SRT SIX sells them now....
as for the car not starting, I think you got into something that you shouldn't have...the sprint booster is a 15 minute install....lol...after you have done one.....lol....because the first time...you just simply fight that washer...but, I didn't because everyone on here warned me beforehand...so, we would need to know what you actually did while installing this little device...if you installed it correctly, you may have a faulty sprint booster, and if that was the case, then simply putting it back together should have been all you had to do. If it didn't start then, you have another problem, not a SB problem..
