I'd be very suprised if it is the ABS unit. That would mean all 4 circuits have somehow become blocked.
Do you have an ABS fault light up?
The 5.3 ABS operates using 2 different 12v supplies, key operated supply to pin 15 on the multiplug and and constant supply to pins 17 and 18. Worth checking the fuses I guess but power failure should disable the system for safety reasons and the v/v's will all be open.
What year / version is your car?
