Reefer doesn't work?

Sounds like some air was sucked into the fuel system. Now that is running, set it on continues run for a good 5 minutes and keep an eye on it for the rest of the trip.

 

If it's alive and running, set the thing to continuous now. Get fuel asap. That 1/4 tank wont last long.

FIND a shop to take a look at the hard start problem before something else hurts it. Hopefully after you have delivered this one. If it managed to store codes on hard to start or no start attempts the reefer shop should see it.

 

Call your company, tell them you have a failure on the unit and what they want you to do next.

 

Is it starting, then running very slow and rough then shuts itself off or it never starts, rough or otherwise?

It may have gotten bad fuel somewhere and the filters are bad or somebody may have tampered with your fuel supply

Some newer carrier units a year or so ago had an issue that prime would slowly be lost during off cycles and some fuel from near the pump would fall back into the tank, causing difficult starts.

Also could be a bad rpm sensor lying to the main board. This issue may or may not throw a code.

 

And check to make sure the primer pump actuator is closed good (screwed down tight) and you don’t see any fuel leaks up in the engine compartment (even seemingly minor ones)

It should look similar to this

 

Are you loaded right now?

 

Whatever the problem, call your company. Describe the symptoms. Let them decide what to do. If you don't company will blame you for not letting them know & letting them take action. They will rather replace you than pay claim for rejected load. Don't assume responsibility for their faulty equipment.
