Emergency! Cold Start
 

Need some help. Forgot to plug in my 2007 Cummins 6.7 last night. It's about 20F this morning. I tried to start it this morning and it fired immediately. It ran for approximately 3 seconds and died. It did this 3 times. Now it won't start. It's plugged in now warming up. Any ideas???

How cold was it overnight? Might be jelled up fuel.

Pulled and reprimed the fuel filter. No gelled fuel. I think it's either the fuel pump or the injector pump. Any ideas?

Sounds like you have some issues. I fired mine up -25. Not plugged in at all. It didn't like it and died a cpl times. But warmed up and ran fine. Good luck
