I have a 93 S-10 Blazer. It has the 4.3L. It had been starting and running fine till last Friday. I wentto start it in the morning, and nothing. It did not click or anything. The battery is fine, i pulled it and had it tested. I thought it may be the P/N switch. changed it. Next guess was ignition switch. changed it. Next was the starter. (that was a pain to pull). It bench tested fine. I am running out of thing to try. It has almost a full tank of gas, and I do hear the pump kick on. I do not see any bad fuses. I am open to any help. Thanks in advance.

 

My truck is still not running. I had not worked on it in several days. I decided to warranty out the ignition switch. Thought I may had a bad one. Something strange happened. I pulled the two plugs, and as soon as I plugged in the new one, the radio came on. The key was not on, or even in. So there is power to it from somewhere. I was not ever grounded. The blazer still does no start. I did ground it, but but it is not mounted. Any ideas?

 

check to see if you have spark and go from there.

 

check for burnt inline fuse to starter.

 

Wait. Still doesn't even "try" to turn over?

 

Do this by removing the positive battery cable to the starter and pulling on it. If it stretches quite readily, the fusible link is toast.
