I am having a problem with keeping the car running. I can start it and it will run very poorly for about 5 seconds and then die. The exhaust also smells like gasoline. This was a spontaneous problem. The car was driven 2 days prior without issue. I came back out to go somewhere and I experienced this issue. I thought it was spark, and I have replaced the ignition coil. But if it runs at all it obviously is getting spark. I have no oil in the coolant or coolant in the oil (not head gasket). I have unplugged the MAF, swapped the IAC with another spare, swapped the cap/rotor, and checked the timing (pulled #1 and spun until it was at the top and rotor pointed correctly). I read that it could be an EGR vacuum regulator sticking or a loose wire. I haven't had a lot of time to tinker with it. I was going to swap the plug wires in case they may be arcing. Any other ideas?
