Ok so here is a picture of the ve on my truck but my question is what is this on it?

It is the little round pice with the wire connected to it with the metal tab on it?

 

The little round thingy in the middle of the frame is the fuel shutoff solenoid. It should have +12v on the terminal with the key on and 0 when it's off.

 

So the truck won’t turn over at all it just cranks and cranks I will check and see if it has 12 volts with the key on, would some one happen to have a part number I don’t know what is the long one down lower in the left of the picture

 

Ok after getting home I was able to test it with a voltage tester and I am getting 11.6 volts to the tab I know it’s not 12 so what are my next options?

 

You can take it out and inspect the plunger on the end. If it looks ok, you can remove it, reinstall the solenoid in the pump and start the truck. You will have to use the shut down lever to kill the engine.

 

If you do replace it, used to be the VW part was cheaper than Cummins and they are interchangeable.

 

I found the v w part number so
will this little thing cause the truck not to start also?

 

Well its called a fuel shut off solenoid for a reason.....

Provided you have a good fuel supply and no internal issues in the pump, that solenoid could fail and leave you with a no start situation.

You could just run a jumper wire from the battery positive to the solenoid and crank it, if you feel your factory harness is questionable.

You don't even need that to start and run. Quite a few members here (myself included) have changed over to the manual shut off cable.

Do a search for fuel shut off solenoid in the 1st gen forums, there is lots of good info in old threads.

 

If you jump it with 12 Volts it should click ken

 

I tried jumping it straight from the battery and you can here it click along with do everything else sounds like it’s on the fender or something tried to start the truck after that it ran for 30 seconds then shut back down and now all it will do is crank so going to try and remove this to see if the truck runs

 

When you remove it there is a plunger and spring that you will remove from it then screw it back in, if it runs fine after that then the solenoid is bad and either replace it or just rig a pull cable to the manual shut down lever

 

If it still don’t start what should I consider next

 

I see in your other thread that you are having problems with your lift pump, have you verified that it is working?

 

I took the positive from the air dog ran a wire out and around the truck and touched it directly to the positive on the battery and boom it turned on so that not my issue I also just ordered a set of guages and a gauge pod so waiting for that to get here I removed that little black plunger had my dad touch the wire from the fuel pump as I turned the key and hoop start up repeat his process 5 times and it worked every time so I believe I need to order that solenoid,

 

Ok not really following you on that, so you removed the plunger (gutted it) then put the gutted solenoid back in and it starts and runs fine?
