Sounds like your distrubuter cab is cracked and allowing moisture in it which won't let it crank. if it happens again blow it out with an air compressor, and try to start it again, if it starts arter blown out, then it needs to be replaced.

My Blazer cranks over and over...killed the battery : ...next morning the second time I tried cranking it over it made a poof sound and started but with a lot of chugging. Can anybody help please?


Lynda, If it is the 4.3 V6, they are prone to getting moisture in distributor which causes the symptoms you are talking about including the poof. You can have scanned to see if trouble codes are stored, you may get multiple misfire.
If continues doing this have cap and rotor replaced and if wires and plugs are old do them to. Check the attached links,instruction and guides, Good luck

2000 Blazer Cranks, Won't Start


First of all, a diagnostic wont tell them that there is arcing involved. I am thinking it is your crank sensor. It expands and retracts in different weather situations.It should make contact in all weather situations.

1997 chevy blazer s10 cranks but wont start


You have a new battery and it cranks. Turning over is cranking. You are saying it won't start after sitting for six months? What is an old mechanic? Was the cable installed at home during the one year layoff? It sounds as though you failed to hold the old mechanic responsible for installing the correct cable or adjusting the one you have ,so it will start. You have a safety switch issue by the sound of it. Make sure you have the right cable and then find out how to install and if applicable,adjust properly

I have a hard time starting my 1996 blazer the first time of the day. After that it starts easier if it doesnt sit very long


either your fuel pressure regulator is bleeding back
or your fuel pump is bleeding back.
easy fix is to cycle the key a few times that why the fuel pressure builds up and then cycle the key the whole way through to crank up your car.

2000 blazer turns over wont crank


you coul remove the # 1 plug wire (1st on drivers side) and see if your getting a spark. It may need a new distributer cap and rotor.or it just may need new spark plugs. fair warnig I am not a mechanic but have had similar problems like this that I have had to fix myself.
