2002 Chevy Blazer stalls

My 2002 Chevy Blazer starts, then RPMs drop and it stalls. I take the key out, then insert it again, start it again and it runs fine. It does this intermittently - 3 times this week. Today, it did it, but it wouldn't stay running after I took the key out. The only way I could get it to stay running was to keep my foot on the accelerator. After driving for about 10 miles home, and puttin git in park, it stayed running. There is no check engine light, and when I had it at the mechanic earlier this week, there was no code.

    I have the same problem. I am currently thinking that the cause is one of the following two. My first guess is that, for some reason the idle is set too low. I don't know how it would have changed, but mine seems to be related to the cold weather change. When I warm the car up (driving for 10+ minutes) the problem usually disappears. Or, secondly, I was thinking there was a short in the steering column because everytime I would turn the steering wheel, the car's dash lights would flash, the RPM, MPH, and all other dials would flick back and forth like they were widshield wipers. Then if I let the car idle it will die. This leads me to believe that there is a short in the dash draining the power from the spark plugs when I let the car idle. Additionally, if I turn the car off in this state it will TOTALLY lose power as in the power locks don't work and I can't even get the key out. If this happens and I let the car warm up in the garage when off, later I can remove the key.

    Did this fix your problem , I have same problem. My car was stuttering a bit then did ok for a few miles. As I pulled in gas station it died. I have yet to get it started now, I replaced fuel filter hoping it may be problem but no such luck. The engine turns over but just wont start now. Maybe not get the spark needed?

    2002 Blazer intermittantly will stall right after starting. I have to hold the accelerator for about 10 minutes until it idles normally (500 - 600 rpm) to go. Most times it starts and runs just fine. I never can tell when or where this stall problem will occur. It could be the first start of the day or it could happen after the 2nd, 3rd or 4th stop/start - I don't know when it will happen. All diagnostic codes of the computer come back normal and it doesn't happen while the service man has it.

Check airflo sensor or potentometer,throttle pos sensor; if revs are to low when turning the wheel the power steering pump will draw power from engine, causing your other problems

Vortec 4wd 2dr auto trans stalls while drive

you might want to look at your O2 sensors, they can cause the motor to run lean or rich. also you might have an electrical issue that is tripping your ECM. your electronic control module might be faulty. best solution is to get a trouble code reader and find out what your on board computer has stored. from there you can repair and clear the codes.

2002 chevy blazer won't start

There is a module in the ignition cap that is known to go bad. If it is this part, your truck will almost turn over, but not quite. I would check there first. Once you get it out, one of you local parts stores can test it.
