I have tried to use the troubleshooting books, but have not solved the problem.
Any help would be appreciated. I am all out of ideas.
My M109 multifuel made its first long trip and died when it got home in my driveway.
The fuel pump had stopped making noise a while ago, but the truck ran anyway. There was a reduction in power, but not enough to keep me from driving.
It did run hot (220 and briefly more) going up the mountains on a 90 degree + day.
I removed the fuel tank to change the fuel pump (necessary on an M109) and found the fuse was the fuel pump problem. Replaced fuse and reinstalled the tank. All wires and hoses are connected. Air is now in the fuel line.
The truck cranked well, but did not start.
The fuel shut off valve appears to be working properly.
I removed the fuel line into the Injection pump, there is good fuel flow into the Injection pump, so I know the filters are good.
I removed the fuel return line from the injector closest to the front of the truck and cranked the starter no fuel came out. But I heard a gurgling sound.
I removed a fuel line into an injector, cranked the starter, fuel came out.
I did this with and without my foot on the accelerator. Could not tell if there was any difference in fuel. How much fuel should come out?
There is a small amount of fuel dripping from the Injection pump on the driver’s side.
I can not tell where it is leaking from.
There appears to be no engine oil in the coolant or coolant in the engine oil.
Because it shut itself off I am concerned about the turbo. But I was driving slowly close to home and the fins can be spun by hand with no feeling or resistance. ( I removed the air intake line to check)
The dirty air filter warning is green. I removed the mushroom and looked at the air filter. It is clean.
I opened the air intake hose and sprayed in five seconds or ether. The truck ran on the ether, but did not continue to run.
Please help
