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.

problem #2

Nov 102015

Sierra 2500 454 V8

  • Automatic transmission
  • 156,000 miles


Getting fuel and spark. Vehicle will crank and start sometimes but not all the time. When it starts it pops back through the intake sometimes. Runs till it gets warm and then shuts off. When it shuts off I still have all electrical power. Won't start again till cold. Almost can't jump start it immediately after it shuts off. Have replaced the battery, plugs and wires, ignition switch, distributor, fuel pump, crank sensor, engine coolant temperature sensor and crank gear (that was shredded on one side). Is not throwing any codes and service engine light does not come on. When it runs it runs good but will shut off while driving which is dangerous!
