My car listed above (300 SEL model) would run for about five miles then stall. It would restart after about thirty minutes. After about eight times of doing this it stopped running all together. I replaced the fuel pump, filter and relay switch. Still would not start, so I replaced the fuel pressure regulator with no luck. Earlier in the year I replaced the plugs and wires and it was running well. I am stuck. Any help would be greatly appreciated.

Thanks.

Hi and thanks for using 2CarPros.com.

Based on your description, it sounds like there may be an issue with the crankshaft position sensor. Take a look at this link.

Check to make sure the engine is getting spark. Here is a link that shows how that is done:

______________________________________

If you determine that the sensor is bad, it is mounted to the crankcase above the starter flange. I attached pictures of what the sensor looks like and its location for you to see.

Let me know if this helps or if you have other questions.

Take care,
Joe
