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?

 

 

Yeah Thats what Iam thinking. It sounded like it was coming from the first line. coming out of the injector pump

 

Mine has done it when it's cold for a couple years.. I'm not sure if it's good or bad but mine does it..

 

i got the same problem but i figured it was fine to

 

Well I guess I just want worry about it. Ill just put some new fuel lines on it. Then just run the HELL out of it.

 

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.
