BONE HEAD mistake, now what???

[Sign Guy]

So, I finished puting my new head gaskets on and try to start the thing. Slow turn over several times and then I get a small back fire that was strong enough to blow the vaccuum lines off of the IAC and vacuum advance line. Realized that I have installed the distributor rotor 180 degrees out of phase . Put it in correctly and now it turns over just fine but will not start. What have I fried??? I checked all of the fuses. It was originally showing error code 02 prior to getting the motor to turn over correctly. Now it is not showing any error codes. I've got power to the coil and it is getting fuel from the smell at the tail pipe. What should be next step be; new MAF, new distributor, set air gap or something else???

THANKS!!!
