I have a 9750 and it intermittently has starting issues. It's not getting any fuel through the injector pump. Seems to me like the fuel cut off, but it's internal on this pump. Sometimes it starts fine and you can kill it and it won't start. Come back and it fires right up. Any ideas?

Check your voltage at fuel solenoid if its even a bit low it wont open up and let fuel past. Had a 9600 that would crank and not start was low voltage to open solenoid.

Have you changed the filter recently? I had a similar problem with our 9860. I replaced the check valve thinking the fuel was bleeding back. Finally I threw on a new filter and now it starts fine again. I think once the filter gets alittle dirty it restricts the flow too much and it won't prime. It may be worth a try.

What year is the machine? 00/01 are mechanical pump with electronic governor and 02/03 are tier 2 HPCR. You would want good fuel supply pressure on either system but as far diagnosing, these systems are very different from each other.

There is a stand pipe with a screen on it in the fuel tank that likes to plug causing the same issues. Take it out and trow it away. Had many soing this and removed the stand pipe and let the lower strainer take out the large pieces.

Fuel strainer is gone. It's an 01. The only open wires going to pump are the fuel temp. Also hasn't had any problems since I posted. I'm definately thinking electrical.

You are not going to like this! I have a 9750 also. If the sediment bowl, or clear plastic filter on right side by the steps is clear and the filters are new at some point it is just not going to start. The problem is in the pump itself. Mine never gave any indication something was wrong. one morning it wouldn't start. it was over a 600.00 to fix it.
