Sorry, I didn't realize I did 2 separate posts. Also to clarify. ....I have the M923

So I screw it in clockwise to bypass the fuel pump?

What was wrong with yours? Mine, when you turn the battery switch on the selenoid it activates....the starter switch doesn't activate. I opened the pcb bozlx and the one wire was melted

Bypass fuel pump on m923 Hey, was wondering which way you turn the thumb screw to bypass the fuel pump. I can't remember. Thanks

Which way do you turn the screw to bypass the fuel pump

M939

Also, do I turn the thumb screw clockwise or counter clockwise to set it to the manual fuel system. To bypass the fuel pump

Andyrv6av8r- I see that relay is the continuous one you found. Do they have the other one.....it's a intermittent one

Yeah Napa has each one for 45 and $70. Any ideas where I can find them cheaper or a whole new/used box cheaper?

My PCB is bad in m939. I cut open the box and the one wire was burned out going to the one selenoid. Does anyone know how to tell which solenoids bad and as far as testing them? I was gonna replace the bad one or just the whole box if need be. I can post a pic tomorrow in the light. Thanks...

It's the m923

Ok thanks, appreciate the help.

Where the cable mounts on the fuel pump? I follow that and put it in the opposite position it's in now?

How do you reset emergency fuel shut off. A friend pulled it out, not knowing.

Yeah. There's a round knob that you can turn in to bypass the electric fuel pump so the truck will not run off the fuel pump. I just don't remember the process. If you just turn that round little knob and that's it etc?
