bad computer?
hey guys whats up been a while since i've been on! got a new quad that needs some work but i'm having a hard time figuring out whats wrong.... so the guy said it over heated because of a leak in the radiator he says he fixed it...?... and it still didnt run right but when i got it it had no spark and the fuel pump didnt run so i shorted out the neg. side of the fuel pump to ground before i knew that could damage the computer but when i shorted it out the fuel pump actually ran a few seconds after i shorted it out does that sound like the computer would be bad?? or did i just blow it for sure?? any suggestions or input would be greatly appreciated!!! not sure where i sould go from here to fix it!

You may be okay since the ECU wasnt supplying ground in the first place.First thing I would do is hook up D&M and see if ECU will take a map and HEX.If it does then you need to start checking grounds and wiring.If ECU wont take a Map and HEX then you will need a new ECU its not a bad idea to send your ECU out to have this procedure done just so you KNOW it is good since even the wiring going to ECU from D&M could be at fault.I usually will do this just for cost of shipping.Send it over and I will check it out.
