Help - Disco 1 cranking but not running

Hi there. I'm looking for some advice for a Disco 1 non-starter. Everything was fine; she would hunt when idling, and the fuel consumption was high, but at least she was running. Stopped at a friend's house in Idaho, and now she will crank but not run. The fuel pump and filter have been changed, plugs have been checked, the ignition module has been changed out, the battery is fine, fuses and relays have been checked, and some replaced. The Onboard diagnostic display only kicks out the error code 02 after disconnecting it. We ordered an MAF and Idle air control valve that will hopefully arrive tomorrow; however, before the issues, we ran her without the MAF, and it was fine. Does anyone have any ideas, as we are running out of time and options before Christmas. Thanks!
