Battery Reversal

[Tokyo_Terror]

ok so i pretty much made the most rediculous mistake ever the other night... i bought a new battery and brought it home to put into my car and for some reason the terminals on the battery were reverse from what my other battery and i didnt notice until after i had already put the battery in and hooked it up... i found a relay that was blown and i replaced it and i thought that that was the only thing that happened until i went to start my car. it turns over like it should and all the lights work fine and everything seems fine but it seems like it isnt getting any spark... and i know that its getting gas because i can hear the fuel pump running and you can smell the gas after a few minutes of trying almost like i flodded it. soo what could it possibly be, i have no clue what could have gotten f-ed up from hooking a battery up backwards can any one give there oppinion? it would be greatly appreciated thanks

Quite a few things can go bad when you reverse the battery. You may have fried the ECU.
