Archived 93 won't shut off

[Heetseeker_1]

My friend called me and said his first gen won't shut off. Where is the solenoid and aside from starving air, how can you get it shut down?



Thanks, Steve.

should be a wire plugging into the injection pump on the lower rear end of it. If you strve it use something sturdy like stong plywood. Don't risk injury to you or the truck, mostly you. Turbos are cheap,arms are kinda spendy.

On the side of the inj pump there is a short lever with no cable on it. This is the manual shut off, push towards the back, no more fuel!

The solenoid is on the top rear of the pump, with 1 or 2 wires to it. Sounds like he may have "chipped" the shut off plunger, which lets fuel thru.

The plunger is spring loaded to close if power is lost. If the solenoid windings burn out, the plunger closes and the truck stops. Unless the spring broke, (possible) then there may be metal shavings under the plunger holding it open. Pull the solenoid and plunger carefully and see what you find. If shavings, that is a bad sign as it usually means the pump is taking a long trip south!



If not the solenoid area, may be a major pump malfunction. Has he played around with the fuel screw or grinding the gov. arm inside the pump?

Number one marks the manual fuel cut off. If your standing at the front left wheel looking at the pump... sounds to me like metal shavings might have jammed up the solenoid.



If he has the shavings, the pump is sure to go toes up soon.

Truck won't shut off

I had the same problem with my 1990. The pumps seals were going and some metal was flaking off in the pump. Had to have the pump rebuilt. Hope you solution is less expensive... ... ... ... ... ... ... ... ... ... ... ... ... ..... Blue Dodge

I'll tell him about the info you guys have given me. I sure do appreciate the help, and I know he will too.
