Initially, I thought it may have ran out of diesel but I am not sure. It was low and when it stopped, I just climbed down and refueled, then I attempted to start it, no start, check forward & backward pedal, checked to make sure the PTO lever was not on. Nothing...The glow plug light comes on.

Nothing happens when I jump the seat safety switch. In fact I had attempted that maneuver earlier. The glow plug light comes on and the HaZard flashers will com on but nothing else.
Expert:  Wayne replied 5 months ago.

Thank you for that

If you turn the key to ON,

and jump starter

will the engine run ??

Customer: replied 5 months ago.
The engine will not crank at all..
Expert:  Wayne replied 5 months ago.

Hi

If you put battery source to the starter

it must crank over

this by-pass all the safety switches

Customer: replied 5 months ago.
that it does. But the engine will not crank. It just turns over but does not crank.
Expert:  Wayne replied 5 months ago.

OK

So it will crank over but not start

is this correct ??

next on the injection pump is a solenoid 1-2 wire

put a jump wire to this

it will start , Let me know

Customer: replied 5 months ago.
I am unable to proceed further. It has gotten dark here. Ok, let say the injection pump is activated and it starts, Where do I go from there?
Expert:  Wayne replied 5 months ago.

HI

if this all checks out and runs,

a fuse is blown or 1 of the safety is bad

then we need to start and by pass each one

Let me know in the Am
