Welcome to the ForeForum.

Do you mean a KING CONTROL Cruise?

What year/model coach do you have?

King Control throttle AND cruise or air throttle and King Control Cruise?

Download their diagnostic chart and you will likely find a simple problem.

King Cruise is a reliable throttle & cruise control system.

They support the product and have some good troubleshooting documents on their web site.

Who took it out and put back after rebuild? Even checking, unplugging and re-plugging the many connectors could solve your problem. Make sure no single wires have pulled out of the back of the plugs.

Did you look under the bed, maybe the pull cable disconnected.

I just shipped my throttle/ cruise unit to Cruise King today to have it looked at. We put a control board in it last summer but have had intermittent failure still. Good people at Cruise King and I hope after sending the unit itself to them we can be done with the issues.. You ask is there anything else you can use.. James at Foretravel suggested months back that I let them install a air throttle/cruise unit.. I was down there 2 weeks ago and James wasn't there and no one in parts or even the service manager had ever heard of such a system so I have no answer to your question..

I had my control rebuilt by King Control rebuilt by them a few years back and it worked great. Check with them and they will help you
trouble shoot it with you. It could be your foot peddle control and I had my brake lights come on and you can only 1/3 throttle when
that happens.
 

FYI
Carry a long rope, and a stick. Trust me.
When bringing a coach back from the San Diego FT store, to the Liberty lake store, had one quit in rush hour at the hwy 60/10/57 intersection in Pomona California, while in the fast lane.
3 of us relayed to the other.I worked the throttle by hand in the engine box, my son stood half way in the hallway telling me what the driver wanted.
As soon as we got off the freeway, it started working, worked all the way home 1200 miles.
Go Figure

Could be issue in harness connection

Hou may want to rule this out.  Mine was rebuilt but that wasn't the issue.

Intermittent power 97 270 KC2600 not fuel (http://www.foreforums.com/index.php?topic=32410.0)

When my King Control was out for repair I used mechanics wire and and latched it to my brake peddle and the throttle arm on
the engine and it worked great. The only thing that wasn't prefect was the trans didn't shift properly but was good enough. I use
wire as string would stretch to much so wouldn't work with the throttle peddle. 

Here is some info on dealing with C-8.3 injector pump throttle and King Control:

King Control Throttle and Cruise Control Issues (http://beamalarm.com/Documents/king_control_throttle_and_cruise_control_issues.html)

As a test or to travel without a working King Throttle, we and others have rigged up a cable to manually move the injector throttle bracket.

One time for a short distance, with bed up and a 2-way radio with directions from Cindy driving, I pulled up on bracket to give her throttle.

Another time needing to drive a long distance, made a wood hinged foot throttle for the driver's foot pull a long cable that was fed through the front of the bed. Both manual throttles worked just fine and quite safely got us to our destinations.

Another (perhaps safer) approach is to have 2' of 1/2 to 3/4" ID PVC pipe and some no-stretch line/rope.

With bed open, route the line/rope through the PVC. Close the bed with the PVC in the closure to insure a friction-free exit forward. Stuff rags or foam in the rest of the opening to minimize fumes into the coach.

IMO, one person operating the (manual) throttle and brake is safer than two or three.

Brett, we followed your description on a an alternative "drive by wire" solution.

We drilled a low hole in the front of the bed and a matching hole facing the engine compartment, then ran a copper wire from injector pump throttle swivel controller, through the drilled holes to the front of the motorhome. Built a hinged foot throttle pedal, mounted wire to pedal that kept the wire taught so any pressure on the wood throttle raised engine RPM. We drove with normal highway speeds over a long distance over a couple of days with only the driver in control, with solution that felt 'normal'.  Foot pedal made things go faster.

Copper wired was used to eliminate any stretch in the long pull cable.  And we were aware of our total distance that needed to be covered, so we took the time to build it.

Maybe I need to pack some non stretch 100# test aramid fiber fishing line (FireWire) from Walmart for such an occasion. Might be handy for other stuff also, including fishing.
