Starting Problems

[wayne4252004]

Need some good advice on the starting problem I'm having with my truck. When I turn the key, I can pretty much count about three seconds before the starter kicks in and starts the truck. When the starter does engage it is very sluggish. So far I've replaced the battery and I've had the starter checked at the local parts store. What else can I do to troubleshoot the starter? All the parts store guy did was plug it into a machine and turned it over three times.
