Default No Start

Two days ago I was driving and the "ses" light started flashing which I knew was a misfire. I had been having trouble to get the car started, hesitation problems now the car won't start. It turns over but seems like I am not getting a spark. Took a quick look at the fuel injectors and doesn't seem like any of them have popped out,loose or any gas spraying out. I pulled all the spark plugs and replaced them and still no spark. Turned the key to "on" position and I heard the fuel pump and noticed that there was fuel on the spark plugs. Pulled the spark plugs again and noticed they were black which means I am running rich. Used a digital multimeter and tested the coils 1/4 had 5.08 and 2/5 & 3/6 6.05 replaced the coil and no change. Took the ICM off and went to local auto parts store and the guy tested it and said it was working fine. Rechecked the coils with the new pack on and got a spark of 5.67 on 1/4 and 2/5 & 3/6 spark of 6.17. Seems like first pack is short again which I can't explain why. Also, checked the dipstick and no milk like color.

Notice there is corrison on my ICM which I will clean...

Bad ICM the problem?

Are you checking at the coils or at the plug wires?

At the coils... coil test

How do you test the wires? If my one my wires was bad wouldn't the car at least start...

The black on the spark plugs actually doesn't indicate anything if you aren't starting. If the car were running and they were black, then I'd agree. W/o starting though you are simply not getting a complete burn.

Pull the plug wires one by one and have a friend look for spark jumping around from the wireless post when you try to start it. You should have a good spark at each post.

How old are your wires?
Check fuel pressure.

My thought here is that you are missing spark, timing or fuel. The little fuel you saw on the plugs may be misleading. If we have fuel, our engines can run on 3-4 cylinders. They will run poorly, but it'* possible. This makes me hesistant to think only one coil is causing you not to start.

I would say 7 months old on the wires...

So pull the ignition wire and see/listen if I can hear a spark trying to connect with the plug correct? I also read that you can remove the spark plugs with wire attached and touch ground if I see blue spark.

honestly, If you take two plugs off the coil, They should shock each other. Sounds Like the Crank shaft position sensor. But check the fuel p/* at the rail, Make sure your injectors are working.

I don't know if this helps at all but this first started a few days ago the car had trouble starting..cranked it a few times and finally started... drove the car a few miles and it started misfiring again.. pushed on the gas and the car shut off but the lights were still working. Wouldn't turn over and I changed the front 3 spark plugs and it cranked right up, ran good and no problems then the next day it happened again now it won't start at all. I found out that coolant was running down my fwi and into air filter which was soaked in coolant. I have changed the gasket since the car has been down.
