caterpillar 3056e no starts

I would agree at this point. Those pumps aren't cheap from a quick Google. Hate to throw good money at it. Guess I'll try tracking down some diagrams and pinouts.

Maybe Nige could find you 1684 Fuel Injection Pump 14: Special Instruction

lol...yeah if it wasn't 0200 for him. Maybe he will see this tomorrow. @Nige

hmm a short wait might save you a lot of aggravation

Patience I got.

And here are the ones for the other three Codes. I may be wrong but I get the impression that low voltage, as discussed earlier, might well be at the heart of all of these.

I found the cure to our issue. we repowered with a Deere 6068

Nige, the SN is 35604554.

Anything special about R&R on these Bosch VP30 pumps? My local people can't rebuild it due to the electronics, but they can bench test it. All things point to the module right now, so off it comes!

Thank you, once again, Nige. I knew about the timing, but not for sure the water pump. I guess it would have been apparent once the job started. The document is valuable.

Bosch VP pumps suck. That's all I have to add.
