conected the battery wrong

ok I know I messed up and it will probrably going to cost me alot of money but my 96 camry wouldn't start so I took the battery into the house to charge it. when I reconected it (it was dark ) and I connected the pos. to the neg. and the neg to the pos. after realising my boo boo I reconected it the right way but had no power in the car . I recharged the battery and checked the fuses. there were 3 fuses burnt, one 100amp one 20 anp and one 30 amp. I changed them and tried to start the car but it would turn over no prob. but woouldn't start. I rechecked the fuses and the 30 amp one was burnt again this one is for the (multiport fuel injection system/sequential multiport fuel injection system,starting system )everytime I try to put another fuse in it blows right away. A guy told me I might have fried my alternator so he said this might be causing the short so he said to disconect all wires going to the alternator and then try to put the fuse back in. I tried this and still the fuse burnt. can anybody give me anymore advice (besides don't conect the battery that way again)on what I can try to troubleshoot before I take it to the shop and they soke me dry.

If this 30 amp fuse keeps blowing, it might have been your problem all along. You don't say what was happening when the car originally didn't start, (before reconnecting the battery the wrong way) so I am assuming this. Check all the wiring leading to the individual fuel injectors. Look for frayed insulation where the bare metal wire portion inside the insulation may be contacting bare metal somewhere on the engine or in the engine compartment. If you find any, apply electircal tape to that area, replace the fuse again and try starting the car.

Good luck.

-52 with the wind was the original problem but I will look for the wires but i'm not sure what the fuel injectors look like

The fuel injectors are attached to a rail, which is like a small length of pipe, and there is a main wiring harness that runs across the whole length of the rail. On the 5SFE engine, the fuel rail is located in between the valve cover and the intake manifold. On the 1MZ-FE engine, some parts will have to be removed to access the fuel rail, but it's still in the same general location.

well finnaly bit the bullet and brought it to someone who knows what their doing and it turns out the only thing I fried was my remote car starter. Thank god. thanks for everyone who helped.

Glad you got the problem resolved.
