2-105

When using the 2-105 White tractor and in shutting it off while at operating temperature, it will not restart until it cools down. Any suggestions? Use a short shot of ether and fires right up. Don' like to do that, though!
 
Does it have an electric fuel shut off ? If so when the starter is turning over the warm engine it may not be turning the fuel on right away and with the ether it fires and lets the voltage to the pump raise enough to turn it on. next time hook that injection pump to a different 12 volt power supply and see if it starts.
 
Thanks to all replies; more are welcome. Looks like I'm in for an inj. pump rebuild. Doesn't sound cheap!
 

Anticipate that the major head parts of the pump need to be replaced. I got mine rebuilt for under $300.00 but it did not include them and the same problem persists.
 
Sounds like the injection pump hydraulic head/rotor assembly is getting worn enough to leak internally, instead of delivering fuel to the injectors. First shows up as engine will start with a cold pump, but not when hot until it's cooled down again. When it gets really bad it won't start cold either.
Replaced a worn head in a Perkins four cylinder pump a month ago for the same trouble.
 
I had a 4040 Deere that did that. It was the little fuel lift pump on the side of the engine. It wouldn't push the fuel up through the filters,the injector pump had to pull it.
If you're going down the road and slow down to turn in to a driveway,does it flutter a little? That's what that Deere did.
If your 105 is like mine,there's a lever on that pump to hand prime it. If you take a fuel line off,does that lever pump fuel alright?
 
Not restarting until it cools off is a standard symptom of a worn-out injector pump. I had that problem 8-10 years ago on my 1655. (Obviously a different engine). It got increasingly worse over a three year period. The last year someone told me that pouring a gallon of cold water on the pump to cool it down would help. It did help to get it started quicker. But the pump continues to get worse until you rebuild it. My pump had an internal shaft that had to be replaced, which pushed the cost up to $1500. An incentive to get it fixed before it gets any worse inside.
