Question about Mercury Sable
While driving my 2002 Mercury Sable's engine will cut out. While the lights and clock stay on, the radio and engine turn off. When this happens the battery light, ABS light, and a cog with a '!' in the middle turn on, and the wheel locks up. For the most part, after a few seconds of coasting it starts back up. Any ideas what the problem could be?
The battery light would come on because the engine has stopped running and the alternator is not charging the battery. The steering would get difficult to turn because the engine would not be turning the power steering pump. So those things would be expected.
It sounds like you have a relay that is failing, or you are loosing power from the key switch.

your radio is staying on? you have a bad door switch.the bcm does not see door opening and thus does not turn radio off. most likely the drivers door.

You describe this as an acceleration problem however, if the car does throw a check engine light it should be recorded in system memory so it can be pulled by scanning with and OBDII scanner. It sounds as if the car is being starved for fuel on acceleration. Check the fuel lines for kinks as well as check the fuel pressure. The problem could be a faulty fuel pump that has yet to completely die.

Hi, I had the same problem. it is the imoboliser, it reads a code in your key while starting. you need to get the code in the key reprogramed. if that wont work you will need to get a new ignition barrel. Audi dealer will reprogram your key.

If the battery and alternator tested fine. I would have the charging system rechecked when engine is hot and at high rpm's. This way the checks are being done as if you were driving and driving for a long time. Alternators can work fine when cold but weaken when hot or stop working. This problem is not rare but only is seen occassionly. Unless it was checked at an electrical shop the average shop doesn't run these tests for they don't see the problem often enough to automaticly run them at all times. Good luck and let me know how you make out.

the lights come on and the power steering goes because the engine has stalled while you are driving. it is the exact same condition as when you turn the key to the "on" position w/out actually starting the engine (all the same lights will be on and no steering because engine not running).
as for why this happens...sadly there are too many possibilities to usefully list here.
This is the basic equation for why your engine runs:
fuel + spark + compression = a running engine
The fact that your engine usually works means you can discount the compression piece of that equation.
This leaves fuel and spark. If loss of spark is the cause of the stalling, it is almost definitely in the primary side of the ignition system which means: don't go get a 'tune-up'. Tune-ups almost never-ever-ever fix driveability problems. The primary side of the ignition system consists of the crankshaft position sensor, camshaft position sensor and engine computer...to name a few things.
It is also possible you are losing fuel pressure intermittently, which could be due to a failing fuel pump, but this is an unusual presentation. Typically they are found to be bad when you try to start it up initially rather than **** out in the middle of running.
Then again, this whole thing could very possibly just be due to a loose wire connection in a really unfortunate place. Impossible to tell from here, so you'll probably have to settle with taking it in somewhere. I will say this: don't waste time/money taking it to a shop until it absolutely will not start up again. Shops can't diagnose a problem unless it actually has the problem while they are looking at it. good luck
