Gas tank got close to empty today, and the fuel light came on. After about 20 miles, i pulled into Texaco and filled up. Put the cap back on and pulled away. No more than 2 minutes went by and my Check Engine light came on. (GRRRRRRR). No obvious symptoms, but the light is on. I pulled over and double checked that the cap was on tightly, and was able to turn it few more times. ( i had heard if its not on all the way the lack of pressure will cause the light to come on??) any ideas?

its a 96... how can i reset it without taking it to a repair shop for ODB2 hookup?

The only way to reset the MIL on a OBD2 vehicle is with a scan tool.

More than likely the light was caused by the gas tank cap not being tightened all the way. Turn it until it clicks a few times. If this is the case the light will go out in a few days. I think it takes 30 (not sure, but quite a few) warmup/cooldown cycles. Give it some time before you pay someone to reset your code. OTOH if you are in the Chicago area I can reset it for you if you want to drive by my house.

If it happens to be a D2, it could very well be because the cap wasn't screwed on well enough after the fill. I can't tell you the technical reasons, but this happened to me a couple of times. The Service Manager asked if we had made sure the cap was screwed on past "three clicks". On the next fill up, I made sure it was and the light didn't come back on. Obviously, this isn't the only cause for the light, but it can be a really cheap fix.

If it was caused by the gas cap not being tight, it will. Mine did, anyway.
