Having problems with your 2000 Pontiac Grand Prix ?

My 2000 pontiac grand prix 3.8l keeps blowing the fuel injector fuse pretty much everytime the key is turned on

Answers :

Disconnect all six injectors, turn the key on--does the fuse blow? If ok, start connecting each injector in turn and check the fuse each time. Turn the key off while making each connection. Hopefully, you will find one injector that causes the fuse to blow. If the computer output for that injector is on all the time, the injector coil will burn out. A scanner reading of the computer should show a problem like that and should show which injector is a problem. The computer operates each injector directly, so a stuck output means replace the computer.
Might want to chk. for a bear wire on the injector harness that might be grounding out, or might be pintched, if its had engine work done on it in the past. Also chk.wear the injector harness plugs into the maine harness too.
