locating starter and alternater on a 98 s-10 blazer

well if your battery is good then the alternator is probably good yet so that leaves one thing the starter which is a very common item to start failing ,since it slowly goes weak over a long period of time you wont even notice it til it doesn't crank the engine very fast anymore or it fails completely . It is located on either the right side or the left side of the engine and is easily accessible from underneath to remove it but before you do make sure you disconnect the ground wire from the battery and put it away from the battery so you don't get a shocking surprise as you remove your starter and pay close attention to how the wire are taken off the starter and two things you can do here is either make a drawing of the layout or if you have a decent digital camera take a picture of the connections and take a picture of each wire you take off that way in case you forget you revert back to the photos as a reference . Now if this seems a lil too much for you to handle then take it to a good garage and have them take care of it ,this is a very common item to replace so they should be able to get it out and back in under an hour easily . good luck

For sure that's good advice. The poster doesns't give any information that would help such as whether it turns over at all, clicks, or turns slowly. Just based on age though, if it has near 100K miles, the starter could well be dead from either the solenoid or worn brushes. If he could find the starter and tap on it with a hammer or chunck of wood and it started, that would pretty well convict the starter. If it has that high mileage, I'd change it on general principles anyway. And how does this poster know the battery is good? He checked it. Does that mean that the top is clean? Did he measure the voltage under load. Don't you get tired of listening to calls for help when people won't help themselves?

No wonder it won't start, someone stole the alt and starter! :)
