Question about Lincoln LS
Won`t start right up when the car sits for 3 or 4 hours or the first start in the morning ,cleaned air volume control valve, new crank senser, could it be cold start senser if so where is it located?
Check fuel pressure and temperature sensor on air intake.

No such thing on your car.
The temp sensor tells the computer what the engine coolant temp is.
If it were faulty you would get a check engine light.
I would have the fuel pressure checked before and after you crank the engine. The pump relay provides power to the pump when you turn the key on to recover some of the lost fuel pressure after the car sits. The one way valve in the pump is supposed to prevent the pressure from dropping.
If the fuel pressure drops to zero it could take some time to crank the engine enough to get it back up.

remove the air filter housing from the throttle body, or if its mult-ported injection, remove the large air duct. Do this the night before. The next day, before cranking and having a spray can of carb. cleaner, spray a couple of shots of carb cleaner either into the large air duct, spray towards the engine, or if its single body injection, spray directly on to the throttle body.
Crank engine immediately, preferrably have some one else sitting in the car to start it after you spray.
If the car even tries to start, replace cold start relay.

SOURCE: Long cold cranking before start
You have a very common problem; your fuel pump needs replaced. Inside the outlet of the fuel pump is a "check valve", that holds fuel pressure from draining back to the tank. What you have happening is the fuel has emptied from the lines and the injector rail; the long cranking period is the time that it takes for the fuel to be pumped back to the engine. Replace the fuel pump & your problem will go away.

Hello carol...from the symptons you describe more than likely it's the CPS (crankshaft position sensor.)
The CPS is a common problem on Cateras with these symptoms.
The sensor is a magnetic impulse type that sends a signal to the computer, the computer then triggers the fire signal. When the CPS gets weak, dirty or has low voltage the intermitten no starts occur. It will finally result in a no start at all...Please be aware that a lot of caddy dealers will and have overcharged customers for this common problem by ill advise and replaceing uneeded componets.
Good luck...i hope this helps and will fixya up.

Problems with a new car should be under warrenty. Take it back to your dealer as attempting to repair it may void your warrenty and cost you big money.
