My truck is a stock 2007 5.9 Cummins 2500. Two of my injectors have been replaced under warranty. I have 98,500 miles on my truck. Last year during a vacation trip to the western part of the country I had number 6 go bad and limped into a wonderful dealership in Clarksville, Arkansas who replaced it under warranty the next day.

So.... I will be leaving soon for another 3 week trip to the western states and I want to be prepared if another injector goes out. I will be out of warranty and I know a dealer charges about $1,000 for the injector plus labor. I watched the mechanic replace the one in Clarksville last year and I know I can replace an injector myself.

So I am thinking I need to purchase a spare injector to take on my trip. Does anyone have any thoughts on this? Also where is a good place to buy an injector? I will not have a core to return initially. I need advice.

Thanks,
Bobby

 

Your best bet is to find a "good" fuel injection shop that stocks injectors....new ones at that...don't settle for a reman inj. Most times they are cheaper if you can purchase them through a reputable shop. They should be somewhere between the $350-$400 range.

 

$300-400 plus a core charge of about $100.00

 

Does anyone remember or have a link to the add Cummins was running for factory remanufactured injectors - they came with a 100,000 mile warrenty if I remember right.

 

id say replace all six if you have the means to do so... expensive no doubt, but the best policy you can do for peace of mind

new bosch not remans, usually if one is weak or goes, there wont be another far behind...

 

Have an injector kill test done. That will tell you got over fueling injectors. If so, I would get them replaced as soon as practical. Be sure to get new connecting tubes as well. Replacing them is easy, I got the steps for removal and install as well as torque sequences and limits. One other thing, does your truck make a little white smoke when it sits for more than 5 hours? That's a sign of a shorted solenoid, hence a bad injector. Finding it is real easy. Just need an ohm meter.

 

Thanks for the replies. I decided to not purchase an injector before my trip. My truck turned over 100,000 miles in St Louis. I am from NC and now we are in northern CA and I think I have a weak or leaking injector. The truck runs rough in the morning and I smell more diesel exhaust than normal. The truck runs fine and seems to idle normally when I tow for a bit.

Not sure what I am going to do. I may try to fine a good diesel place on my return trip through South Dakota, Nebraska or Iowa and have the injectors checked/replaced or I may just limp it home.

Does anyone have an opinion whether the injector will suddenly quit working or will it just gradually degrade?

Thanks,
Bobby

 

They can gradually go south but more often than not they just give up the ghost!!! Better start hunting for some new ones on the return trip.

 

I called Dodge and they did not initially say no way to helping me. I have an appointment with the dealer in Beaverton, OR just outside of Portland to do a diagnostic on Thursday and then Dodge will let me know if they will help me.

Thanks,
Bobby

 

www.sourceautomotive.biz is up that way. Great reputation.

 

Chrysler treated me right on six new injectors and Northwest Jeep Chrysler Dodge in Beaverton Oregon was great.

I am writing a blog about our travels and I wrote about our injector experience here: http://bobbystuff.com/Blog/index.php...eavertonOregon

Of all the cars and trucks mostly performance I have owned, I have never heard of so many injector problems till I went to a diesel. Its so disapointing on a expensive heavy duty truck that is suppose to last to have those problems so early.

 

Yeah knowing the cr's require very clean fuel and that Bosch advises 2 micron filtration,you'd think the Big Three would filter the crap out of the fuel on our trucks. I added the GDP 2- micron setup on mine.

Apparently,gasoline must be way cleaner in the US.

After all this,if I start having injector issues,the truck's a gone dog.

 

But gas engines don't run at the same injector pressures today's diesels do.
