I have a Lincoln LS that won't start but the battery is fully charged.

Asked by magnesium88 Jan 07, 2013 at 07:43 PM about the 2003 Lincoln LS V8 Sport

Question type: Maintenance & Repair

The engine will sit there and turn over all day long, but doesn't actually "come to life". My room mate
is pretty mechanically inclined, and I am not so shabby myself. I can change the coil packs no
problem as I am sure anyone else who owns this car can. Here is the deal. I ran my car two days
before this started happening with absolutely zero problems. Two days later I come out and the
battery is completely dead. I charge it for 4 to 5 hours. As I am charging the car the first few times
the horn & lights start to flash. After I put the key in the ignition to get those to stop I left the car to
charge. I come back to it and all the normal bells and whistles come to life (lights, seat, steering
wheel, etc). Turn the ignition and the car won't completely come on it is like it is trying to turn over
but doesn't completely get there. From all my reading the past couple of days on this issue I am
thinking there might be a problem with the PATS. Could this possibly be the case? Possibly the Inertia
Fuel Shutoff Switch?

Sounds like it is in the security system on your car to me. Had a simular problem on a gm and we replaced the relays and still nothing we would jump the synoid and it would turn over but would not start. Had to bring it to a shop and they had to disable the security system by by passing it or they could replace the ingnition switch was cheaper to have them by pass the security system.

It was the inertia fuel cut-off switch located behind the kick panel on the driver side. Very easy access. primed the pump and the car started right up damn PATS. Live you learn I guess.

I started having this problem a few years a go, after short trips. The dealer attributes it to a design flaw of the single wiring harness, and the battery location in the trunk. Not enough power to actually start the car. A new battery has helped, but for days without use, and in cold weather -still need to charge battery or jump start the battery.

My 01 lincoln ls would just click after replacing fuel pump and battery, the clicking notice was coming from fuse box under the hood, which happens to be where the starter motor relay is located,( it's #15 ), so I swapped the relay for starter, and blower motor places, and car started right up, so if you experiencing the problem of won't turn over,and just clicks, and your red security light goes off when key is left in on pisition, try replacing #15 relay under the hood... hope it helps

Anybody know if whether or not you could jump your battery and start the car if its not starting due to a disabled starter circuit from the anti theft being triggered on a 95 lincoln town car? Sometimes it wont start but will turn over so one day when it wouldnt start, i replaced the fuel pump relay and it started but then started back acting crazy. So i took out the relay and then out it back in and it started. After doing some reading im wondering if im somehow triggering anti theft which is causing it not to start but when it does this, all i have to do is have someone jump my battery and it starts right up. Can you jump start a car if it wont start because the anti theft is triggered?

I have a 2002 Lincoln LHS V6 (40k original miles)/California vehicle with same 'won't start/won't turn over" problems listed above by everybody else. California vehicle. Fuses/relays - check good Inertia Fuel Shutoff Switch - check - good Fuel Pump ? Such has been the case with this car for the past 8 months... Just for the heck of it I decided to start the car early in the morning - 2 two days ago expecting the same - and it started/turned over! Kept the car running for 30 minutes. I decided to repeated the same procedure 6 hours later (noon). FAIL. Won't start. Next morning repeat exact procedure - early morning it STARTS. 6 hours later (noon) FAIL. Again this morning, Same as day before... Seems to turn over when I start in the morning. Weather this week since the start of this warm sunny days, evening very cold. What to do now? I appreciate any insight that anybody can share regarding this. -Peter
