My 1999 Jeep Grand Cherokee always takes a good 5-10 seconds before it starts after it has been sitting for a while; however, once it starts, I can cut it off, and restart it at no problem. I took it to the dealer, and they suspected that it might be a fuel problem however they didn't perform a diagnostic test. I purchased the fuel pump module repair kit. I installed the o ring and spacer on the fuel return fitting that connects to the pressure regulator. I've had a battery test and an alternator test. Both are good. Even after I installed the o ring, I'm still having starting problems. Did I install the o ring kit incorrectly? Could the spark plug be an issue? I'd like your feedback. I'm a novice.
