2000 Chevrolet Blazer: won't start

Filed Jun 13, 2014 · Fuel system · 98,000 miles · CA

Gas gage bounces around and fuel light comes on even when I know the car has a full tank. I have to track mileage every time I put gas in the car. I also have a problem with fuel pump not getting power and r I have replaced the fuel pump 3 times and it will have the same problem days to wks after replacing the fuel pump. I have searched on google and their are many people having this same issue. I have taken it to 3 different shops and no one can figure it out I am very frustrated. Their is code that shows up when tested. The car has broke down many times with my daughter in it. I never know if I turn the car off if it will start back up. At times in the morning it wont start at all and my daughter is late to school due to the car not starting and having to find her a ride. For the past 4 days the car will not start at all. Their is no power getting to the fuel pump. I am so frustrated!!

Go to vehicle, try to start, "security" lamp begins to flash. No start issue. Have to wait for 10 minutes and try again, about 50% of the time is starts, other 50% you have to wait another 10 minutes and try again.... Gm passlock system issue. Is it the ignition, the bcm, the ECM....?

See the federal safety agency item# 623034. Security lamp illuminates while driving and then the associated "passlock" security system either stalls out my engine while driving or causes a shut-down of my vehicle whereby the engine will not start for at least 10 minutes. This has happened late at night, at intersections, gas stations, etc. The amount of times I have had to wait for this security system to "reset" has become frustrating. I have done extensive research on this via respectable online forums, and there are many owners not just of the 2000 chevrolet blazer but of a number of vehicles in the entire gm family who have this same problem. We are all crying out for a recognition of this being a safety issue, not just an issue of inconvenience. Failure to start and stalling are symptoms that are only going to lead in one direction. There are literally hundreds of posts on this issue if one goes to an online forum and searches under the terms "security light" or "passlock" within the gm context. I have been to my dealer numerous times, have attempted to work with chevrolet, and nothing seems to be getting resolved. I am under the impression that a mechanical solution to this problem does not exist, short of disabling the system altogether (which dealers are not allowed to do). I would welcome any further contact from the federal safety agency regarding this matter and would gladly go to the expense of photocopying and sending the binder of materials I have collected on this subject. If it will make a difference in preventing a future injury or death (if any have not already occurred), I am all for it. Thank you for your time and efforts on behalf of auto safety.

The fuel pump,line and tank are faulty at 35000 miles. I bought it as a used car from santa ana hyundai who agreed to fix the fuel pump but did not. The transmission is not changing gears properly, it would not start when I turned it off to get gas on 9-26-03, the left front end is popping with a loud noise,the brakes are not antilock brakes,it feels as if I am hitting metal when I stop hard,the panel lights would flicker, lights on dash board when flash when I had seatbelt on. I had a chevrolet dealership fix the minor things. The battery cable was loose and they oiled the joints to stop the squeak. The dealer refused to fix the fuel pump which is unsafe and demand I pay him money that is already above the price of this car. I am paying $14,000 plus for a 2000 chevrolet blazer with a faulty fuel pump.the door entry will not properly take in the key to open the door.the gauge meters were dancing back and forth and not properly reading the fuel.it was a rental car before I bought it so I had no real history of recalls or mechanical reports.

While driving vehicle stalls out. Consumer states that there are power surges. Upon sitting at a traffic light vehicle stalls, and will not proceed to go. Also when vehicle has sat overnight it will not start the next morning.
