ABS Bleeding
 

On a 2003 Grand Marquis I suspect I have air in or needs new ABS pump. How would I bleed one and what scan tool would I need? Thanks.....

You didn't mention your symptom. Air will not enter the system unless it has been opened for a repair or the master cylinder ran dry because of a leak and air got in. However, you can flush out the old without a scan tool provided you don't let the master cylinder run dry and pump it.If you are having a spongy or low pedal with good linings, I would suspect a bypassing master cylinder than a faulty ABS module.

Another post, hide and run, never to be heard from again till the next mishap.

Reminds me of the old song from WW2:
"There Ain't Nobody Here But Us Chickens!"
I guess we can't expect a lot of action on a forum for cars that haven't been made for over 10 years.
The juice ain't worth the squeeze.
