My truck has a hard time starting after its been sitting while I'm at work or overnight. It seems like the pressure bleeds off. Thought it was the pump or regulator, so changed it out, regulator and pump since the regulator is on the pump, and it worked good for 1 week starting right up on the first try then went right back to the hard start. Once it starts, it runs fine. I can stop at a store, shut it off, come out and start it right back up. Only when I let it sit for a long period of time, its has a hard time starting. What should I be looking at next?

This is really strange. The issue is fixed. I replaced the water pummp (not related to this issue - but was leaking from weep hole). I put back together still would not crank. The battery seemed low, so I switched to an x-tra battery from my boat. The truck cranked right up. I checked the alternator (14.5 volts) its good. I switched the batteries back to the old one. The truck cranked right up again. My wife got me an Innova 3130 scanner tool. I hooked it up, still no codes. I have test drove three times, no issues and acts like nothing wrong.
I probably should suspect a crankshaft sensor/or bad battery will show itself in the future. Will have to wait and see, but no issues in the meantime. Very Strange?

Most likely suspect is a leaking fuel injector. You have to pull the fuel rail off with the injectors still connected, then watch for one that's leaking.
To aid in starting, turn the ignition switch to "run", then back off, then to "run" again, then crank the engine. Each time you do that, the fuel pump will run for one second. Doing that multiple times is needed to get the pressure up for starting. During cranking, battery voltage drops quite a bit so the pump will run rather slowly. That makes it harder to reach the pressure needed.
If you do have to replace an injector, it is suggested they all be replaced at the same time. Rebuilt injectors are sold in flow-matched sets. Chrysler buys their injectors from Bosch in flow-matched sets so they have extremely little trouble with them. GM doesn't check theirs. They just toss in a handful from a bin of injectors, then, with high mileage, they start to flow different fuel volumes and that leads to elusive misfire fault codes even though the engine seems to be running just fine.

Your scanner should also give live engine data. When the engine is warmed up and running ok, write down all the sensor readings, fuel trims, everything. That way you will have some base readings, the next time you have a problem. That scanner should also have freeze frame data, shows what was going on when the problem occured. It's not guaranteed that the scanner will solve the problem, but, a good place to start.

A garage with a pro scanner can do this. But if it starts don't worry about it.

Back to what you said initially
"new battery won't turn over the engine"
Changed battery worked
Changed back to other battery works
Sounds like you have a loose, corroded connection near the battery---you may have "jiggled" you a decent path for the voltage to follow while playing w/ the batteries
If not dealt with/ may let you down again
Think maybe it could be that simple?

Hello to all. The truck has 60,000 miles. The problem is that it developed a prolonged cranking time issue about two years ago when the engine is warm. It starts every time, but it would crank for up to 15 seconds before it would start. When cold, it would fire right up. About a year ago, it reversed itself. Now when cold, it takes 5 to 10 seconds to start. When warm, it starts immediately. It has a new battery and cranks strong all the time. I can hear the fuel pump firing up when the key is turned to on position. Any ideas? If you need more info, let me know. Plugs, wires, serpentine belt changed at 50,000 miles. It does have a very slight, noticed only in the tach, drop in RPM at idle. And it pings like an SOB under load. Dealer says it is supposed to do that. Even gave me a print out stating this. I don't know if this helps, but I wanted to give as much info as possible.

Has a fuel pressure test ever been done on the truck? If the pump is a little weak, then it might not be able to keep up causing a lean condition, and possibly pinging. If it is weak it would also explain the excessive cold cranking
