Venting the hood also helps w/this issue. From my experience w/my '01 the vapor lock issue occurred on my XJ after slow speed driving, sitting idling or after I'd driven a bit around town and stopped for a few minutes (to get gas, coffee, drink, etc...) and then trying to start back up shortly thereafter.

After adding hood vents and new Fuel Injectors I've had no issues w/this. I also have no head shielding installed on my '01.

 

Mine heat soaked until I got rid of the heat shield and wired my electric fan to a switch so I can run it all the time.
No problems now.

 

I have hood vents, wrapped my injectors with heat shield, oh and now have the new heat shield. So far good. This week should be a good test. Going to be around 92 and no rain in sight until like Sunday.

bump anyone know the part number for this?

 

The heat shield? CBXCB060. My Jeep Dealership had it in stock when I bought one about 3 years ago. Cost me $2.20 not including tax.
