Dave,

I have an NHC 250 in my M816 wrecker. It has the glow plug and spray
nozzle arrangement. I was having trouble getting it to start. I figured
that it was because I didn't use it all that often. Had to use ether to
start it every time. One day, it wouldn't start at all. No way, no how.
It turned out that the fuel shut-off solenoid actuated valve had finally
quit on me. It could be by-passed by turning the little knurled knob on
it, but that was also how you had to shut the engine off, afterward. You
could look and see if your engine has this knob on the shut off
solenoid. If it does, try using it to bypass the solenoid first thing in
the morning. If the engine fires right up, your shut-off solenoid is
probably going bad. Worth a try, and easy too.

Guys,

I have an NHC 250 engine in a civilian truck - it requires either to get
it started even when it is warm outside. It does not have glow plugs.
It had an ether quick start kit installed on it when I got it. The
military NHC 250s seem to have a preheater installed on them with a glow
plug and a spray nozzle of some sort in the intake manifold.

Is it normal to have to ether these engines even when it is warm outside
- like 70 degrees? Once I get the engine running - even if I shut it
off for a couple of hours - it will easily restart. But ether is
required the first time each day. Not a lot, just a one second spray in
the top of the stack.

The engine runs well - no smoking at all. And that is without a turbo.

Dave
