Re: 1997 Buick Lesabre - oil on spark plugs

I would be more suspicious of a leaking valve cover.....a cracked head? Who came up with that one?

I assume the vehicle is cranking over ok, and just not firing?

I seriously doubt, oil on the plugs is causing a no start......

Have you checked fuel pressure? Have you tried to start the car by spraying carb cleaner into the intake?

Have you tried starting the car with the MAF disconnected?

Pull the vac line off the fuel pressure regulator and look for fuel in the line.....

Have you checked for spark and injector pulse?

Have you checked for codes?
