You might have a voltage regulator problem. If the vehicles voltage drops by more than a volt or two when everything electrical is turned on, that's the most likely problem.

It could also be a bad connection somewhere after the alternator. Or, you have a failin alternator.

Either a weak battery or a defective starter. Have you checked your battery voltage when it will not crank? Cleaned your battery terminals?

Cranks runs good but wont crank after running a while then cools down and cranks it does not turn over on speed till it sets a while what could cause this

It sound like you have a bad starter. When it is hot, it is drawing more amps than the battery can supply. You may also need to test the positive cable to the starter from the battery. To do this, you need a multimeter. Check the voltage between the positive and negative cable at the battery and note your readings. Then measure the voltage at the starter between where the cable connects and the case of the starter. Compare the two reading. If you have more than .5 volts difference, then the positive cable has too much resistance and needs replacing. Check for corrosion and make sure the cable is tight as well. I am betting on a starter though.
Good luck. Hope this helps!

Ive replaced the battery and starter but it still wont turn over' has power and it starts to click but nothing. 1996 chevy blazer

Check that the battery has at least 13.6 volts and if it does the the starter solenoid may be bad as this occurs frequently these days with rebuilt starters. You may need to return the starter for a replacement but before doing that make sure both your battery cables are clean and tight at both ends.

My 96 chevy Blazer wont start but the battery is fully charged wont click or turn over

Your pendix on your starter might be stuck, lay down under blazer and tap on the starter with the handle of a srew driver or a small hamme to see if it frees the pendix. You may have a faulty starter. You can jump the starter with a screw driver to see if it works, but if your not familar with that I don't suggest you try that.

There are no free full diagrams on the net, you need to charge and test the battery, clean the battery cables and run a voltage drop test as well, replace them if the are badly corroded. Kragen will test the battery for free.
