My 16 year old daughters 1995 Blazer is acting up. 133,000 miles on the odometer. Died on me the other day. Would turn over, not start. Replaced Cap and Rotor. Starts and runs. Blazer is running and seems to stumble when driving at any rpm's. I checked the fuel pressure. It was good. Changing plugs and wires in the morning. Now the wierd part. When the temperature outside is above 90 F. It won't even turn over. Not even a clicking sound from the solenoid. Any help is appreciated! Oh yeah! No codes show up on the scanner.
