Testimonial: "i pulled the wires, one by one, then when i found one that did not change engine sound, i pulled the plug and found good spark. Also, oil is coming from valve cover hose to air filter. I have also been dealing with water in the gas for several days, which was causing power loss and sputtering. Draining fuel/water seperator would temp. fix problem, allowing me to continue up river at full power"
If cylinder getting spark not firing not getting fuel.could have plugged fuel injector or faulty fuel injector.i would use a noid test light see if fuel injectors getting power and firing.hook noid light to fuel injector electrical connector need a helper which crank engine while you look at noid test light.if test light blink pcm is working.steady light pcm not firing.no noid light means fuel injector electrical connector has short in wiring or connector.you can buy fuel injector noid test light at auto parts stores if not snap on tools has them.

SOURCE: thick blue smoke. no oil
Hi! Chris, There are many causes of oil burning or exhaust smoke. There are three different causes of normal oil burning, 1; worn valve guides (smoking during deceleration), 2; worn cylinders and piston rings (smoking during acceleration), 3; split or worn out valve seal, or damaged intake manifold gasket (smoking all the time). Of course there are several variables in this equation. Sometimes coolant can also get into a cylinder and cause a blueish smoke. If you remove the spark plugs and use a pressure pump on the coolant system (radiator), coolant should leak into the intake manifold or cylinder. Coolant leaking into the intake manifold will leak into several cylinder through the valves. So, what year and how many miles are on the Jaguar?

You may consider tracing back from coil back to the main plug and checking wires going into and coming out of the plug for any broke wires make sure to look for collapsed casings sometimes the wires will break internally
