Good evening fellow Volvoers. I own a 2004 V40. Ive had a wee bit of trouble on startup recently. Not only does it take 2-3 times longer to start, but the rpms take a considerable dip after releasing the starter. Ive replaced the starter motor today and it hasnt made a difference. Any recommendation or insight into the problem? Might it be the fuel pump?

thanks in advance.
