1996 HR Navigator - HELP

Recommended Posts

Hello everyone. Have a 1996 HR Navigator that I bought a couple of months ago, my first ever MH and I'm loving it.. Everything has been good with it so far until this Sunday 08-11-19, after coming back home from a weekend camping trip, stopped to drop my nephew at his house and waited there about 10 min before heading home. Took off fine from there but then I was getting minimal to no response to the gas pedal. Kept going like that for about half a mile and then it died on me as I was getting ready to enter the highway. Lots of room so pulled into the shoulder and waited a few minutes. Started it again but after 50 ft it died again. Waited another 15 minutes and tried to start it one more time. This time I could feel the response to the gas pedal and decided to put it on reverse and go back 50 ft to tested. It was doing ok so we took our chances and thanks God, was able to drive it home with no more issues. 
Sorry for the long explanation.

So, has anyone had this happen to you; what could be the problem and the fix. I will appreciate any input or suggestions on what to look for. Thank you.

You are going to have to post more info for the gurus. Engine, transmission,etc. Obviously a diesel( mfg and HP needed) and  probably an Allison. Nice looking ride.

I would start by checking fuel filters,  since it mysteriously came back to life, we will all  hope that is a good sign. Congratulations on the new acquisition, glad that your are loving it. Also welcome to the forum.

Navigator, Welcome to the forum. As you just got it and don't know the maintenance history, I would change the fuel filters and add a double dose of Diesel Kleen. Then drive it around locally to see  if it helps.

On the side of the engine (on the fuel injection pump) is this solenoid (photo below) turn the ignition on and watch it move, the next time it acts up go and see if its in the same position or if it partially released.

You can also check it to make sure its not hot, should be warm when energized but I have seen them where they are improperly adjusted or just worn out and get very hot, when that happens they will release and shut the fuel supply off to the engine until they cool. 

As mentioned, starting with the fuel filters is always a good place to begin, check this solenoid while you are in there.

When you remove fuel filters, look for any  black in fuel. If you see black signs in fuel or filters, that indicates there is water in fuel, which allowed bacteria to grow. Biobor fuel treatment is a solution, however it may take replacing the filters several times to catch all the sludge.

BTW, one filter will have a water drain on its bottom. That should be tested for water occasionally  by draining out an ounce or two of liquid. If there is water, it will be plainly visible.

I can't tell you how many I changed when I worked in a fleet shop.  There was a run of a weak design that we went through.

YUP, same here! I also replaced many that were recently replaced due to improper adjustment. When they are energized it must be the same stroke as the lever on the pump. Said another way; the coil will not last if its trying to pull or push the lever farther than it can go. They overheat when not properly adjusted and melt down internally.
