So the last time I qrote my 90 Blazer wouldnt start, I had good reason to believe the battery was dead due to my own neglegeance. Now I had been driving yesterday all day and it started fine the whole time until last night I got the kids in the car went to crank it over and it made a very quick sound like it was going to start and then nothing. I checked all my connections disconnected then connected again and nothing still. It acts as if the battery is dead but I hooked it up to a charger/tester and it read full. I tried jump starting it this morning and nothing. It made one really quick sound like it was going to do something earlier and now nothing again. WTF is going on? Can anyone think of anything. Ignition/plugs/short or something maybe I dont know. Its almost 100 degrees out but this thing should still start! Please help I have to be at work in the morning and my back up car just got hit in the driveway the other day pushed throught he front of my house and totaled so I dont have a back up now.
