Questions about ICP

How can I check to see if I need a new ICP sensor?
When I unplug it while truck is running it doesn't die.
Also the connector is wet when I unplugged it. Is this normal?

if the connector is wet, the ICP sensor is leaking internally. Technically speaking, it is time to replace it.

The truck will continue to run, just at a default control pressure level with the ICP sensor unplugged.

I was told yesterday by a local reputable diesel mechanic, that he has seen that sometimes when the ICP goes out, the hot oil leaking thru the sensor can and has burnt the wiring inside the actual harness plug, requiring a replacement of the harness ICP plug itself.

I know that the wire at the ICP plug on mine is soft,,, My ICP had gone out and was leaking trhu.

I may change mine for sanity check if nothing else.

I cleaned the fuel bowl out yesterday. It was caked up with sand, mud, and rust almost up to the fuel heater element. Also the fuel return line had trash in it. I cranked the truck up this morning in 40 degree weather and did fine. Hope I fixed the problem. I will be changing the ICP just for peace of mind.
