Not yet. I've been working on the D250 and the buggy solid this past week. The W250 with the pump issue is still sitting on my trailer. I will pull the pump top this week and look at the governor spring and fulcrum lever.

I did find out that my pump does not fall into the warranty date codes. The link BC posted shows the recall date codes as 163 through 169. My pump is coded 161. I scored a complete VE at a swap meet yesterday. It had black paint over the tag but at $120 I grabbed it anyway. Got it home and uncovered the little ID plate to see what it is. No infinity symbol and the date code is 166. Crap crap...

I've done a top half reseal on the current pump but it started leaking again a month afterward. I'll pay someone professional to do a full rebuild if I keep the VE. That said I am now leaning strongly toward doing a P pump conversion. I don't care about power, I just want reliability. Anymore the VE pump just scares me.

I can get a complete P pump Cummins motor out of a 2nd gen truck for $1500, that is only $500 more than having a VE rebuilt locally. I could swap across all the P pump stuff and have an extra 900 pounds to add to the next Cherokee I scrap. The conversion may be cheaper than a rebuilt VE in the end and I'd never have to worry about leaks and uncontrolled throttle bullitsh again.

I'll post back here as soon as I have the pump top off Jdaivs1.

My pump is a 166.... puts it dead nuts in the center of the warranty code..... hasn't been fixed and no problems so far. Dodge wouldn't warranty it because it was not in the original chassis/body.

Go to the link below and input the last 8 of your VIN to see if there is a recall service that needs done.
Keep in mind, there are some 1991 trucks out there that have a recall out on the steering wheel separation plate.

First off, according to marks link I have an incomplete recall for the injection pump! Sweeeet...if this one dies I have a free replacement on deck.

Second, runaways caused by oil being fed to the engine through the turbo cannot be shut off with the key. Runaways caused by the injection pump might be stoppable with a key if the shutoff pieces didn't get disturbed by whatever caused the runaway.

First off, don't wait on the recall, there is a REASON it's called a "Safety Recall".
This late in the game, Chrysler probably doesn't have the new pumps to satisfy the recall, so you'll likely get a re-man pump, possibly even from a general rebuilder.

Do you realize how truly hard engine oil is to burn in a diesel at normal temps?
Most runaways that happen are due to turbo failure which are at higher temps, where the oil will burn in the cylinder and on a stock engine the destruction isn't usually because of RPMs, but because of oil starvation to the crankshaft, or because a valve got broken due to contact.
An engine can run for many minutes with a leaking turbo and not "come apart", the real damage is done because of lack of lubrication.

Also, in my more recent experience, just because an engine has blow by and burns oil (denoted by a baby-blue hue to the smoke), does not guarantee runaway, either.
I drove a severely worn out 1996 P-pump engine home numerous weeks back, when going down a long grade it would oil smoke horribly when I got onto the fuel, which indicates the engine had oil laying in the cooler and intake, which was blown in by boost.
I was working the engine, since I was also towing a vehicle.
Not even one hint of runaway.

99.9% of all runaways that occur on ve pump engine are due to the pump being turned up too much and causing an injection pump runaway situation

Horus, did you ever get a chance to figure out what happen? I am hoping that I can take my pump lid off this weekend, depends on how my pinched nerve is treating me.

Make sure to either take the pump off GENTLY, so you don't jump teeth. It is very easy to to do, even if you are careful. Might wanna check the kdp, only a few extra hours of headaches...
