2011 Tahoe starting issues

[Kjv42]

Cranks over good. Used to pop off right away. Lately it’ll hesitate a bit before running. Runs good after that. Changed plugs and wires and still hesitates. Any ideas? Thx

Sounds similar to Andy's. Still doing that after changing the vent valve Andy?

Does it start any faster if you prime the fuel pump a couple times before starting???

Turn the key to the ON position, without attempting to start, 3-4 times then try starting it and see if it still hesitates.

No check engine light and not one starting issue since installing the new Genuine GM purge valve
Thanks James!

That seems to help. What is the fix? Thx

If priming it makes it start up better then it sounds like the fuel pump is weak.

Install a new fuel pump and enjoy.

Make sure you get a good OEM type (AC Delco) pump... you don't want to have to drop the tank again because you cheaped out and bought a ***** pump.

Also make sure you get the correct pump for your application... Flex Fuel or Non-Flex Fuel.

*** EDIT ***

Not sure why "Fuel pump" is blue in the above sentence. I did not paste a link, but somehow it did it on its own... weird. *** It did it again ***

*** EDIT 2 ***

Now "fuel pump" is no longer blue... BUT AC Delco is... what's really going on... lol

Thanks for the reply. Will definitely go with a quality pump.
