I've got a TB180FR, later serial number, 1784****, that randomly shuts off.
Looking at the 4TNV98-ZQTBZ engine, I see a 729938-51320 fuel injection pump, MP4 ECO II.
It doesn't have a stop solenoid like my plain old MP4 pumps.
It has a combined rack actuator/ stop solenoid.
Damned thing will fire up and run long enough to get on the trailer, then it shuts off. To restart, it has to sit for at least 15 minutes. Or not?
Though maybe the tach signal from the alternator was iffy, so, swapped out alternator. No joy.
Any ideas?
Can the rack actuator be swapped without anything special? It does have a tamper screw on one flange?
Can the engine protection be taken offline by placing two terminals together? (Like on my TL150 machines)
I have the early TB180FR shop manual, but, not the later.
Can codes be retrieved if it only has the analog monitor and idiot lights?
