Ok here's the deal I got a computer and security box from one car in junk yard but no key.... The car does same thing as befire.... Everything works but no start... It's like you don't have clutch pushed in.. the fuel pump comes on and everything. I put old computer back in and sane thing so I looped the clutch interference switch wire. I found a car here in Dallas that has key and computer... Should I buy this or just have my car reprogram?
