HI there,

To be clear it's a no crank no start issue?

Automatic or manual transmission?

Customer: replied 1 year ago.
Expert:  Mike V. replied 1 year ago.


When you try to start it, do you hear any sounds at all?

A single click or series of rapid clicking?

Customer: replied 1 year ago.
It acts like it wants to turn over

So, the engine IS cranking and just not starting?

When you crank the engine is the security on solid or flashing?

Customer: replied 1 year ago.
Not sure. Not at home with car. What could be the issue with either way
Expert:  Mike V. replied 1 year ago.

If it's on solid or flashing, then the immobilizer has the fuel shut off. It's a fairly common issue on the 99's. The key loses it's programming and the security system shuts you down.

It could also have a bad fuel pump or possibly issues with a cam or crank sensor. Security is the most common problem however. If that is the case, then you need to have the keys reprogrammed. This can only be done by the dealer and sometimes a mobile locksmith.

That being said, if the light goes out when you turn the key on, then we have to check it for fuel and spark. This is where those other sensors come into play.

If you can let me know late, I can assist you in which direction to go.
