Hey guys i have a 1995 12 valve cummins the truck was running great the other day and i got in it yesterday to start it up and my fuel pump didn't kick on but it started so I didn't think anything of it i ended up getting stranded down the road from my house luckily it wasn't to far but i have a toggle switch for my fuel pump under my steering wheel to turn the pump on and its not coming on but funny enough it came on once and i got it home but after i parked it the pump would not come on again. need help guys

 

I would start checking the toggle switch

 

Well im getting power to and from the switch. It also has an air dog fuel system on it

 

How do you know if a fuel shut of solenoid is bad? @https://www.dieselbombers.com/members/gunman41mag.html

 

The fuel shutoff on that truck is for the injection pump. You need to find out how it is wired. The toggle switch should activate a relay that sends power to the airdog, find the relay, make sure it is working. If the relay is working make sure you have power and ground to the airdog at the connector for the pump.

Let me know what you come up with and I can help you from there.
