96 Blazer won’t start!! EDIT

I have a 96 S-10 Blazer... recently I had some trouble getting her to start in the mornings (when it?s cold or wet?). Acts like it wants to....tries to turn over but won?t catch. By the time I come home starts just fine. Everytime I had someone look at it nothing was happening. Never did anything except hope it would start. A few weeks ago it started happening again & I had a friend look at it. He replaced a temp sensor? Said it was bad & that it was telling the computer the truck was overheating therefore not allowing it to start? Seemed to work (or at least help) but.... Now, for the past 3 days my truck won?t start! The battery is almost dead from trying. I?ve heard everything from the starter to the fuel pump!! I don?t know what to do...I cannot afford to take it to a shop or dealer! Please help!

Do the basic diagnostics:

  1. Fuel/Fuel Supply
2.Spark 3.Air 4.Compression

If you are getting Fuel at the right PSI, and the injectors are pulsing. Move to Spark. If your getting spark, pull one or two spark plugs. Look for signs of fuel fouling. If you have good hot spark, and no fouling, move on to air & compression.

Buying a factory service manuial, or barrowing one from a library will help you trace the problems. Charles

Actually that is not an S-10 that you have. The S-10 chassis was phased out in '94. Since it's a GM you should be happy it made it this far. Beyond the warranty is pushing it for a GM.

Remove the distributor cap and rotor and look for a metal plate in the bottom. It's got a sensor attached to it, and some wires going to it. See if the plate is loose. If it is, tighten it down and see if that helps. I knew of a '92 GMC small pickup (can't remember what it's called) that would sometimes start, sometimes not, sometimes die while going down the road. I helped the owner locate this plate and it never had a problem after that.
