Suburban not starting

Asked by JHorne7106 Mar 04, 2019 at 09:23 AM about the 2002 Chevrolet Suburban 1500 LT 4WD

Question type: Maintenance & Repair

I have a 2002 Suburban
1500. Over the weekend
I changed all 8 spark
plugs after that the truck
ran fine so Sunday
morning when I got to
start it it will not start.
Its turning over but not
starting. Does anyone
have a clue as to where I
would start and what to
start with when it comes
to checking things?

Make sure battery has a full charge and connections all good. Have a helper crank it while you check for spark at the plugs. If spark everywhere, use a gage and check proper fuel pressure and fuel injector pulse. Any applicable trouble codes?
