This has probably been discussed before but I didn't find it.
Our 05 Revolution has a C7.
When it is cold, engine heat on or not
it takes several revolutions to get it to fire. When it fires it is not all cylinders at first.
First start when temps are warm takes quite a bit too.
There is no fuel pressure gauge on the coach.
I wonder if the HUEI? pump might be a problem.
The cold start problem has been around for I don't know how long though.
I add fuel lubricity additive when I can find it.
Will judicious use, of additive, prevent problems with the HUEI pump or do I need to plan on replacement anyway?
Anyone else having the cold start issue?
I used to have an 05 Newmar Kountry Star with the 330 CAT with the
HUEI pump.
Let say it was 40 degree F.,turn the key and wait for the WAIT light to go OFF,now crank the engine and she should run within about 3seconds. Whenever it was less then 40F,I would use the engine block
heater for 2~4 hours and the engine would start with NO WAIT light within 3 seconds.
Keep in mind that your air intake heater has to function correctly and also with the HUEI pump the oil pressure has to come up to a certain level before the injectors are fired.
When it is cold,use the engine block heater! it warms up the oil,you need less current for your starter motor and it is less drain on your
batteries.
Hope this helps.

Batteries good? Mine (C7) started cranking longer and I realized my batteries were five years old. Replaced them and it hit off much faster. Would explain the missing though. Have you had Freightliner check the codes?
