I own a 97 GSX with 80,000 miles on it. Bought it new and have done all the required maintence. When I start up my car in the morning, I hear a scratching sound that lasts about 1-2 seconds. It happens after I let go of the key when starting the engine. I had a friend check under the hood when it was making this noise and this is what we found out. It is coming near the intake manifold on the engine . I think it is the starters brushes are not disengaging all the way and that is where you hear the straching sound come from.

. Last but not least as with your car mine only does it if it has sat for long periods of time say 4 + hours or more. It never does it again after it has been warmed up. It's crazy! Just curious... how many miles are on your car? My car has 76,000 on it currently.
