My truck has a extended crank when starting.

(2000 Jeep Cherokee)
in Winchester, VA on October 14, 2012
The truck starts when cold or sits overnight. When the engine gets hot and it sits for 20 minutes, then it has a 6-8 second crank time, before it starts. I have replaced plugs, boots, air filter. I have also replaced the crank sensor and the entire fuel pump assembly. A fuel injection cleaning was also performed by BG. Any suggestions would be greatly appreciated as it has been diagnosed by a couple Master Techs and they have no answers.

Thanks, I will check that and post my findings. I would of never thought of that. I was also thinking the ECU might be getting hot. Thanks again.
I finally solved my problem on the extended crank times. #2 injector was bleeding back and causing fuel pressure to drop, I also replaced #1 injector since it had a crack in it. 4 years later, I finally solved this mystery. Good luck to all the Jeep family out there and never give up.
