Replaced CPS and truck starts. She sits over night and my wife drives her to work. Wife says truck was idling rough, almost stalling. She gives it gas and makes it to work. After work the truck won't start again. Any advice? I'm not a mechanic and was hoping the CPS was the issue...next guess is fuel filter....Advice?

 

What brand of CPS? Are you getting tach movement?

Did you look at the fuel filter?

 

How cold is it there, is the fuel gelling?

 

Does not say where he's from but with these record cold temps just about everywhere probably is a fuel gel problem, might try some 911/power service additive or some #1 diesel if its available in your area, don't be running any bio products in these temps, just set a bottle of wesson cooking oil outside for a while and you'll see what I mean....

Slick
