1996 GMC Sierra Z71 K1500 5.7 ltr 144k miles

I am having problems starting the truck. Right now if the vehicle sits for a couple of hours it will not start unless I spray some starter fluid in the TB. THere are no diag codes. Have checked / replaced the MAF, MAP PVC. But once the vehicle is started it runs like a champ. If it does not sit long it starts right up. Thought maybe it was a tank of bad gas have run fuel injector cleaner thru the tank. Have not replaced the fuel filter yet. Any suggestions........

Thanks in Advance

Check the fuel pressure. Sounds like a leak down while it sits.

If it is leak down, it should start right up if you turn the key on, wait about 10 seconds. Turn it off a few seconds, and back on for 10 seconds and then crank it.

Hey Al, Thanks for the tip. Tried that, but still did not work . I do not have a fuel pressure test kit. Trying to save a little mula by fixing myself but might not have the tools or the knowledge to give it a go. might have to break down and take it to the shop.
