Disco 1 Non-starter

[FierceMelon]

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 she just won't turn over. 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!

I am presuming you are dealing with a 94/95 Disco I since it doesn't sound like you are OBDII. You say it won't turn over, but I am going to assume it turns over, but just doesn't fire.

If you were running rich you may have melted the CATs this will cause the engine not to run as well. Have you checked spark?

checked for spark, all good. Update: I tried the override on the immobilizer with the key code 1515. She ran rough (it's pretty cold at the moment), switched her off, and tried again. She's now a no-go. Should I try and bypass the immobolizer and try again?

Sounds like the spider alarm has gone bad. I believe there is a way to bypass it completely, but dang that has been a while. I am sure a google search will get you there as well.

I would also try locking and unlocking the door with the key 3 times to see if it resets.
