so I drove in the morning, afternoon wouldn't start. Cranking fine, glow plugs cycled (wipers came on!), turned on manual glow switch, nothing.
Pink wire to IP solenoid makes noise when dis/re-connected.
Fuel squirts out of the square fuel filter bleed port.
0.02v or no voltage between one glow plug and wire during cycling.
In the past few years at least, in the cold, I've had to hold the manual glowing switch (that I installed) and hold the pedal slightly down to keep the engine running until warmed up and white smoke went away after driving a half block with the glow on. Maybe I need new plugs?
This is a 1985 K10 Silverado 6.2L Diesel.
