2005 yukon denali gas goes in slow and check engine light is on it tells me to tighten fuel cap

It may be a loose fuel cap or it is worn out already. Check also the hoses leading to and from the fuel tank for loose or bad ones that need replacing.

Had my check engine light checked at a autozone and came up with a u110c... Any ideas for this code?

Code u110c ( no fuel level) Remove the gas cap from the van. Reinstall and make sure to give the gas cap a full 5 to 6 turns. The code set in the system was set by the gas cap not being tightened enough or a faulty fuel cap. If it continues to reset code then replace fuel cap on van. Hope this will help.

1989 1/2 ton 6 Turns over strong won't start.

Have you double checked to make sure that you have fire at the plugs? Remove one from the engine, plug it back into the wire and lay it on top of the engine. Turn over the engine and watch for spark. It should be blue. If it's orange that is a weak spark and new plugs and wires are in order.
If you have spark then you will have to check your timing, because if you have fuel and spark they aren't getting together at the right time. Make sure you have the wires on the cap in the proper sequence, starting at number 1 cylinder. It should be at the 5 o'clock position looking from the front and go 1-6-5-4-3-2 clockwise from there. Cylinders 1-3-5 are front to back on driver's side and 2-4-6 are pasenger's side. An in-line 6 should be 1-5-3-6-2-4 and number 1 would be 6 o'clock.
If it still won't start then line the bottom pulley up so the timing marks are lined up an d pop the cap to see where the rotor button is. It should either be on number 1 or off by 180 degrees. A full rotation of the engine should line them up. If the marks are off by less than180 but more than 3 or 4 degrees you probably need to replace the timing chain. It's not uncommon for a GM to jump time when you shut it off. If it's off a little bit you could turn the distributor to line the button with the cap and it should start then. Hope this helps.

1998 gmc 4.3 starts up but loses power 3-5 mins later,will restart and run again for another short time,fuel filter has just been replaced.

Install a pressure gauge, start and run 3-5 minutes and watch the pressure. You should see the pressure maintain as it did when first started. If it begins to drop, the fuel pump has gotten weak and is starting to fail.
Let me know what you find.
