Oh Gawd!!! Actually I did... I told him to make the oil just a weebit heavier and hoping it hold together for his trip to Boise and back.

Might be worth checking out your state forum and seeing if there is other family member that might help you out with this issue and turn the wrench for you. http://forum.mopar1973man.com/forums/88-Nation-Wide-Groups As for the lift pump the only way to confirm its dead is to check for fuel pressure and see if the lack of pressure. Like on 24V truck the lift pumps usually still whined but pumped nothing. Usually what happened is the rotor lost connection with the motor shaft because of a cheap piece of plastic glued in the hub. So here we are back to the fuel pressure being a good way of checking to see if its actually pumping.

It would be best to remove the turbo from the truck and remove the compression housing and clean it throughly. Reason why is that compressor wheel is spinning roughly 200,000 RPM's (That's not a typo). So that small amount of dirt and girt on the compressor wheel might chew up the bearings being out of balance possibly.I wouldn't attempt to clean it on the truck too risky spraying cleaners or anything in the intake track that might exploded from the grid heaters or cause a runaway. Just best to remove it and clean it right. As for the rest of the air system its going to be most likely just as dirty so check the tubing and the intercooler inside and see.Hate to say it but K&N filter are not good at all...

Welcome to the family... As for the filter can it will still be full of fuel it will not empty itself. As for the lift pump I would get a replacement pump (not a intank) but a quality pump of some sort. (AirDog, FASS, Raptor, Assasin, Etc.) also get a fuel pressure gauge it will help to protect your investment.

Sad thing is we are 180 miles either North or South to a Dodge dealer that can handle Cummins engines. So it can get expessive quickly just saying dealer.

As long as the gauge is after the last filter you can hook up anywhere in that line. Farther from the injection pump the better it will protect the gauge from water hammer damage which affects both styles electric and mechanical.

He's got a fuel pressure gauge installed and is monitoring the fuel pressure closely. As for the current VP44 he knows its damaged as of right now.

But is it the right pump? Is the pump used maybe? The only way to rule it out is to swap and see...

Solution to this problem has been found... It was the batteries where shot and too weak. I kid you not so far he's reporting to me that all the problems have cleared up and gone away. Except for the the P0216 code which is still there.

Loping is a fuels system issue typically. I would back track all the injectors, cross over tubes, injector lines, etc. Even might have to change the VP44 and see if it changes.

I can pull quite a bit more than just 9 PSI in 1st or 2nd gear...Might check fuel pressure and error codes...

It not my truck with the P0216 code but a gent here locally and the P0216 code is presistant you can clear it drive it a few miles and it right back again. As ofr performance there isn't much for loss but you notice a loss in MPG's a slight loss in power but it will contniue to run.

More than likely you are having issues with the isolator really common. What you need to do is reload it with coolant and rebleed the line again. Also remember to reset the piston too.(Personal opinion)I really don't like the isolators at all. Like in your case the isolator is case of your inaccurate fuel pressure readings. So you'll go the fight to re-setting the isolator and double checking everything. Then if you check the pressure with a different gauge directly connected to the fuel you might find a difference in pressure. I've been direct plumbed now for over 8-9 years and never had a issue with fuel in the cab. Also I'm using air brake line after check out the burst pressure I found out air brake line is rated to 700-900 PSI burst pressure. I hardly doubt 15-20 PSI is going to do it. Also it the same line used on bigger trucks...

Do tell about the data logging? Is it out yet?

If the problem is truely fixed the codes with self erase in 40 warm up cycles. So if you drive the truck for about a month it should be gone. Warm up cycle is defined as going from cold engine below 140*F to over 160*F worth of coolant temperature and then continue to run without setting the codes again. So like I said if the problem is truely fixed it will clear on its own.

Funny you should fine that as a answer. I just got done doing the same thing for a local gent here and replaced his batteries for a dead pedal issue. Strange what a fresh set of batteries will do for starting and performance issues.

Compression test might show a better picture of whats going on... http://articles.mopar1973man.com/general-cummins/34-engine-system/144-compression-testing

Very good video... Nicely done! :thumbup2:Would you be willing to do a full text write up on this?

Too much to go wrong with Auto's...

Bold I'm pretty sure is the correct answer...

So absolutely correct! The only way for you to learn more is to ask questions.

Error codes?If you got to constantly reset the APPS I got a funny feeling your either chasing a failing VP44 or got alternator noise driving the ECM crazy. So check for error codes and then have the alternator tested.

Let me know I'll set you up with the service manual...

with the above posts!

Yes you can run synthetics but you'll fine there is not enough benefits to warrant using synthetics.Like I'm a weird duck with high MPG's (High mark 25.3 MPG) and low drag with all petroleum products. Then like CajFlynn cleared over 1.2 MILLION miles with a 2001 Dodge 2500 towing every day with Chevron Delo 15w-40 and Fleet gaurd filters change oil every 20K miles.Then there was Dorkweed that put on a hell of a show with SuperTech 15w-40 in his 2004 Dodge 2500 and cleared 84K miles on a single oil change. All tested with Blackstone Labs.So after seeing these 2 people do what the did with standard ol' petroleum products I don't believe synthetics are that much more superior to petroluem products.
