The starter turns the engine over fine. When you release the key and it goes back to the ON position, the starter continues to run, until you manually turn the key to the OFF position. The engine never fires.
The solution to this problem was simple, embarrasing and frustrating. The dome light was left on, and discharged the battery....enough to prevent the ignition from firing apparently. I did not suspect this, because the starter would turn the engine over very well, for a long time, and would do this repeatedly. In all my experience, I have never seen an engine spin that well and not start. According to the dealer, the voltage was too low for the ignition to work. While I do not know the exact threshhold where the voltage is too low to crank, I could have detected the condition by checking the voltage at the battery while cranking. It should have been significantly below 12 volts, indicating a low battery. The tow truck driver who picked it up simply used a portable battery to jump it off and cranked it with no problem. The symptom of the starter continuing to run after releasing the key is new technology with computerized controls, and is normal nowdays. You don't really notice this because the engine usually fires so quickly that it is undetectable.

This vehicle is equipped with a chipped ignition system.On your dash warning lights,when turn key into on position you'll notice a yellow key symbal, it should flash then go out. If it flashes then goes to solid on, it means the system does not recognize signal from key. This can be because of wrong key(original valet key will not start car) or key for whatever reason has been deprogrammed. Which can only be done by dealership unfortunately. If system is working(light does go out) then you need to look at possible brake switch sensor,park/neutral safety switch on shifter, and for signal at started when key turned to start position
This is perfectly normal on 02 and up GM cars The starter will engage and release when the car's engine runs. If you let go of the switch before the engine runs, the vehicle will continue to start until the engine starts. Once the vehicle starts, even if you crank it again, it will not grind your starter because of the anti-grind feature built with that model. Do not worry my friend, your car is fine!
Hi Thomas, First things first. Any time you have an automotive question please include the year, make, model and engine size of the vehicle in question. This will help give you the most accurate information I possible can.
To generically address your problem....
A single click every time you turn the key to the start position usually indicates a bad starter. There are a couple things you can check.
1. Make sure there is twelve volts on the large wire to the starter when you try to start. 2. Make sure you can turn the engine over by hand
If those two pan out than tap the starter with a small hammer while a helper holds the key in the crank position (be prepared for the vehicle to start!). If the starter cranks over replace it.
If its a single click and everything goes dead until you let go of the key and wait a couple of seconds, check the battery connections.
A series of rapid clicks when you hold the key in the crank position usually indicates a bad/weak battery.
Let me know if you have any further questions and I'll be happy to answer them. Thank you for using Fixya.com!
Check the dash once you turn the key to the run position the passlock runs a security check using a set resistance value through the chip in the key. If the security light begins to flash the reading it received was incorrect or it didn't get a reading at all. You can try reseting the value it is looking for by turning the key to start then releasing it. After 10 minutes turn it off then cycle it start again leaving it in on for 10 minutes then back to off then one more time. After the third cycle has completed for a total of 30 minutes. You should be able to turn the key on and start the vehicle. If the light continues to flash their is a problem with the chip in the key or the connections within the ignition its self. Both are common but a Pass Lock Relearn as described above will usually adapt to the poor connection values. Hope this helps.
ricks63toy, I believe that Ford still uses what is called an inertia switch even in the hybrids. This switch will shut off in the event of an accident shutting off the fuel pump. This is a safety feature built into the vehicle. Seeing that this is a newer vehicle I trust that you still have the manual. If not, the switches are usually located in the trunk. Look on the side walls of the trunk and see if you can locate it. It is usually marked by a sticker. When you find the switch, push the red button down until you hear a click. This will reset the switch and allow power back to your fuel pump. Good luck with this.
Its very rare to have an ECM go bad and still have the vehicle start and run.
The vehicle will start itself meaning if you turn the key to the crank position and let go the engine will continue to crank until it start. This is completely normal.
If you have an extended crank condition where it takes longer than normal to start the vehicle especially after a hot soak (the engine is fully warmed up, you swing into target for 20 minutes, and then try to start and it takes longer). This is usually caused by loss of fuel pressure. Two common problems that cause this are the fuel pressure regulator and the fuel pump.
The component is a
starter. When you insert your key into theignition and turn it, you switch on the power to the coil and vehicle
computers. By turning the key to the start position it will supply power to the
starter and solenoid which cranks the engine until you release the key allowing
to return to the ignition on position.If the battery is weak the starter solenoid may engage producing a
clicking sound, but it will not crank the engine. Another test is to turn on
the dome light and try to start the vehicle, if you see the dome light dim when
you are trying to start the car the battery is weak or the starter has a short.
Starters are temperamental at times and can be intermittent working sometimesand malfunction other times. Your ignition
switch, fuse, or relay could also produce symptoms of your vehicle not
Can you actually hear the pump run? On most vehicles it is not good to drive a vehicle with gas under 1/4 tank before filling up again. makes the pump work harder and can cause the pump to go out. When the pump goes out the vehicle will not turn over
