Engine will not start or will not stop
A failed fuel shutoff solenoid holds the fuel off (no start) or will not cut it (no stop). Check power at the plug first.
Engine cuts out
A weak pull-in or hold coil lets the solenoid drop out under vibration and the engine stalls.
Sticking plunger
Dirt and corrosion stop the plunger moving freely. Replacing the solenoid is quicker than freeing an old one.
Fleet spares
A spare solenoid on the van turns a no-start into a quick fix on site.
