jump started another car with my taurus now the taurus won't start . Taurus was not running while jumping the other car. Went to move it now it won't start. Cables were hooked up correctly. What could have happened? All fuses look ok.

Does the starter crank the engine? Do you hear the fuel pump run for a few seconds when you turn the key to run?

No offense but would be nice to know what you are driving. what year, what motor, what
make, sedan or wagon ? If you didn't use the proper jumper cables ( and jumping ) the newer cars is not recommended. Without seeing the car you probably
blew something up. Need a lot more info.

sorry......2000 taurus sedan 3.0 engine. Jumped my 99 Alero ,Taurus was not running while jumping. One quick hit of the key and the Alero was running. Just had the cables on for a minute. Was getting dark so I did not spend much time on it. Did not check for fuel pump activity. Turns over but will not start. Did check fuses and found all to look ok

First thing I would check would be how tight the cables are on the battery posts. Mechanically, that is all that would have been touched. Getting to electrical, if the Alero gave off a pile of voltage when it started, it could have poked back into the Taurus, with possibly disastrous effect. The T has a KAM, or keep alive memory, in the ECM that is connected to the battery as long as the cables are connected. If you had a good surge, you could have eaten your computer.
Check for pulses at the plugs, check for pulses at the injectors. If you don't get any, and they would be the computer providing ground to the injectors, and ditto to the coil packs, your computer may be fried. You should also take a look at the PATS indicator on the dash if so equipped. The Passive AntiTheftSystem flashing light should stop flashing while/after you crank it. If it doesn't, then the key has not been recognized ..... coded again into the computer memory... whistle whistle whistle...
Good luck.
