Have 99 disco salty editon which would run for five or ten minutes and then engine would shut off. let it cool for fifteen minutes or so and would crank right back up. Now it will not start, the fuel pump is not pumping and there is no spark either. Had a diagnostic plugged in and it threw a code for crank sensor and antitheft. So does anyone have any idea which it could be, and ideas? Tried to read codes again today and i wouldnt even show a code it showed computer locked

 

Search for crankshaft position sensor. 30 minute fix and only two bolts.

 

Ditto, you have a bad crank sensor that is shutting of your fuel and spark.

 

post in the correct section next time.

 

I agree, this is a specific question and if you want more feed back post in the Discovery 2 section.
