99 continental wont start when cold

Hello,

I have a 99 Continental and if the temperature outside is below about 38 degrees the car has trouble starting when cold. Its fine after the car is warmed up, or if the temperature outside is like 40 degrees or warmer everythings fine. Any thoughts?
 
RE: 99 continental wont start when cold

Would it be possible for you to be a little more specific?

What does "trouble starting" mean?

Does the engine crank over slowly?
Do you need to boost the car?
Does it crank strongly but not fire up?
Does it crank for only a second or so longer than normal?
Do you have to keep turning the key off and retrying?
Does stepping on the throttle help?
Does it start, then immediately stall?

All of these symptoms are important clues to narrowing down the cause!

For a few examples:

1. If there's an apparent randomness to your "trouble starting" (some days you only need to crank for an extra half-second, other times you crank for so long you're sure the car won't start at all), it's probably the single most common Continental starting problem:

"It is very common for 4.6 Continentals to lose CKP (Crankshaft Position sensor) signal to the PCM. Without CKP, the PCM is unaware the engine is rotating. It will not provide spark or injector pulse. It also will rarely set a code because the malfunction occurs only during engine cranking, not run.

The CKP is a magnetic sensor reading a trigger wheel behind the harmonic balancer. If you look to the rear of the balancer, you'll see a small 2-pin connector to it. The sensor is held in place with an 8mm head bolt.

The problem may not be the sensor itself, although that's fairly common. It's often simply minor corrosion on the pins in the connector.

As a matter of fact, Ford TSB# 97-14-5 provides instructions to use DeOxit or similar contact cleaner (available at any Radio Shack) on the terminals and applying a coating of silicone di-electric paste in the connector to prevent further moisture intrusion.

It's often as simple as that!"

2. If stepping on the throttle ~ 1/4 of the way down helps make the "trouble starting" easier, you need an IAC (Idle Air Control) solenoid.

3. If cycling the ignition on and off slowly 3-4 times before cranking the engine over makes the "trouble starting" go away, the fuel pump is probably bleeding down overnight and needs to be replaced.

...or perhaps you meant the Theft light is flashing and the car won't recognise your key...

Thanks for the reply,

It cranks over at normal speed. it trys to start right up like normal but as soon as it starts to start it dies. if I keep on cranking it will start after about five more seconds. If I give it a little gas when starting it will start right up and stay running. So yes stepping on the throttle works.No check engine light. It started up fine all summer but now that the weather is colder I am having this problem again. It started last winter. Its not that big of a deal but I was just wondering why it does this and if it can be fixed. once I get it started if I shut it back off and start again it starts fine.

Check item # 2: if helping it with the throttle works, 95% of the time it's the IAC (idle air control) solenoid. It's mounted on the side of the throttle body and held in place with two 8mm. head bolts.

Very easy to replace.
