Another hard cold start...

[Javespy10]

Im haveing an issue with my truck it has troubles starting when cooled down. I actually have to pump the pedal to get it to start, but after it is warm it starts right up. If i dont press the pedal it wont start. Any suggestions? or opinions
thanks

i just checked it and it is showing no DTCs... Could it possibly be a sensor for the injectors?

Check your FICM.

Ficm voltage is good on the insight. How else can i check that?

[nylyon]

There's a cover on the FICM. Remove the cover (moving the degas bottle out of the way) and test the drivers side bottom most terminal on the 4-screw model or the top most passenger side terminal in the group of 4 on the 7-screw. Be CAREFUL not to ground the screw / terminal to the side of the case. Check with the engine cold, key-on engine off, then when cranking and then finally when running. 48V plus or minus a volt on all tests are good.

My truck is doing the exact same thing as we speak, I have mine in the shop and they haven't figured it out yet. Let me know if you figure your issue out

hey guys sorry it has been a while since school started back up i have been crazy with work then school all night. I just checked the ficm voltage while cranking and it stayed above 48 volts. From what i have read that is good. Recently the truck has been acting up... longer to start, puff of white smoke when it starts, and stalls. The stalling thing is most annoying, it usually happens when I give it throttle then let off and stalls. Also when i put it in reverse and give it throttle and let off. I dont know where to go next. Any input or past experiences?

Im having the same exact issue right now, except mine is black smoke. Bluedemon6.0 told me to check my alternator and my batteries. I will let you guys know if find the problem! Ordered my cts today, will be here next week sometime

Is your egr deleted? If not I would disconnect your egr valve and see if I remains.
What is your voltage? You have to have 12v in order to provide proper voltage to the Ficm.
If you don't know the health of your batteries that is a good start. I would go to the parts store and have your batteries load tested, have them check the alternator while they are there. It doesn't cost you anything but about 10 min. Of your time.
You also need to check your codes. If it is your egr it might not throw a code but your truck will run like chit. Keep us posted
