Truck Wont shut off

[fcdrifter13]

I got home yesterday and had to choke the motor with a anitfreeze jug to get it to shut down. I cycle the key back and all of the cab shuts off like it should but I do not think it is kicking the shut off solenoid, what should I check first, besides the noid itself.

It sounds like the solenoid is sticking....run some transmission fluid or some good quality diesel kleen through it....gently tap it and see if it will close off and shut the truck down.

if it wont shut off--see if the solenoid wire to the pump stays hot when you shut it off--if so--FIND OUT WHY--------

Yes... Do the above and find out why this is happening... It could be the ignition switch has failed. If it has the next thing you may see is an electrical fire under the dash. This switch did cause several wireing fires prompting a massive recall years ago.

Pull the big connection off on your ip, while the truck is on. Its the one with two wires

Well I was looking at it this morning and found another problem, since the truck has not be shutting off, the glow plgs will not kick on either unless I pul the fuse under the hood and put it back in.

I kinda thought the one with the two wires was for the timing advance, because the other wire branches off to the fast idle solenoid.
I Dont have my truck close by to double check.

No that gives the pump 12v. When I had no keys i ran a switch to the battery and that big connection to turn it on and off.

That didnt work, so I think I have compund problem of both the switch and the noid sticking

If the truck stays running without power (you have pulled off the wire), it is at least the solenoid being stuck open. Fix that first. Chances are that everything else is OK.

thats one good thing about having an electric pump, you unplug it (or wire a shut off switch) from power no more fuel. with the mechanical pump you have to choke it.
