I have a 2001 gs300 the battery went dead so i got another battery but i hooked it up wrong and the alarm system started to off. i hooked the battery up right but now I'm not getting anything. i finally replaced a couple fuses and the car will crank but it won't start i don't hear the fuel pump turn on i checked fuses and nothing. also my dash won't light up at all what should i do

 

Find the other blown fuses. I'm surprised it didn't blow the main fuse when hooking up the batter backward. I have a 2IS, but there are several fuse box locations. You need to locate the fuel pump fuse and see what else is blown there. Also, with no clusters lighting, I'd locate the fuses related to that.

I think there must be one in the engine bay as well. Got a manual?

 

yes i have a manual but my dash board and radio won't turn on

 

That symptom sounds very familiar. I think this happened to a guy over in the 2IS forum.

Hoping it’s not the alternator, but all in all I can’t think of anything else it could be. Praying to god it’s not the ecu or a burned wire somewhere.The ETCS fuses mentioned in the second and third link I checked still look good. Has to be one of these issues though but I feel a little better about my situation now. Few threads I found are all generally saying the same things. Thanks for all you guys’ help!!
