I just welded a new floor patch and didnt disconnect the battery. now my car wont start and its not getting any fuel or spark. just put in new plugs, cap, and rotor a week ago and i can hear fuel pump when first turning on key. what can i do. did i fry my comp.

 

Did you check fuel pressure? Unfortunately, it sounds like you may have damaged something electrical like the computer. I don't know exactly how to go about checking a computer to see if it has been damaged. I guess I would just start eliminating the alternatives. Try doing the paperclip trick and see if you can get the SES light to flash code 12 - ECU functional code.

 

ok so i just did paper clip trick. it was 1 then pause then 2 then pause and kept doing this
