Today When I cranked my truck. The temp was around 34. I heard alittle knock. I pop the hood it sounded like it was coming from the injector pump. after it warmed up I didnt hear it anymore. I sure hope its not going out. has anyone had this problem before?
The same thing happen to me when it first got cold ( 20 degrees) scared the heck out of me. Popped the hood and got looking.. It ended up being a spot in the belt popping real loud @ fan pully.. (Argh). I just thought it was fuel knock.
