We have changed the head gaskets then the timing chain, camshaft sensor, crankshaft sensor, the coils and the ignition relay. There is not spark also made sure battery is fully charge what could we be missing that is keeping from having spark?

I am assuming battery has been tested for load test and is in good shape. Try another key if you have one not a new one, then make sure the battery terminal ends are clean with no corrosion. Finally try resetting security system there are two different systems on this car another key ois one option and other is in picture. Try that as well.

Did you try what I sent in picture? There are two different systems on this car security wise so I do not know what you have I have sent instructions for both. Is the scanner a auto parts one or professional one? You may a different key from owner if they have one.

The only time the security light is on is when the ignition is off and all it does is flash when you turn the key on the light goes out all the way.

Can you check the oil pressure sender, there is a safety that when the oil pressure drops it cuts the engine off through the ignition system, please double check this sensor.

Let me know what you find.

Best, Ken
