94 GMC K1500 Knocking

[sexybanana4141]

When I turn the key to start the engine, I hear a momentarily knocking coming from the passenger side floor. The truck runs fine.

not enough information to take a guess at.... knocking while the engine is running....kocking sound before the engine starts...

It would be easier to give more information. Could be many things, loosen nuts and bolts, auto part damage, electrical problems.
