What year is engine? Did you pull codes with a scan tool or the key? Search here "defueling" or "de-fueling" and on google. or with mopar1973man,

Don't wait for CEL. You have to figure out what you have. ECM runs your engine, it is not used for much, If anything, on P-pump. Get the part number off of the current ECM. I can tell which on it is for. Remember ECM is on Block and PCM is on firewall. No, the 01 ECM will nor run the 2000 VP.

 

[bigfish95971]

What year is the block presently in the truck? The PN is on a tag on the ECM, not sure if front or back. It will have PN, SN, idle Voltage, maybe one more thing.

 

[bigfish95971]

Ps. there is no such thing as "limp mode" only some kind of failure or mechanic failure.

 

[bigfish95971]

It sounds a lot like what I have heard defueling sounds like, being right after start that way, but I am not sure cause I have never had it. You can buy a cheap universal OBDII scan tool for under 50 bucks. Did you do the conversion or did you buy the truck that way?

 

[bigfish95971]

That should the correct PN for a 2000, not 99 or 01. 2000 is one that should have and use the crank sensor though. If you have a correctly operating Wait to start light light and no bad ECM code it should be fine. It does not work on a 01-02 block. Pull codes , looking toward a VP.

0216 it failed VP44. That is the death code for failed timing piston in the VP. It will get worse until total failure in short order. Got my last one from O'reilly's with lifetime warranty with a filter change and free fuel swab test provided. From Standard motor parts. list was $1550. No shipping and local or overnight usually. You can work some discounts for price match or veterans etc. Just about anybody can get at least 10% off, price match more. Takes 2-4 hours and only special tool is 10 dollar gear pull disc and if available a 3/4 tubing wrench for injector lines.
I am going steelhead fishing for a few days, will be back to help later in the week.

It is a mechanical failure , not an electrical one.

Where was it purchased? By you? What is fuel pressure? That needs to be know before replacement.

 

[bigfish95971]

Was lift pump removed for P-pump and not put back on. Did you check fuel pressure yet?

 

[bigfish95971]

I think if that is too high for your truck it would cause hard/non start but not sure. Search here for high fuel pressure and VP44 fuel valve or something like that.

 

[bigfish95971]

I do not think it is your problem but It can be . At 20 lb+ or more on some VP's (kind of random) there is a valve in the VP that can shut down. Not really your symptoms I believe. No ore significant increas in heat any where. The the return system is meant to cool the VP purposely. Even at below 14lb there is an amout of return fuel from the VP and injectors in the head.

 

[bigfish95971]

Come on now that is not true. You take any size line and more pressure always increases flow when it is opened up. More pressure creates more flow when open. Try filling a gallon jug from a half inch hose with 40 lb and then where this 80 lb. I guarantee 80 lb will fill faster and shoot farther.
In our trucks 2lb pressure will not supply the VP with enough fuel, 20 would be more than enough. More pressure moves it faster making more volume.

 

[bigfish95971]

The timng piston may be just seizing when cold. Will get worse I bet. 0216 in not wrong that I know of.

 

[bigfish95971]

That is-why I used to like getting mine done locally at a major old injection shop in farm country in Ca. But they wanted to take mine, hold it 3 days and then give me somebody else's core after rebuilding it instead of mine I did not want the 3 day wait for some other core. They were floating cores and not stocking them. So I went to O'reilly's for a new overnight one built by Standard AKA Borg Warner. with lifetime warranty through local store. Bought at $300 off for price match.

 

[bigfish95971]

Damaged o sheared key can cause timing issue but not sure about the warm/cold thing, I imagine the warm cold thin is about the size of mechanical parts when cold vs hot.

some reading and pics.

And you have no codes with the tool?
Search here and google the term Dodge diesel "defueling". Spell different versions.
Contact Moparman1973man either here or on his site. Join his sight if need be. I think he can help.
Sounds like you have defueling by the symptoms but I do not know the answer to fix it. He likely does.

 

[bigfish95971]

He is correct. The 132* I am not sure about but I would guess the VP Timing piston is not responding to some signal from the ECM. Either way 216 is a bad VP. Code is pretty much definitive. last time mine went out it was cold or hot and starting. Lugging up or or load it would lose power and throw the code. Similar the last time before. VP's, even with good fuel pressure usually last 150-250k and the timing piston fails

 

[bigfish95971]

PS, you should always lead with codes if you can. We can let you know if they are usually accurate(and many are) or if there is some other likely underlying source of the problem.

 

[bigfish95971]

That is a common misconception. Codes can be set in an instant. They are stored and most need to be erased and don't go away on their own, often even if repaired and symptoms gone. Some codes will be set to show a problem but no CEL unless the engine is at threat. Sometimes anluther light will trip like the ABS light.
