Constant water in fuel problem
finally caught up to me.

Engine dropped a cylnder,
traced and replaced #2 injector. Opened to inspect vst
coil found no leaks. Bat o-ring expanded
And would no longer seal. Found replacement
O-ring and then high pressure pump failed. Replaced pump
Now starts but sounds awful like only two
cylinders and blue smoke. All static test seem fine as I can hear injectors. Does it sound like other injectors died?
What now?

How long between failures?  All of those things suggest a good fuel system flush, clean the tank, and insure that all hoses, rails, and 10 micron water separator are in good condition.

The next thing would be a DIY injector service as Joe shows in his video, and the ohm and pressure tests would obviously be first to do.

What part number vst pump did you install? Did you perform a compression test?

Remove spark plugs, cut a strip of index card a little more narrow than the spark plug hole. Insert into cylinder trying to angle it in front of the injector. The static test will make the card strip jump and cone out damp with fuel. A stopped up injector will click but not move the strip or get it moist.

Compression test - port 110; starboard 120. Seems within
Range. New vst/ pump 5010819. All plugs spark. Will try index card procedure.

Did you connect the fuel feed inlet and return lines in the correct orientation? They are reversed from the original pump type.

Just checking about spark plug wire
configuration. Too two cylinders use
Too coil; and bottom wires to lower
Coil. Agree?

Yes, each spark plug uses the closest coil.

Engine now running, replaced #2 injector, fuel pump, and plugs. 4 Plugs will not align for indexing which could explain it running a little rich. Cleaned plugged exhaust sensoe.


Diagnostic reports starboard runs hotter then port, attached.

Water in fuel was the culprit due to leaking poly tank. Will
Switch to portable.

Thanks for help

Mike, couldn't open the file but one head always seems to run hotter than the other.
Also the index range for spark plugs is about 90 degrees each side of center of injector and spark plugs have a torque range of about 45 degrees of turn.

Switch the plugs to different holes until they index.
Usually takes a couple extra new ones to get proper index on each hole.
Use the extras as spares and next plug change.

If the non squirting injector measures 2>3 ohms at the connector wires and clicks with the Diagnostics software, worth sending in to an injector service shop for cleaning and testing.  May be just plugged jammed pintle or actuator plunger
