QSX15 hard start/extended crank times w/black smoke

[Rawze]

first of all, assume the old programming is bad + harmful to the engine. More than 90+% pof all de-mandate programming is.

If you still suspect programming as part of the issue, simply copy the file out and email a copy of what someone did in there.

Who knows what kind of progressive damage to the engine and/or turbo may have setting in with the bad delete programming it likely had in it.

======================

next, 559 code IS A VERY SERIOUS FAULT!. If the fuel pump itself is going bad, then it destroys the entire engine with it. It is nothing to ignore.

Someone needs to pull the fuel pump head off and inspect it for damage and/or pitting of the pump crankshaft, and do plunger tests while they are at it.

Those fuel pumps need to be rebuilt every 8,000 hours or 400,000 miles, whichever comes first ... even if they look nice inside, to prevent engine destruction without any warning.


======================

NEXT: Will it pass a proper injector leak-down test at 29,000 PSI? .. to the test exactly as this video shows and see what the leak rate is...
