I have a HDJ100 that blows smoke on cold starts since I got it. White-ish, smells of unburnt diesel. Clears up 7-8-10 seconds after starting. Isn't visible at all above 18C (~65F) and gets pretty thick below 0C (32F).
Just got the injectors tested - perfect spray and pressures.
Seems to be a problem with the intake heater.
Never had the heater light come up on the dashboar before, but after the recent servicing (intake assembly clean up, injectors tested, other minor things) it appears very briefly (about a second). It's cold enough - single digits C, so it should come up. Heater was tested with direct 12V - heats. Would have checked resistance, but the FSM does not give an expected value. Heater relay seems to work as expected.
What should I check next? Which temperature sensor does it use to determine if it should be on or off?
Can it also be the pump? I couldn't get it checked, as none of the diesel specialist I have contacted in the entire country (!) wants to touch the FTE pump.
I don't have any other complaints. Runs smooth, no atypical noises or knocks, no smoke once started, no noticeable fuel drips.
