Is there an engine monitoring tool available for the 1998 Cummins 6C8.3? This is the mechanical, not electronic engine. What does the ScanGauge D connect to? I cannot find a 6 or 9 pin diagnostic port, only the 12-pin rectangular Allison port.
There is no computer to plug into, so the answer is no.
It's a 12 valve. You just drive them!!!
C8.3 all mechanical engine owners don't need no stinkin' high falootin' engine monitors.
Does it start? YES. Do you have oil pressure? YES. GOOD TO GO! :thumbsup:
If it doesn't start fuel filters or fuel solenoid. If it is the fuel solenoid some hay wire, string
or a tie wrap will get you going.
An engine monitor would help us diagnose the lack of power and the question of whether the tach is displaying accurately, as described in this post from last week: Slow engine warm up (https://www.foreforums.com/index.php?topic=42974.0)
Don't think a monitor would help in that case,maybe for the tach but we already said the tach is off somewhat,no monitor will
detect a clogged air or fuel filter or valves in need of adjustment.Try and do the things we suggested and go from there.
I installed a mechanical gauge for checking the pressure on the hand pump into the primary filter and also a gauge for the discharge side of the secondary filter. Easy to see if the filters have a restriction. It's an electronic engine but these gauges are good for mechanical or electronic engines. See my old posts for location, etc. Will work for Detroit, Cummins or CAT. Won't detect a stuck fuel solenoid but will detect a weak Cummins lift pump.

I use a hand held tach to set the tach on the Dynasty I had. I also lost power and with a gauge
I found I had low fuel pressure which turned out to be a worn out pressure relief valve on the
side of the injection pump.
Along with our mechanical fuel pump swap, we added an electric dash fuel pressure gauge and swapped out fuel return spring-valve on engine-side of mechanical injector pump. We now have a bit more power that would attribute to previously having fuel starvation.
