ABS light

Hi I have a question hopefully some one can help. I recently picked up a 1999 malibu 3.1L starting yesterday my ABS light comes on. this is when it happens, I start the car everything is ok the ABS light is off. as soon as i drive 10 feet the ABS light comes on. I shut off the car and re-start the engine And the ABS light will be out, i drive 10 feet the light comes back on again. it happens every time. i assume it is a speed sensor at one of the wheels. How can i tell which one it is with out replacing them all one at a time.

Most likely a bad wheel speed sensor, a scan with a abs function scanner will pinpoint the problem.

Thanks maxwedge my scanner does not have ABS feature. is there a way to check each sensor with a multi meter do you know what ohm reading i should have.
off topic is that a 64 fury it's hard to see in the pic. is it yours? i have a 69 roadrunner 440 my best friend has a 65 sport fury convert. we cruise them to carslile every july

Rear about 1030 to 1137, ft is 1020-1180. But sometimes they will pass this test and still not work.

Also, be sure to check the wire harness. The left front sensor was bad on my 98, but it turned out to be just the wire harness. Spliced in a new connector years back and all has been well.

UPDATE PROBLEM FIXED
ok i finally got my friend over with his snap-on MT2500 scanner. we ran a scan for the ABS it came up with 3 possible causes
1- bad ABS relay
2- bad ABS control unit
3- Alternator putting out more than 17 volts causing abs control to malfunction
And the winner was....
#3 bad alternator at idle output was 15 volts when i hit the gas it would jump to 17.3 volts i replaced the alt and all my problems went away.
With out the snap-on scanner i would never would of thought of the alternator causing my ABS troubles.
