I put a whole new fuel pump and filter on my Jimmy then I had a small gas leak.I had the leak fixed. The car always started easy now I have trouble starting it>its also sluggish going up hills.

The first thing you want to do is test the fuel pressure with a gauge during the failure. This vehicle requires over 55PSI at all times and unless you are using a Delco brand pump, the rest are unreliable.
