Question about 1999 Lincoln Navigator
When you turn on the key to the Run position you should hear the fuel pump go on for 2 or 3 seconds and then shut off. If you do not hear anything, the Inertia safety switch is probably tripped. This switch would be behind a panel in the rear cargo area. Most likely paired up with your Air suspension switch. There is a button on the Inertia switch which resets it. Push it and hold the button a second or so and then leave the hatch open.
Go try the Keyswitch and see if the fuel pump now makes the noise I told you about. If it does start you car. Then shut it off and replace the panels you removed and shut the hatch.
If this does not work you will need to determine whether the engine is getting any spark. There is also a pressure fitting for a gauge to check fuel pressure. Hopefully you will not need to go any further.
