i posted awhile back about when i turned my car on it would click a couple times and then it would start...we went and had it checked and the battery and started tested out fine...the guy told us to check the wires to the battery and starter to make sure they weren corroded...they werent but we cleaned them just to be safe...well now it's clicking when i start it and instead of starting it will just turn over and over...and doesn't start but sometimes it will start and it will act like hesitating to start....has anyone had this problem and know what it could be or any idea of what it could be...please help!!

 

Sounds like it may not be getting fuel

The fuel filter on my Supra is clogged and if I spray gas into the throttle body, it start and cut off once that gas burns. It won't take any throttle input at all.

What year is your Blazer and what engine does it have in it? That may help us help you more

 

it's 93 blazer w/ a 4.3 engine

 

99/100 times when all you hear is a clicking noise and then it turns over and starts, your starter is about dead or there isn't enough juice in the battery. It is possible that the red wire from the positive battery post is corroded anywhere along its length and that is causeing the problem. Propably somplace where you cannot see it, like by the exhaust manifold. The heat from the manifold likes to burn away the cables protective coating, causeing the cable to rust out.

Replacing the red wire is cheap and easy. It bolts to the battery, and the other end bolts to the starter. Should be a wire coming from the alternator to the battery post end of the wire too. Buy a replacement cable and install it. They are less then $10.
