heres the problem. i didnt realize it til it was too late, i had my battery cables switched around. i put a new car battery and i thought i had everything right, then i looked at the negative and postive, it was wrong. i didnt realize, stupid of me. i corrected it, now it doesnt have power at all. no lights, no radio, no nothing.

luckily i didnt try to start the car with the cables wrong like that.

so what do i do now to start my car up? this is very urgent, i need my car to go to work. thanks

You most likely popped a fuse or worse fried the ecu.

Fried the ECU?...uummm...No..... He reversed polarity,The 80A battery fuse is blown. Its under the hood in the fuse box. Autozone or advanced has em for about $3 a pop. replace it

No, If you do that it reverses the polarity. there are ways to discharge a battery but there is no reason for you to. Once the battery is disconnected you use a multi meter or equivalent to check how many volts the battery has. it should be 12.46V with NO LOAD. And with a load it should not drop below 10.00V also with the car running and the Alternator working properly it should read anywhere from 13.5V-14.5v
