Being you have the adjustable regulator you might look into checking the regulator and see if there are any problems with it. Hanging parts, worn parts, etc.

Dodge Offroad is slow to getting parts out from what I understand everything is built per order basis and takes time. If it wasn't for your lift you could follow me. I've got a high mileage success rate for all suspension with 300k or on tie rods, heading for 200k for ball joints, track bars are well in the 150k mile range. Most don't want to follow me because the secret is the smaller tires and wheels I'm using and no lift or leveling.

Then there are lucky ones like me. 13 years on the first one. Now heading out on my second pump head from AirDog. The only thing I've got a random problem with is pressure I know the problem is the way I bent the spring so the ball gets hung up where it can't close completely and the presssure falls lower than typical. After a bit the ball finds its center again and pressure stay ay 17 PSI.

I thought the same thing as well... I didn't know of anyone able to get new pump bodies.

That worse case scenario. Valves, guides, seal, check for true, etc. Already got leaking valve seal now. Guides? Won't know till he can look at it. My first problem is getting the head off and letting a shop look it over. The shop I'm dealing with deals with mostly Cummins engines.

I'll most likely replace mine with new one being the number of miles I put down per year. I really don't want to do this job twice in the same year.
