I have a 2004 JCB 210S backhoe loader. The machine starts no problem when it is cold and will run for hours. If we need to turn it off, we cannot get it to restart for at least an hour until it is totally cooled down again. Any ideas on where to troubleshooting the problem.
Be more vague please.
Next time it doesn't want to start when warm, notice if there is any kind of smoke coming out of the exhaust while cranking the engine. That will tell us if it's a fuel problem or not.
Gotta know what inj pump is on that mdl.. Bosch VE Delphi DP300/310 A PFR pump.??
We don't even know if the engine is cranking over at this point.
Almost sounds like an electrical issue on a shut off solenoid that doesn't work when it gets hot. If it is electric clean all the connections. My quad was acting like it had a dead battery then all of a sudden it was fully charged. The battery is in a stupid location under the rear fender and gets covered in mud. I'm sure the mud was causing the problem even though the the bolts holding the cables on were tight and put on good and clean.
Gotta know what pump is on it to find the solenoid..
It would also help to know if it turns over with the starter? If it spins just as fast as when cold? If there is any smoke or "fog" out of the exhaust? Might even help to know how long it's done this, and how the problem developed?
