2nd startup is almost impossible.

I can walk out to the truck, stand outside of it , insert the key in the ignition switch, and start the engine in 1-2 seconds. It idles well, although it goes from low RPMs to high RPMs, while sitting and idling. Shut the engine off, wait a minute, try to restart, and the engine cranks and cranks until it almost starts to wear down the battery. Then if you get in the vehicle and hold the throttle wide open, it will start, like a flooded engine and after coughing and sputtering, will return to a somewhat smooth idle. Code reader says 15. Can't believe that a coolant sensor could cause this problem. I'm leaning to the FPR. Any thoughts?

Fuel pressure is 58 PSI. Pulls down to 55 after 15 minutes. Makes me think fuel filter is a little plugged, and maybe having a vacuum issue as vehicle is loping after starting and idling. Going to change filter.

Have a vacuum gauge, just hadn't bothered to try it. Also gonna do the propane test. Have had problems in the past with the Vac 4WD actuator under the battery, having a bad diaphragm. Gotta check that too.

Update! Did vacuum test, propane test, smoke test. All results were negative. Replaced the coolant sensor,,,problem solved. Had a hard time locating sensor and a harder time replacing it. It's tucked in behind the A/C compressor, in the intake manifold next to the gooseneck. Removing the compressor was the only way that I could get it out. Also got a further education. Believe the code reader. I guess you can teach an old dog new tricks. Thanks for all the help and suggestions.
