Save your self time and worry, do compression test right away on all cylinders, if you don’t have tool or don’t want to pay, simply put butt end of plastic screw driver or broom stick and turn key, you should feel the air spurts on each cylinder and compare with each, if your missing compression you should know right away, rule that out and it becomes easy, spark plugs, coil, injections, wires
