My friend has a 1994 chevy blazer. For the last month it will start then die and then start back up right away. Now th blazer will start and run for 20 min. then die and will take 3 hours to start. Hes changed the spark plugs and wires, the distributer cap, the map and mav Sensor. Unsure if this is a fuel issue or what the problem is.


On a side not the 4 wheel drive doesnt work at all push button will no engage no light blinking or clicks. Sometimes it will engage into 4 low if the key is in the On posistion and the truck isnt running. Also when driving the 4 wheel drive light will randomly turn on but it is not engaged. At one time we had replaced a fuse it work for about 5 minutes then stopped working completely again. Any suggestions.


Thanks


Jared.

 

Sounds like a short, which fuse blew?

 

The fuse that went out is the TCCM fuse (Transfer case control Module).
