DO NOT USE ETHER! THE GRID HEATER WILL IGNITE IT!

The most common thing to cause a crank-but-no-start condition is the fuel shut-off solenoid on top of the rear of the injection pump. It needs 12 volts for the engine to run. You can get some fuel at the injectors even if the solenoid is closed, just not enough to run.

After a year, the plunger in the solenoid might even be varnished in the down position.

What he says about grid heaters igniting ether is true. Disable grid heaters first.

you shouldn't use either, at john deer school they said to use dry silicon spray, said it was easyer on the engine.... just my two cents

What the heck is dry silicon spray?

Ether isn't "good" to use on any engine, but sometimes... You just gotta do... What you gotta do. And that can involve the ether bunny.

Sounds like its time for a compression check.

wouldnt low compression cause it to spin faster, ipulled the injecters it still spins the same.could the injecter pump be bad causing it to spin slower?
