Help! Is this a stuck injector or a bad coil pack?

[casper_talon]

Hey people, hope you can help me. Well, my car started fine on the morning, ran great to school, then when I was looking to park it, I was idling for about 1-2 minutes, and the car got real rich(had to rev a few times and let the clutch slowly at about 2000rpm to get the car moving). It did this every time I stoped. Then, I shut it down. About 4 hours later, I went to start it, and it did like it was going to start, but died. Then it just cranked, and a heavy fuel odor came. I took out the spark plugs, they were black and smelled like fuel. I bought 4 new ones, changed the coils, and the spark plug wires, tried to start again but the car just said no. I left it there, the next day I went to start it again, and the car started fine. When I got home, shut down the car, and tried to start it again, the same thing happened, gas smell, just cranked. Can this be made by a stuck-open injector, or is it coil-spark problem? Could it be the ECU? The car is a non-turbo, but it has a turbo fuel pump + re-wire & relay, and the pressure is at 45-50psi when the car is running. Thanks for any help you can bring me!

Sounds like a spark problem, or maybe an ECU problem, but most likely it's not going to an issue with a stuck open injector.

I will check that out. It's just that I changed the coils, new spark plugs and wires, and the problem remains. I will check the ecu to see if it's that.
