Engine Performance problem V8 Two Wheel Drive Automatic 137000 miles

I was driving my car and it shutdown on me. No warning and I wouldn't have known for sure, but I couldn't accelrate and the steering was out. I was able to park, but when I tried to restart car, the engine wouldn't turn over. The electric looks fine as far as everything powering up.

WHen you say it won't turn over, do you mean the starter doesn't work or the engine won't start.

Let me know.

The engine won't start. The car was running and it stopped. I tried to start it up again and everything happened except for the engine finally turning over and starting.

I need you to check for spark and fuel to the engine. One will be missing.

Here are the how to's for doing both. Let me know what you find.

This is an old thread but I have seen many people having problems with the crankshaft angle sensor going out in this car.

Here is a guide that will give you an idea on what to do with the repair.

and

Here are some diagrams of what it will be like on your car and how to test the sensor (below)

You will need to jack the car up safely as well

Please let us know what happens and upload pictures or videos of the problem.

Cheers, Ken

Driving along and without warning the engine dies out (no service warning dash board lights), crank the engine one more time, car starts with just enough power to get out of the street into a safe park. The engine dies out again, already change the spark plugs, had battery recharged, no start. Battery did not fully charge up to 630 cold cranking amps, maxed out at 547, but engine turns over very rapidly as before previous time, before this problem. Please provide your assistance, and thank you for taking the time help me. Thanks
