Truck won't shut off

eyebrowski · 06-13-2010, 09:32 PM

A couple weeks ago my truck started staying on for a couple seconds after I pulled the key out.

Now, the truck will not shut off. I need to stall it out with the clutch to get it to shut down. Although, if I let it idle for ~5 mins it will shut off.

The truck is stock. What could be going wrong?

You need to look at your fuel shutdown solenoid. The linkage may be dirty or in need of lubrication and it is hanging up. That may be why at idle it shuts off after time.

Next time this happens, turn key off and pull the solenoid linkage down to turn the engine off. It is spring loaded to the off position so it should release with little effort. If it releases, you need to clean and lubricate.

If you cannot get it to release (turn off) you may have a more serious problem related to your starter. When the starter solenoid contacts wear they sometime remain in the on or start position. When this happens the starter circuit back feeds the fuel shutdown relay. The relay keeps contant power on the pull on side of the fuel shutdown solenoid. It could burn up your fuel solenoid, wiring, fuel shutdown relay. You need to check this ASAP.

More then likely it is the linkage hanging up. That has happened to my truck.

But, when I first purchased my truck. The engine would not turn off and then it started to smoke and finally turned off. The fuel shutdown circuit had burned up. It was covered under warranty.

A quick check of the solenoid can be done by turniing the key to start and quickly release to the on position. Hopefully the engine will not start. With the key to on, check the fuel solenoid. It should be in the up position. Now try to move it down and see if it releases.

Good info, thank you. I'll look into some of this stuff tonight.

Here is a link for you. The parts you may need are available here. DO get the diode and install as per instructions. It isolates your fuel solenoid from the start system. Keeps it from getting burned if the starter fails. Cheap and easy insurance!!

I found the problem. The hyme joint on the fuel shut off solenoid is rusted and hanging up.

Does anyone know the P/N for this hyme joint?

Sort of doubt the joint is available separately but I see no reason why the old one couldn't be cleaned and lubed up good as new.
If you really need a new one I'd call Larry B.

It was seized on the cam arm and I damaged it getting it off.

I found the correct size on McMaster for $5.47 (P/N 6072K21).

Correction, the shank thread is metric (m6x1.00) not SAE.

Correct P/N: 59935K82

Just had transmission rebuilt in my 04 dodge diesel and now my truck does not shut off and when I turn the key off all the gauges are still powered up. I have to pull fuses to turn truck off any ideas on what my problem could be?

Nope, but I bet the guys on the 3rd gen forum on this site could help you.

My truck did the same thing. My fuel shut off solenoid linkage was sticky at the points of friction. I was told that those solenoids give pretty good service, as I was going off the deep end right away,, and was going to replace it. Try the simple stuff first. I put a little oil on the linkage was all I needed.
