I have a 2015 CAT 259D FTL03107. The landscaper was using it behind my house to move some cobble rock. He shut it off to talk to the workers. Got back in it 10 minutes later...it cranked strong but wouldn't start. Never started ever again. Plenty of fuel, filters clean, water separator full, primer pump runs with key on for 30 sec or so (I just changed that primer pump this year), no clue.
I called Michigan CAT for field service (the 259 is in a steep backyard and basically inaccessible to remove from the premises without some major heavy equipment and winches etc.). The tech arrived last Tuesday morning. After a full day of diagnosis, I was told it needed a high-pressure fuel pump. The part was $1791. Since Wednesday, the tech arrives at 8 AM and works until 3p in dismantling the engine/chassis to try to get to the pump. He said he might have it done in another 1-2 days.
Has anyone replaced these pumps? The CAT has 700 hours on it. I don't understand how it could fail after the machine was shut off. The tech had many interactions with the CAT service operations center and they told him it needed the pump. BTW, he did try swapping the electric solenoid valve first but no success.
Also, there are no faults from the CAT computer, nothing awry displaying on the screen inside.
