Tip & How-To about Chevrolet Chevy
A lot of times i see in here "my car won't start" or "I put new plugs in it and it still won't start". If it is petrol engine you need fuel (gas at the right mixture with air) in the right amount, a spark at the right time compression in other words the when the piston comes up to the firing time the valves are closed and there is no air escaping past the piston rings or blown head gasket ( low compression). If one of these things isn't happening it won't start.
It is a process of elimination, Check for spark then gas then timing, you may have a spark but at the wrong time and last of all compression test, most engines won't start under 60 lb psi.
