Usually a sign of a faulty idle air control valve, vac leak, or dirty throttle body.

you may want to check fuel pressure possibly fuel pump try banging on the gas tank with a mallet while someone tries to start the car if it is a fuel pump you may be able to get it started but pump will still need to be replaced

SOURCE: My 1992 Chevy Blazer S 10 is revving really high when it starts

i have an s10 that would rev up high. i hooked up my scanner and it didn't give me much information, so i started researching. it took a while. i got my manual out and looked up all of the sensors in the fuel system. i even paid some web site $10 for help {wasred my $10} and they were no help. so i researched all of the sensors and found out their symptoms when they malfunctioned. the culprit turned out to be my water temp sensor. here is how it works, when you first start your engine the water is cold, the sensor sends out the information to the brain [warm me up] so your engine idles high to help reach operating temp quicker. when the sensor malfunctions it will send the wrong info to the brain [i'm cold] so the brain revs up the engine in an effort to get warm .i replaced the water temp sensor and the engine is back to normal.

No, the fuel pressure valve may be stuck open so that the fuel pressure is too low when you start up, but the pump keeps up after the engine starts...
The fuel pressure valve is draining the fuel back into the fuel tank when the Blazer is parked.

SOURCE: where is my fuel pump relay on a 1996 chevy

Its in the fuse panel under the hood the cover will tell you where it's located.You also may need to replace the crankshaft speed senser,if it's gone the relay won't work.If you listen and hear no fuel pump running when the key is first turn on then it may be a relay issue or the wireing to the fuel pump.

While driving my 1996 chevy blazer stalls out,repeatedly, what would cause this to happen


If this only happens when you let off the gas pedal when slowing down clean the throttle plate in thew throttle body. That should at least help with the problem if not solve it.

My 1996 chevy blazer has a hard time shifting out of first. It's a the 4x4, it has to reaaly rev about to finally slip into 2nd. It is an automatic. Waht could be causing that?


I don't know about a 1996 modle, but older chevys had a vacume modulator right side of transmission ,above pan some where between frount corner, and middle of transmission.
if the vacume line came of motor would rev extreamly high before a shift,(if it ever did)
my 1988 GMC with 700R4 trans does't use the modulator valve. yours may not either, but it's worth a look.
I hope this is helpfull
