Engine Mechanical problem
1998 Chevy Blazer 6 cyl Four Wheel Drive Automatic 200K miles

the engine will turn over but will not start or hard to start must turn it over many times before it starts changed fuel filter and cleaned coil and it started ran for a while but now will not start again

Hi:
When you have the no start problem, have you checked for both fuel and spark? If you have both, you may need to check the engine's compression. Let me know so I can further advise you.
