    Are you saying you replaced all of the ignition coils over the plugs? If so what trouble codes did you have in the Electronic control modules memory to prompt throwing away perfectly good parts?? I guess you must be suffering from tunnel vision on this problem, but listen up! you need to check the trouble codes with a scanner for code reader for the OBD2 control system. Any problem like this will leave a path of trouble/fault codes. In your case I suspect a problem with either the CKP (crankshaft position sensor) or the the camshaft position sensor. Don't waste any more money on parts until you have the codes and have done the appropriate diagnostics. This car has very complicated electronics control systems, and throwing parts at it will just frustrate you and seldom fix the problem. As to what fires the Ignition coils, well that is the electronic engine control module (called the PCM), it gets the information needed to fire the coils from many sensors, the crank and cam sensors are the primary ones. I am a factory trained Ford dealer service technician with 20 years in the field, trust me i do know what i am talking about here.

The only way to know what is the cause of this is to have the electronic engine control module scanned for fault codes. It is the very 1st thing that MUST be done.

SOURCE: lincoln ls keypad codes

i have a 2005 lincoln ls v8, my code was on a sticker located under the center of the dash (driver side). i laid down on my back with a flash light and looked behind the radio, you will see several stickers with numbers on them. i wrote down all the number from each sticker then tried them , it worked i found the code. note: the one sticker that my code was on had several numbers in front of it that i had to eliminate ex: 1003(98501), 98501 was the code for my door. it took me 20 min but it was worth it . the dealer wanted $90

SOURCE: Where is the inertia switch on an 04 lincoln ls?

It is not in the trunk. It is on the left side, in front of the drivers door, just above the floor mat. Side panel if you want to call it such. What problems are you having? I have the same veh and all the manuals including wiring diagrams.

You will need a OBD2 code reader, that will give you a "trouble code" then that will tell you what direction to look in, for the problem.

Got a 97 Honda civic ex and it won't turn over,

It appears that the longer time to warm up is because there was no water in the radiator and running for 30 minutes would cause the motor to seize. Check it out.

Security light flashes and won't start 02 lincoln ls

How old & what condition is the battery,on an LS
they only seen to last 4.5 years

Try only one Ford- approved PATS key that is programmed & you know has been working & nothing else nearby, such as a key chain
with other objects

Does the LED indicator flash rapidly or glow steady for 3 seconds,
with key in Run or Start ,if so, you got problems & will need a scan tool to get the codes,not a code reader.

Does the starter turn over the motor?

Need at least 2 keys programmed to system

You got at least 7 fuses to check on 2 of the 3
junction blocks (fuses)

2005 lincoln ls has 1500rpm idle when started would like to adjust it down

The idle is controlled by the PCM, there
is nothing to adjust,it is all drive by wire

Does it go down to 750 rpm after about one minute
from a cold start ? About 1200 cold-- that is normal
Are you in a hurry-- let the car warn up, it won't run on
O2 Sensors for about 5 min until warm

Make sure your using 5W-20 full syn oil every 4,000
miles at most & change the power steering fluid & trans
on all veh every 3 years-- if you want them to last

I have a 2004 LS V8

Do you have stored codes ?

Have you had other issues lately ?

Is the battery original if so replace it,
that is your problem

Have to get battery from dealers parts counter
as it has a vent for the hose out of trunk

The price is on the web site & is not discounted to
repair shops

I think I paid $119.00 in May but i pay no tax

My 2004 Honda Pilot ran fine then a hour later won't start. At first thought battery so we charged up usig one of those chargers you plug in. Lights flicker, and clicking sounds but won't turn

Check batry terminals are secure & free from corosion, check security of earth strap to engine & main power wire on starter, if ok have the batry load tested to ensure it can perform under load as the starter needs a lot of current. Have you tried a jump start?

What's your problem?I have a 2000 Lincoln LS that runs great when driving but as soon as I stop and sit a minute it cuts off. I have noticed the car start stalling a little before it cuts off. Cou

Generally speaking, the common reasons for stalling are a faulty idle air control valve or a dirty throttle body.
The computer controls idle speed by how much air is allowed into the intake thru the throttle body.
Those two issues would be checked first.
Is the check engine light on when the engine is running ?

2001 lincoln ls wont start with v-8 engine

When you say it won't start do you mean the engine will not turn over with the starter like in a dead battery type of no start, or do you mean the engine cranks over fine but doesn't start? If the latter is the case check the fuel pressure, the test port is on the top of the engine and looks like a tire fill valve, it should be at least 45 PSI while cranking the engine over, you will need to buy a universal fuel injection fuel pressure test gauge from the parts store, about $20.00 should do it.

I started my 2004 lincoln ls and turned it off.. 10 minutes later I turned the key over and everything powers down when I try to start.. I tried to jump it and nothing happens.. Please help

Does it click when you try to turn it over? If so it sounds like a stuck/bad starter tap the starter with a hammer while someone tries starting it.
