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.
