Question about 2000 Chevrolet Blazer

2 Answers

Sometimes my 2000 chevy blazer will not start. If I hit the gas tank while it is being started it will sometimes start. I am wondering if this is a fuel pump problem or a fuel filter problem. It never sputters or dies while driving it. The gas gage will not register below half a tank no matter how much gas is in the car.

Your fuel pump is going out, I would change the fuel pump as soon as possible, possibly with very little gas in the tank because the gas tank has to be removed to replace the fuel pump, and sometimes the gas tank straps will break when removed, good luck, Gary

Usually that is a bad fuel pump. Filter is not on the tank. Test it when it doesn't start, or listen, as when you first turn the key to "run", you should hear the fuel pump cycle.

Chevy Blazer no gas will not start. Changed filter, gas gage lies about level. Goes to zero when starting. Full tank.


Possible bad fuel pump. Have someone crank the engine while rapidly hitting the bottom of the fuel tank with your fist agressively. You can also use a hammer and hit the tank using the flat of the hammer head while the engine is being cranked. If it starts or tries to start, suspect a bad fuel pump

2000 blazer , every once in a while it wont start... let sit sometimes 30 minutes sometimes 2 days and it starts. Put external fuel pressure gauge on... B4, when key on... gauge shows over 60 lbs. when it...


Hi:
The fuel pumps on the Chevy blazer and their full sized trucks are prone to failing, as I had to change mine on my 1996, and yours is the same model .
Ours started off intermittently dieing, then failed all together. If you have matched up the fact that you have no fuel pressure when your blazer won't start, then the fuel pump is the most likely suspect. As you know, they are not cheap, and the fuel tank is not difficult to remove, but needs to be close to empty to make the job managable. The tank is over 3 feet long, and is better removed with 2 people if you can find help.

The plug on the fuel pumps are common for being bad and burning up the pumps. But the new pump will come with a new plug.

2001 chevy blazer not starting


I had this same problem with my 1997 Blazer, which required a fuel pump replacement as Nitrobike said. The sign to look for is when you get in the Blazer, turn your key forward to the accessory position, but not the start position. You should hear the fuel pump charging. It sounds like a hissing or whirring noise for about 2-3 seconds while it pumps fuel into the lines to prime the engine.

Fuel pump replacement isn't cheap, about $700-$1000.
