01 disco 2 I had to replace the radiator core support and had to bleed the ac in order to get it off. Everything got put back together right, but when going to start the vehicle i ran into this problem. I borrowed an obd reader from the auto parts store and it reads "No Powertrain DTC's or Freeze Frame Data is presently stored on computer" I cant get it to pull any codes. Any help would be appreciated! Thank you.

 

You have described a tripped inertia switch. No fuel and hazards are on when it is tripped. Push it and try again. Big black button on firewall over above the heater core area.
Make sure battery is charged

 

ya that was the first thing i tried, sorry i didn't include that in the original text. I even bypassed the switch and nothing. It sounds like a communication issue because prior to this i had a code or two but now the code reader isn't picknig up any codes?? Is there something i can do to rectify this without towing it to the dealer?

 

Shrader valve on the driver side of the fuel rail. You can stick a pressure gauge on there and see if you get enough fuel
