Re: Glow plug lite/cold start

Huw," cold start valve" is Boschspeak for "cold start injector", and , as I
stated, it only gets 12v+ when cranking, and grounds through the thermotime
switch. True, the pump cycles briefly when the key is turned on (KOEO) and a
1 to 2 sec wait couldn't hurt. Hey, we could name this the Huw Powell pause,
and you could achieve your 15 minutes of fame in a few short years. And, I
might add, you could read that Stephen King novel I mentioned, a second and
a half at a time, for decades. Enjoy your weekend. John
