Question about 1997 Chevrolet Blazer

1 Answer

My 97' Chevy Blazer starts but then cuts out all electrical seems to be working fine, replaced fuel filter and air filter my mechanic said the fuel system seems to be running normal and there was no need to replace the fuel pump. After the engine cuts out it fires right back up. Also before the truck dies the tachometer will fluctuate between 500 and 1500 it also happens while idling at red lights or in park. is there a sensor or relay that might be faulty or vacuum hose any info would be greatly appreciated. Thanks

On the throttle body were the air filter hose attaches to there is a TPS sensor installed on the side of it. It has three wires coming from it. One is a ground and the other two are the hi and low sides to the reostat built into it. The reostat is like a grid in a toaster you can say with an arm that touches the grid. As you push on the gas pedal this arm inside of the TPS goes to a higher position the further you push the gas pedal down. In time the grid gets worn and crusty inside that will cause a short at any given area of the grid. It will normally happen at the very low end and other spots were the arm lays at most of the time. This will cause the engine to die out although it will restart at most times. Someday it will not start for the grid will finally break causing an open to the circuit giving no signal to the computer.
This part can be purchased at most auto parts stores and any GM dealer. You will need to set the voltage to 1.5 volts when setting this at the idle position
'Godd luck to you

Have you changed the fuel filter lately? If not do so. Sounds like fuel restriction. Filter usually on frame rail passenger side. Good luck!

2002 chevy blazer fuel consumption


Usually when it comes to bad gas mileage, an air filter change, fresh oil and filter, fuel filter and making sure you have no vacuum leaks....

Also, believe it or not, improper tire pressure will affect your gas mileage.

New spark plugs and wires are a "nicety" but if there is not damage to them, then they will be fine.

My truck will not start. i have a new starter, alternator, fuel filter fuel pump, mas, air filter. any other suggestions. its fine once its started. i spay choke spray in it to get started.


I have had similar problems and had to replace the fuel pressure regulator. It's a major expense because it sets below the diaphram in the intake manifold. Ask your mechanic about it, it may be the issue. I would get about 30,000 miles between replacement, I've replace it 3 times since purchasing the 2000 chevy blazer new, first one was under warranty.
