Well, car stated sputtering on on my daughter yesterday. She had the codes pulled and it was p0300 misfire. When the first plug wire was removed the entire end of the plug wire was covered in oil (dripping). So I told her to have her boyfriend replace the plugs and limp the car home. The car did not make it and her story of what happened on the way home makes no sense. As she was driving she lost the power steering and brakes. She had to use both feet on the brakes and both hands to steer, in order to get the car off the road and stopped but it was still running when she finally got it stopped. So she says. So I replaced the following:

1. A V cover for the oil leak.
2. New plugs.
3. New plug wires.
4. New coil pack.
5. Crankshaft senor.

Why do I still not have spark? I hooked up my spark tester and there is no spark. The car turns over all day long. The plugs smell and are wet. So I am assuming fuel supply is not an issue. I Have even reinstalled all old parts and still have no spark. What is going on? New parts = no spark, old parts also = no spark.
Do you
have the same problem?

Hello,

I would start by checking the fuses f16 f6 and f4 In the fuse panel. Here is a guide to help and the fuse locations:

If the fuses are okay please check the main relay.

We should also run the codes to see what comes up.

Here are the engine wiring diagrams so you can see how the system works.

Please run down these guides and diagrams and report back.

Cheers, Ken
