most common is the vacuum actuators (one under the battery and one on top of the transfer case) kind of a pain to get at both, but it's a cheap part.
more than likely its the fuel pump. common problem
The 2001 Chevy Blazer does have an ignition security system that is controlled by the computer in the vehicle. The light might come on because of an error that is coming up in the computer due to a key problem or an ignition problem. This is a common issue with the 2000 and 2001 Blazer.
trying to fix simular problem
I did a search on google and was surpised to find that the S10 Chevy Blazer has tons of problems. The most common seemd to be with the transfer case.
Yes, the doors from a 98 Chevy Blazer will fit a 2001 Chevy Blazer with a little moderation.
engine misfire. i have a '96 Chevy blazer but i don't have that problem, i was reading reviews on the car and found out that some of them do that.
Well first of all you need to specify what the problem with it is
Check for a blown fuse.
The latch on the actuator is probably broken... it's a very common problem for the Blazer. Pull off the trim on the rear door, and you'll be able to see it (and replace it) for yourself.
Several problems can cause a 1999 Blazer not to start. There could be a fuel problem or a firing problem. Check for fuel pressure and ignition spark first.
I had a Chevy blazer with the same problem. It had spark, fuel pressure, good battery & good starter. I sprayed some carburetor quick start spray & it started. They blazers have a problem with the fuel injection.
Engine coolant sensor may be bad
