CHEAP FIX!!! I had the same problem 2 years ago with my 2000 Blazer. I went through hell trying to figure out the problem with many mechanics. If the security light is blinking you have to wait 10-15 minutes for the system to recycle. When the light stops blinking it will start. Here's the issue...the GM security feature is defective and there is no way to turn it off. Don't bother wasting your money on a new ignition because it does nothing (I know because I replaced mine). I got a hunch that if I put in a remote starter I could then bypass GM's security feature and it would be fine. IT WORKED! I put in the remote starter and have not had any issues with starting for over 2 years now. ON THE OTHER HAND!!!!! my 4X4 is faulty. The 4X4 lights on the dash blink or go out and the truck runs like crap. It will be fine for a little while but then the light starts going on and off and the truck runs crappy again. This problem I can't figure out...any ideas?

I reget ever buying this stupid thing!!! Mine will run bad when I stop at alot of places shopping when it is hot out side. When I come up the mountain it feels like it is vapor locking. If I have to stop it dies. With the security problem it scares me that Im going to be stuck in the middle of the road and it wont start for 10 freakin minutes. I bought this car for my daughter to drive. We have about 3 months to get it fixed or she'll end up driving my truck, cant have THAT!! So we will try the remote start and go from there!!!
THANKS!!!
If you have any ideas on the vapor loack thing let me know!!!

Okay, this is a fuel injected vehicle and cannot vapor lock. Not saying there isn't a problem, just that it cannot be vapor lock.
 
Several things can cause the problem you are having, including the MAp sensor, crankshaft position sensor, any number of things. The system will only set a code if the problem is a hard failure, or repeats itself. Regarding temperature, if the temps are higher outside, the temps are higher around all those sensors used in the engine control system. Also of note is that the engine and engine compartment gets even hotter when you turn it off. There is no air or coolant flowing, and that chunk of iron just gets hotter before it starts cooling back down. Has a GM dealer checked the vehicle? Not all independents are qualified for the sophistication of an OBDII system and will just keep swapping parts until they stumble across the problem.
 
Put a little logic into the problem and observe closely for any other events at the time of failure, or symptoms that may seem unrelated. Just remember that the 4.3L engine and control system is in 100's of thousand of vehicles on the road and has a very good history.

Ok here is what happens to mine and please tellme if yours did the same thing. If it sits overnight and I go out to start it, it turns over but doesnt start. If i wait about 10 minute sometimes more and turn it over sometimes it will start sometimes not. It took me over an hour to get it started last week, but once it is started it will turn over everytime after that with no problems. I just want to be sure that you had the same issues before i install a remote start. Because if my problem is different it would be a waste of money. Thank you

Mine was not doing this before BUT now it is.... I dont know what to do at this point.. At time it wont start and the security light isnt blinking. It still does the security thing BUT now it does this also.... OOOHHH and jlflemmons thanks for the info but as I said in my original " It feels like it is vapor locking" I know that it is feul injected and cant vapor lock. I have put a little logic in to the problem and I still feel is it a piece of #!$.....

So, by remoe starter do you mean a new key fob? I asked at the dealer, I can get one for $70. My alarm sysytem gets set and then won't let me in - even with a key. I've found if I wait, then reset it form inside the car with the key in the ignition after a while it does shut off and let me drive. Otherwise, even with the key, I'm s.o.l.
The thing is, I'd rather disable the whoel thing. Anyone know how? Is it hard? If I have someoen do it, how much should it run? I'm a former toyota girl and am CLUELESS as to what to do with this!

I have been told you cant disable it. You have to fix it. I dont have the keyless entry thing on my keychain..... The remote start is a way to start the car from inside the house or from outside the car.

Ive have my 01 Blazer ls for about 6 years now. the only major problem ive had happened about 2 years ago. Had to replace the fuel pump(that was fun dyin on the highway in traffic!) and I had to replace the cat converter(made the car run like total crap and actually died on me going up a mountain) which i think might be one of the problems being discussed on here by some. I am also having the "I dont want to start for you today" fight with my truck as of late, I dont have a keyless entry system on my truck so i dont know wtf is wrong with it now. I've put a new fuel filter new plugs, i'm fanatical about oil/filter changes, i've even put a new hot wire to the starter(old one wore out-damn those dirt country roads!) So I hope my fight with my truck might offer some insight into some of the problems you guys are having.

I had another blazer before this one and it was doing the cough cough thing when it would get up to normal tempature. I called my grandpa, a chevy man from the begining of chevy, and he told me to change the ignition module. He said there is a jell stuff between it and the distrubutor and if that brakes down then it wont work right. I went to get one, Im a woman, and was told OH NO it cant be that its this...... Over and over and nothing they were selling me fixed the problem. Finally after about $500 I bought the $40 part. My husband put it on and BAM the problem was gone. Should have listen to grandpa from the start!!!!! GOOD LUCK!!
