The other day I was messing around in the garage and heard a faint buzzing sound. Started looking around and couldnt find it.
This afternoon I was in the garage again and I heard the buzzing sound again. Sounds like a small electric motor running. I opened the garage door to see if the neighbors were doing something that was maybe vibrating somethin in my garage. After walking around the garage and not being able to pin point anything. I look at my truck and think to my self.. "I guess ill check" so as I get underneith it its clearly the truck. Above the rear of the gas tank close to the frame crossmember there is a big black box that vibrates (haha no pun intended) now im not real firmiliar with these trucks. the lines and hoses coming off it seem to go to the fuel tank. Is the fuel pump on the outside of the tank on these?? And why is it running? It runs for about 5 minutes and quits and has not done it since. the truck was cold and hadnt been driven or even had a key put in the ignition for about 4 hours. So im going to keep an eye on this as ill be spending some time working on a wood project in the garage for a few days. Anyone else come across something like this. It runs and shuts off on its own so I dont assume theres a short or anything.. Taco is brand new maybe something crazy that ive never heard of??
