I'd go to AutoZone and have them check for trouble codes with a scan tool first. Have a pen and paper ready, since there could be several codes set. I'd be interested in any codes that started with the letter B.
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.
YOU WILL DIE! have you check your IAC ??
There is a magnetic switch in the steering lock/ key switch. If it is weak it will do that. If it dose leave the key on for 10 min. The light will quit blinking, turn key off and start motor. This is a dealer fix. Parts are up ward of $700. I just wait the 10 and go on my way
most likely a fuel delivery problem. i use carb cleaner to spray a little down the throttle body (where the carb used to ve) and see if it starts. if so then you probably need a fuel pump.
I would not worry to much about this noise when the motor is cold; engines have clearanaces that come together at operating temperature. If this noise happens when the motor is at operating temperature then you might have a problem.
Possibly a security system activation light.
When ever the service engine light is blinking you risk doing serious damage to the catalytic converter. I would recommend not using the vehicle until the problem is fixed. Replacing the cat can be very expensive. Have a trusted mechanic diagnose and correct the engine problem.
If the air conditioning light is blinking on a 1992 Chevy Pickup, it is possible that the Freon is low in the air conditioning system. it is also possible for this light to blink when the radiator fluid is low or there is a problem with the air conditioning belt running the pump.

The security light on a 2001 Chevy Astro Van can be reset by disconnecting the battery for 30 seconds. This resets the system and turns out the light until another problem is detected.
The most common reason for this condition is a faulty ignition switch. It loses contact momentarily while cranking, causing a voltage loss to the security system and starts the 10 minute security timer in the computer. It will not start until the timer runs out. Usually the key has to be left on after a start attempt for the ten minutes. Some cars require 30 minutes.
if your dash lights are fading in and out you probably need to go to auto zone and have your alternator test and a load test done on your battery
The fault key start is a problem with Chevy caprice's and it starts with the key itself which has a RFID chip and that runs about $35.00 and if that does not work then you have a problem with the transceiver in the steering column and that has to be fix by a professional and it is costly
what does it mean if my brake light is blinking on and off when its pushed down in my 1999 Chevy silverado

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.
