Starter relay on 2001 Town Car . Replaced ball joints, now it won;t start

if the car won`t turn over then it could be a starter problem if the battery is as you say fully charged. check voltages at the starter. it could be a bad connection or starter relay.

Hi Adeline,The lower ball joint is an integral part of the lower control arm. If the ball joint is defective, the entire lower control arm must be replaced.So here's a link showing you how to replace. http://www.autozone.com/repairinfo/repairguide/repairGuideContent.jsp?pageId=0996b43f821a44bb Here's another link to a new part.

Check the starter and the starter relay or fuse. A client of mines car was doing the same thing, it ended up being two issues, the starter not working anymore, and a relay that was bad. If I am not mistaken everything should be labeled in the fuse box under the hood and will tell you where the fuse/ relay is for your vehicle

the relay should be located in the fuse panel near the battery in the engine compartment

Two things to try, If you have a second origional key try that first. If the problem still persists, you will need to take the vehicle to a reputable garage to have the problem diagnosed. You could have a bad key and the theft deterent system is causing the problem or it could be a bad ignition switch or start relay.

THE LOWER BALL JOINTS ARE A VERY TIGHT PRESS FIT INTO THE ARM, YOU NEED TO BUY A BALL JOINT PRESS KIT TO REMOVE THEM, BUT BASED ON MY PAST EXPERIENCE IT IS BEST TO JUST REMOVE THE LOWER CONTROL ARM AND HAVE A MACHINE SHOP PRESS THEM OUT AND THE NEW ONES IN, IT IS VERY EASY TO DISTORT AND RUIN THE CONTROL ARM DOING AN "ON THE CAR REPLACEMENT", THE BALL JOINT PRESS KIT RUNS ABOUT $50-$200 DEPENDING ON THE MAKER AND THE QUALITY, TRY WWW.HARBORFRIEGHT.COM TOOLS FOR AN ENTRY LEVEL KIT.

Check the the park/nuetral switch. Check power at starter relay.
