I recently was having fuel pump issues and had a new pump installed. That seemed to solve the quitting problem but now it seem like it is really hard to start some mornings. If I turn the key to th on position for 5 seconds or so it'll fire right up. But if i just try cranking it over after its been sitting a while it'll take forever begfore it fires. It's a 2003 tj 4.0 It just seems like it is losing its prime.
