My blazer stopped starting

Do you have a security or anti-theft light flashing?

When you try to start, do you get a click or nothing at all?

the security light does not blink. there is something clicking under or by the transfer case. I have completly taken out the fuse box under the hood...looking for a starter relay switch, I thought that might b it, if I could find it.
No, it doesn't click when u turn the key.

Check for 12V at main starter connection, then check for 12V at solenoid when key is in start (car raised on jacks). If none to solenoid, then fuse of starter relay. Another possibility is ign. switch or anti-theft. Owners manual should give instructions on anti-theft reset.
