Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

About a year ago my truck started to have problems starting on the initial turn of the key. I would have and still do have to turn the key on, off , and on again in order to prime the fuel system. I was told by the dealership that it's probably the fuel pump loosing its prime causing the fuel to drain back into the tank. This is just an inconvenience and hasn't caused any mechanical problems that I know of. It is certainly not worth paying a thousand bucks to drop the fuel tank and replace the fuel pump. I will just have to live with it.
