I'll try to include as much detail as possible...
The car has 77k on it.
Tried to start the car two nights ago. I thought it started, so I let off the key and it did not start. The car started right up on the 2nd try, but was misfiring and /or running rough. The check engine light came on, flashing and then solid and then back to flashing. I let the car run for a while thinking it would smooth out. It did not. I decided to turn the car off and try starting over. Now the car will crank, but not start. I can hear the fuel pump prime. I checked one post on each coil pack and I'm getting spark on all three. I checked the fuel pump relay which seems to be working. All fuses were checked as well. All are OK. I have had no problems with the car until this point, but I've only had it 6 weeks. So much for the 30 day warranty. When I took off the aircleaner assembly there seemed to be collant in the throttle bore and in the cold air intake tube. There also seems to be collant leaking out of the EGR discharge tube and onto the top of the transmission. (Not sure of this is related)
Thanks in advance for any help/replys.

Pull the plugs for inspection you may have coolant on them also. This sure sounds like the infamous upper intake manifold (UIM) leak, where the EGR tube has burned a hole in the UIM. We have many threads here on this subject and you can do a search to find more info. If you have any problem using the search function, let us know.
