Product Overview
A failed stop solenoid can leave a 6BT/QSB engine cranking without fuel, dropping out of run unexpectedly or continuing to run after key-off.
Replacing the solenoid restores electrical movement of the injection-pump fuel-control linkage once the wiring and relay circuit are confirmed good.
