Hello and thank you for trusting us with your question. I'm DJ.

Is this a 4 cylinder or 6 cylinder?

The first thing I would check is to see if the distributor is turning when the engine is cranking.

Then test the red and black wire that goes to the coil and see if it's got 12 volts power with the key in the RUN position.

Next thing is to check E1 in the DIAGNOSIS connector. This is a 1" by 2" box next to the fuse box under the hood. There's a chart inside the lid that shows what each of the terminals is.

Check the voltage on this terminal with the key in the RUN position and the negative or black lead on the negative post of the battery. This is very important, not the sheet metal or the engine.

Let me know what the voltage reading is and we'll go from there.

What about the the red and black wire on the coil?

This is the power supply to the ignition coil.
