I just want to admit that i am a super newbie. I'm not a gear head just a starving artist who lucked out with a great truck. My truck is a 1991 pickup 22re and has run well since i've gotten it.

I recently drained my bettery by leaving the headlights on while it sat fore two days. there was absolutely no response when I tried to start it. I asked a neighbor to help me jump start it and after I hooked up the cables on his battery he grabbed the other end without asking and crossed the cables. i didn't realize it until i got in the truck and turned the ignition once and saw smoke rising from the positive battery terminal. by the time I switched the cables to to the proper position it was to late. i tried starting the car but didn't get any response. I pulled the battery out to charge it over night. The next day i checked all the fuses and found the ALT fuse burned out. After I replaced it the will crank but will never turn on its own. ive looked at all the fuses and they all seem to work fine. I even looked at the ECM to see if it had burned out but it looked and smelled fine. at this point i don't know what direction to take with it. please help. Where should I start?

 

Test the alternator, I'm guessing it's cooked.

 

swap battery and see what happens then!!

 

I have a 1988 Chevy Blazer. I got a new battery, fuses are good, starter is good. But it won't start up. Any ideas of what could be the problem?

 

It's a CHEVY?????
