If the vehicle is hard to start after setting overnight, the problem could be the fuel pressure regulator has failed and is allowing the fuel pressure to bleed off. A failed fuel pressure regulator will should be replaced.

A/C condenser located at the BOTTOM of radiator 2 feet off the ground. Gee, wonder why it picked up a road stone and went thru condenser? Now my 11 month old Versa has to have $1000.00 of repair to fix an obvious manufacturers design flaw. Not happy.
