supra 1991 wont start
 

hi i am new in this forum and i need your help my car wont start i recharge the battery and replace it but i made i mistake i place the battery on the wrong side and i connect the fire cable on the ground side of the battery and i touch the ground wire in the fire side + of the battery and sparkles came out just for 2 seconds so i change it to the right side so now i have some lights when i open the door the headlights work okay. but no radio no electrical power i try to start the car and nothing not even a sound i checked some fuses and are okay did i messed up an electrical component like the computer or a big electrical part of the car burned ,,,,,thank you for your time please let me know

well if your really bad luck, your fuses and relays didnt do there job and just melted like mine tend to do.

other wise i say take a look at the relay box under the hood by the diagnostics box. bet you blew the acc relay.

you know what my friends car was doing that yesterday take into mind though her car was a 4runner..but her negative wire had no ground wire do you have a ground wire and the only way i started her car was to jump start it..make sure there is a ground wire and enough juice

I'm thinking that if you are getting this freaked out over dicking up your battery.

You may not be ready for the challenge that is supra.

I hope you have an ample tool collection.
