Trail Blazer crank but wont start.
Replaced all 6 spark plugs, It cranks. SP manufacturer (AC Delco) says do
not gapped. Engine crank as new but no start. It was perfect before spark
plugs got replaced. Just wanted to have them replaced as preventive
measure. Besides that I noticed that a clear fluid is leaking after cranking. it
is oily in consistency. Smell like engine oil. I found that because my kid ball
ran under tha car; after that, tried to reproduce the dripping by cranking, and
dripped some more. I have never had any oil nor fluid dripping from thie
vehicle. Concern 1: Engline not starting. Concern 2: oil dripping.
