DownHomeDiesel

A little more than 220,000 on the truck. Previous owners didn’t mention any injector changes. We had to move it across the parking lot. I could have swore I heard a pingy rattle sound coming from the engine area. We are still looking for a local mechanic.

We did make it to Breckinridge but power did seem to dwindle a bit more and when I put it in park it high revved for about 10 seconds this time. Backing in the camper there seemed to be a stutter of some sort. Not knowing the total age of injectors I’ve suggested they get their minds ready to buy new and install before the ride home. We are shopping online but does anyone have a suggestion for a place not too terribly far where we could take the injectors and have them tested and buy new if needed. And/or suggestions on a good mechanic? We don’t have a big arsenal of tools with us. I noticed the 5th nut back on the fuel line coming off the rail is wet. I’m wondering if we could be leaking fuel and/or air there and causing the symptoms also. thanks again for all the help.

Update: stopped for fuel and put it in park. Engine revved a few hundred rpm for about 3 seconds before coming down to correct idle.

Not original owners and not sure on injectors. No tuner or part upgrades except steering components. We just put T-steering and new mopar steering box upgrade on it Wednesday night before having it aligned. sorry, 70mph. It is my dad’s truck so I’m not as familiar with it as I’d like to be. He “feels” it doesn’t have the power it should. Automatic trans. I’ve been watching the oil level for a rise. I can’t smell diesel but it is windy. We are now headed north towards I-25. MPG’s seem to be holding steady. I’ve been thinking weak or leaky injector? Thanks again for helping.

Hey John! This is partially in comparison to a previous trip in the same truck pulling the same camper on the same road at the same speed with lower temps and less headwind this trip than last. We don’t have approx weight of the 5th wheel camper, but truck is 2500 automatic 4WD 3:73 ratio. It has 220,000 miles and we’re on 265/70/17 tires. We calculated mileage based on GPS miles from one fuel station to the next and how many gallons to fill up at the pump, which is how we’ve calculated on previous trips.

We’re in a 2003 pulling a 28’ camper from OK to Breckinridge, CO down I-40 toward Amarillo. Fuel mileage had suddenly dropped to 8.5mpg. Air filter has been checked, new tires are on and truck was just aligned, fairly new fuel filter, valves were recently ran, oil level doesn’t seem to be rising, no noticeable smoke coming out of exhaust, truck isn’t overheating, possibly feels a little weak but still running well. Any suggestions on what the problem might be? Should we find a diesel mechanic or keep driving? Thanks for any help!

It seems like it is the pump itself that is leaking though I can't find a visible problem. Going to try and wire it up later and see if I can get it to leak outside of the truck. I was considering a walbro pump conversion install since I have one lying around. Does anyone have a good, current suggestion for a regulator to pair with it.

So I went out this morning and started my truck. I immediately noticed lots of diesel dripping off the starter and the vent tube. The common denominator seems to be both of those mornings it was below freezing. I guess with it was parked uphill last weekend when it got cold it allowed the lines to empty and thus not starting. Once the engine was warm there was no longer a visible leak. Now to fix it. I I treat my fuel and these other auggestions are at the top of my priority list. I agree. I parked it and drove the 3rd gen I've been working up to sell.

I got called out to work right after postong and have been hooked up since. I'll give an upsate asap. I've started it twice after sitting a few days and it started wothout a hitch.

My fuel gauge is not yet hooked up. I did an alternator and cable job on it a few weeks ago. P1693, P0237, P0382 are codes presently stored. I just tried to start it again and it started fine.

I havent tried to start it again yet. Lift pump is at roughly 60k miles and sings like a song when I bump the starter. 98.5 24v Tank was a little over a quarter tank. I am looking for my code reader. I guess I misplaced it. Will post when I find it.

I have never had my truck give any issues starting. If anything it starts easier/quicker than any diesel I've ever driven. After it sat from Sat eve to Monday afternoon in an uphill position it did not want to start. I pushed in on the clutch and let it roll to a more level surface and this didn't seem to help. Finally after just letting the starter crank for a bit it came to life and drove home without any problems. Little puffs of smoke were coming out while cranking. Any ideas for me to look in to? (Still a stock truck) Some possible things of note: the check engine light is not on but it has come on a few times in the last few months but then went back off again, and I have noticed rarely when I accelerate a brief moment of hesitation.

I called DAP yesterday and put in an order to get the ball rolling. Thanks for the help!

Thanks for the replies. Another question - should I go with the 12 or the 14? How much difference does or what would make me choose one over the other.

So allow me to ask a new question based off of replies. My truck spends most of its time between 500 and 3000 ft elevation (morr on the low side). Again, with a quad and 150hp injectors what single would you guys suggest? Good for towing with a NV4500. Looking around in the more recent forums there seems to be a lot of talk about GXE 57 and SXE 62. I cant find the meaning of "G" and "S."
