1999 GMC Yukon hard start

Asked by GuruQWRVY Nov 14, 2019 at 11:52 AM about the 1999 GMC Yukon SLT 4WD

Question type: Maintenance & Repair

Okay this may be odd but i have no idea what else
to do. I have a 1999 GMC Yukon, after sitting all
night i can go out in the morning and it’ll fire right
up and runs great. If i cut it off then try to start it
shortly after its very hard to start, but if i let it sit for
a few hours it’ll crank up just fine. I’ve replaced all
spark plugs and wires, had oil changed and pretty
much a full tune up. Anyone have the same
problem or and suggestions ?
