Question about 2000 Chevrolet Blazer

2002 Chevy Blazer

I talked to you this morning about my sons blazer that would not start. It ran perfect before he disconnected the negative battery terminal. This might help determine the problem, a security light came on and now it won't start. What can be done?

Where is the mass air sensor located on a 2002 chevy blazer?


The mass airflow sensor should be right by the throttle body.
Don't disconnect it without disconnecting your battery's negative cable first. You will damage it if you disconnect it with the battery connected.

Assuming you have everything reinstalled correctly and the fuel pump was your problem to start with, try disconnecting the battery for at least 15 minutes to reset the computer. This worked on my 1996 Blazer.
