My truck will not turn off? I can put the ignition in the off postion and pull the key out and it is still running. I have pulled fuses and the pump relays and it keeps running. How do I shut it off?

 

Try pushing down on the fuel shut down lever on side of injection pump where the big solenoid is. If that don't work pinch off the fuel line on the fuel filter housing inlet rubber hose. If it's manual trans just put in 4 gear and let clutch out slow. Lugging it down bad too do but in emergency ok.

 

I pushed the rod down and got it to shut off. Sounds like the shutdown solenoid is bad.

 

Its common that the starter contacts stick together , and back feed the solenoid , check that also .

 

Don't assume that shutdown solenoid is bad, check the relay before you spend the money for the solenoid.

If this is the very common $20 problem beware, if you let it run on too long it will burn up your $200 solenoid, melt wiring and can even start a fire.
Learn where the connector to the shutdown solenoid is located and unplug it the next time it runs on. If the engine stops you have an electrical problem. If it keeps on running the problem is physical, like a dirty solenoid or linkage.

If the starter contacts haven't been replaced do so, buy a spare shutdown relay while you're at it.
You can get both for a good price here http://www.fostertruck.com/dodge/default.htm

 

It was the shut down solenoid. Replaced it with a updated one and it's all good now.

 

Can I have your old one?

 

I got lazy when the weather got warm and didn't change my contacts since it started working good again. B/C of this, one day the starter stuck and it almost caught my truck on fire. It fried the starter so I had to buy a new one instead of just being able to put in contacts. Do it now, learn from other's mistakes. My truck would not shut off, so I had to pull the battery cables. Smoke was going everwhere - it smelled so bad and my neighbors were all like WTH is going on? They started coming out of their houses from the horrible noise. Of course during an emergency you can't find the correct tools. I did not know about the relay to pull.

 

My 2500 started clicking from the starter a couple weeks ago.
At first I thought it was the P-N safety switch but decided to drop the starter anyway.
Glad I did, one of the Super Sized Larry B contacts was paper thin, surprised it worked at all. Had 175k miles on it.
I miked the unworn contact and it was barely thinner than a brand new one. Plunger looked fine.
Replaced just the one contact, works fine now and set me back $7.
