I know it's not the timing chain.... it's turning over fine and has compression. The plugs look fine but does have some oil deposits on the threads of the plug. It's getting fuel...and it even sounds like it wants to start for like a 1/2 a sec.... but never does. All the fuses are fine... so I am thinking that it may be the plugs have fouled out and need to be replaced along with the wires. Problem is .... is that the back 3 plugs are impossible to reach. Does the throttle body cover have to come off or can the engine be tilted out like some cars?
