i've used the search but i'm new at this and don't know what to check first. my car was running fine. the only changes i made were to:
1. add about 7 oz of Power Service Diesel Kleen to about 15 gals of fuel;
2. change a blown fuse (#7... backup lights, heater, etc.)
3. add 1 pt. Synthetic ATF because the ATF was low

then... (about 2 hours later)...
i drove the car for about 15 miles and could feel a noticeable difference in shifting and acceleration. after about 20 minutes, the antilock light came on so i tested the brakes to make sure they were working-- which they were.
after turning the car off, i tried to restart it and got nothing. No starter grinding-- nothing. The SRS light, lights, heater, and all the battery stuff worked, but from the outside you could not even tell that i had turned the key.
any ideas on how one of these things could have triggered this or does it seem to be something else that is unrelated??
