97 S-10 BLAZER Anyone know why this thing will turn over a while then all of a sudden the dash and headlights come on and the engine starts? Sometimes the lights won`t come on and it will not start. If I put the charger on it , same thing untill I turn up the amps on the charger then all the lights come on and it starts right away. Tryed new battery and same results. New fuel filter, fuel pump is running. WTF ?

If your battery is an original AC Delco, I would bet that you have corrosion behind the positive post inside the battery. This is a common problem with the AC Delco batteries. I had the exact same problem with my old Bravada. Start one minute, not the next.
