Car wouldn't start couple of times, had to be jumped but started right over. Mechanics ran all sorts of diagnostics but found nothing wrong, batter fine, alternator fine, nothing wrong with codes. That was a week ago and now, it stalled on me today, batter light came on, oil light came on, lost steering but did start but not right away. This is a 2006 Ford 500 with less than 16K miles on it! Very puzzled as to what could be causing these problems!

Usually a sign of something draining the battery.
The machine test probably showed the battery could hold a charge and the alternator was charging the battery.
You may need to have someone check for a power drain.
When the key switch is off, there may be a weak short to ground or a relay or component that is using power.

this doesn't sound good at all. if you couldn't jump start it within a few minutes, you should have stopped right there. maybe you were jumpping the car wrong, from doing so, you may have fried the computer, that rounds your entire engine. try installing a new battery, if any codes were stored in the computer, clear them out. some times just removing the battery cables for a few minutes will do this . sometimes not. try to start the engine. donot jump start, see if will start on its own. if not, seek professional help, keep blaming goodyear until you get results !!!!!!

Get the charging system End starter check out,

All I can say is do some research online find a REPUTABLE shop and let them drive it until it dies. Three things are needed for an engine to run: spark, fuel, compression. I doubt it is a compression problem being that it is a new engine. Something is causing either spark or fuel to drop out, a good mechanic should be able to quickly identify what is missing from the equation. Find a shop with a lab scope that can test sensors that send signals to the engine computer. It could be as simple as a fuel pump getting hot and quitting. Good Luck!

It's the alternator...it is not keeping your battery charged. You can remove it and take it to a local parts store and they will test it for free.

It may be a bad ignition switch.

Also, It could be a fuel pump, remote chance. A fuel pressure test would prove if bad. Should have 40 psi of pressure.

Any warning lights on, on the instrument panel? Check engine light? Or, they come on after the stall?

Hi
Pop into to your local garage and have a diagnostic test carried out.
Listen to the advise given. It may save you lots of money, especially if you start the "guessing" game.
It does sound like a part may be blocked or failed though, but the sytem needs to be tested thoroughly first.
Good luck

IT CAN STALL FROM LAKE OF FUEL OR INTAKE LEAKS THE FAST IT WOULDNT RESTART LEEDS ME TO THINK ITS A IGNTION PROBLEM POSSIBLE BAD CRANK SENSOR, GET IT TOO A SHOP THAT IS GOOD WITH DIAGNOSTICS THEY CANSOMETIME STALL OUT WITH NO COMPUTER PROBLEMS ? BUT DUPLICATING THE STALL IDS SOMETIMES INTERMITTANT IS AGRAVATING TO TECHS SO BE PAITENT , HAVE SOMEONE DO A T.S.B. SEARCH FOR THIS PARTICULAR PROBLEM MAY FIND A BULLETIN GOOD LUCK

sounds like you are putting a bad battery into the car...try a fresh battery.  Batter is spelled...battery

If that is your only transportation you need to call other repair shops. Find out about towing fees and what diagnostic fees they have.

Before there were diagnostic scanners, there were Mechanics. Scanners come in all types and some will suggest possible solutions and others are tools which Mechanics use to find problems.

For instance, you are told you have fuel pressure. You are told they installed new spark-plugs. You were not told if the spark-plugs are getting electricity to fire. You were not told if the fuel injectors are getting electricity to allow gas to reach the cylinders. You can have fuel pressure but the fuel injectors must open to put gas into the engine.

A noid tester or plain testing light will show if the injectors are opening. A spray of starting fluid will also indicate if the engine is not getting fuel despite fuel pressure. It will try to run with starting fluid if it has spark.

When you find out whether it runs, if not, then check for spark if the starting fluid does not make a difference.

It is questionable whether new spark plugs were needed if installing them had no effect. Check other service places.
