Since the rebuild on my 3.0 v6 I have had a small issue that I have been trying to solve but to no avail it still exists. Since the rebuild more than 4k miles ago I have had problems with the engine starting right up. First thing in the morning and right after it has been running for a while it will start right up no problems, and very well at that first turn of the key. But after driving it for say 15-20 min then letting it sit for an equal amount of time, it has a hard problem starting. I turn the key once let it turn over, nothing, do it again nothing, third time kicks right over little flooded smell but nothing big. This has been happening since day one. I have checked the plugs, clean with little carbon or with little white. Shifted from bosch platinum, back to the stock NGK down graded the wires to the OEM ones. Replaced the fuel filter and pump all lines and fittings good. Vacuum good. Running out of ideas. Has any body ever had this happen to them or am I the only one. I also think the fuel mileage isnÆt as good IÆm getting like 240 miles or less out of a tank. Is this normal? Everything else checks out good. Brought it to my local mechanic and he couldnÆt figure it out. Any Info would be great IÆm just trying to get this resolved. Thanks Chris

Leaking injector? If it sits long enough, the leaked fuel (leak stops after pressure bleeds off the fuel rail) evaporates or leaks down to crankcase so it's not flooded.
When you do a hot restart, the fuel is still there, and you get a hard start until you clear the flood.
To check, before a hot start, pull the dipstick and smell for gas, or pull plugs and look for fuel wetting.

Another way to test that theory is to try and bleed the pressure out right when you shut it off, let it sit for 20 minutes, then try to start to see if it makes a difference.

Coolant temp sensor, I had a similar problem with my old 4G63T powered Dodge colt. colt start would fire up awesome, but anytime the engine was already warm, had to keep cranking and it would chug up to an idle.

Don't think it's the cts. Bad cts in a 3.0 usually leads to cold weather hard cold starts, because there's no cold enrichment. Usually no problem with hot restarts, unless the cts shorts the two leads together, which is rare.
