Jimm 2/3/2013Need more information - what type of sound is heard? Is this a whine, clunk, scrape, grinding, squeal? Have you raised the hood to observe for yourself - with a helper starting the engine?
Like to offer further assistance, but without more detail - it's pretty difficult to diagnose an engine loud noise problem via the internet. Post a reply using the 'Diagnose' feature on the AutoMD website for further assistance.
