Truck is not running right!!!

[Archive]

Went out to start my truck this evening. Waited until the wait to start light went off and she fired right off. The truck did not sound right at idle. The voltage never make it off 8, and the truck would not shut off. So I put it in 5th gear and killed it. Did this same thing about the same time last year, and I had to replace the starter and fuel shut off silinoid. Never a problem until it gets cold outside. I can not figure out what is making the truck do this. but having to replace a starter and fuel silinoid ever winter is not going to happen. can anybody help? I would appraciate it.

Caleb ,

I had the same problem with my truck. I changed the starter and have not had a problem since.

Try switching the starter relay that`s in the Power Distribution Center (black fuse box) under the hood with another relay. You can switch the fuel pump or auto shutdown or AC clutch relays with the Starter relay(if I remember right). Check to make sure it has the same prong configuation. See if it still acts up.

Your Ignition switch could be the problem too. I have not heard of one needing replacing yet though.

My ignition switch on my truck created lots of fun. Sometimes could not shut off truck. Some times it would hold the starter enguaged. Sometimes the radio would not work,and the day before I was going to change the ignition switch it smoked the starter. There is a recall on the ignition switch because it can catch the truck on fire.

I had the recall on the truck fixed about the ingnition switch. This did not seem to help. I just got through taking the shut down silinoid off and it is melted, and the starter was hot. Did the same exact thing last year about this same time. Bill I am not for sure what you are telling me to do. If you don't care could you or someone else try to explain it to me again. Thank you all for your help.

Caleb,

Under the hood on the drivers side fender there is a black box. Unsnap the cover. You will see big "maxi" and "mini" fuses. There are square black relays in it that push into the bottom the box. Look at the label under the cover. This will tell you what relay is for what. Try switching the Starter relay with another. Just pull it out gently. Most should interchange. Make sure the prong pattern is the same. Your owners manual will have a good picture.

Hemi I appracite it. Let me ask you something else. The truck will not even turn over when I hit the starter, but I have lights just like I reguarly do. Can I roll the truck off and it get me home? Thank You!

Caleb,

It won`t hurt anyting to pop start the truck. I`d use 2nd gear.

Starter won`t even engauge? And this is a new starter?

I`m baffled

I`d be looking at your ignition switch. Try switching the relay first. Make sure all your connections on the starter and clean & tight.

Take care

I put the starter on new last year at this time. Then took it off at the start of last week to have it looked at because it was not starting on the first time. When I went to hit the starter it was like the starter was running over but would not catch in the flywheel. When I got it off it was plain to see that the starter was hitting the fly wheel because they was small chips of either the teeth of the starter or the flywheel on the starter. Still can not figure this one out. Guess It will have to go to Dogge as much as I hate to take it to anybody to have it worked on, This has got to be fixed. I thank you for your help

Caleb,

I don't have my service manual handy so this is just a guess. There are two relays on the firewall near the master cylinder. Robert Patton recommended mounting these things upside down a couple of years ago so they would be out of the way for changing the fuel filter. He found out the hard way that water gets into them if you do that. I think one of the relays is for the shutdown solenoid and the other is for the fuel heater. If you got any water in them that could short out the "pull on" circuit for the fuel solenoid and maybe burn it up. I have no idea how that could affect the starter except for running down the batteries. Anyway, please let use know what's wrong when you find out.

From what I have read on this forum I dont believe you can BUMP start these trucks without bypassing something, try a search for kick start or something similar, there have been several discusions on this.
Good Luck

You'll need to turn your key to "Run", then go under the hood and manually lift the fuel shutoff solenoid lever up (and find a way to keep it up) then push or roll start it.

If your truck starts, your solenoid must be working. If you shut the truck off, and it continues to run, you can manually pull the solenoid out to shut down fuel flow. Once the ignition is off, there is no juice going to the magnet in the solenoid to hold it in any longer, and the spring on the plunger should do the rest. If the solenoid can't be shut down manually, you have an electrical problem elsewhere. If you can shut down the fuel manually, look at cleaning the linkage for the solenoid. I ran into a shutdown problem, and the linkage was the culprit. Can't help with the starter. Good luck.

A while back I had my starter solenoid plunger hang up on the contacts. The key was out of the ignition switch and the engine was running with the starter still engaged. All stopped when I unplugged the shutdown solenoid.
It appears that the shutdown solenoid and the starter are connected to the same circuit in some way. Maybe another member can give a more detailed explanation - I just moved and my manual is in a box somewhere. The point is, I believe one electical problem it could affect both those components.

The starter relay sends power to fuel shut off solenoid relay and starter solenoid.
Ground for starter relay is clutch safety switch or neutral saftey switch.
Ignition = starter relay after relay wire splices one wire goes to starer solenoid the other goes to fuel shut off soleniod relay.
The fuel shut off solenoid and its relay have two functions(2-coils) one is start mode the other run mode. The ignition switch controls which mode they are in.
