My 1999 Discovery 1 (U.S. Spec), GEMS - 4.0 / V8 - Gasoline, will not start!

Engine is cranking strongly - just seems like there is no fuel getting to engine.

Believe the immobilizer has activated somehow!

Checked:
Battery / Alternator / Vacuum Lines / Immobilizer switch on firewall in engine compartment / all fuses - engine compartment and inside drivers compartment / Coil / Spark Plugs (all working properly) / fluid levels / vehicle has 1/2 tank of fuel / both fuel filters new as of 1 months ago

NOTE: Have driven vehicle for about 1 month now with NO issues!!!

Also ran diagnostic (using HawkEye) of actuators - all working properly!

Checked Security settings (because of immobilizer possibly being activated somehow) using HawkEye Tester programmed for Discovery 1

Following is what each screen showed / question is: are each of these settings correct and if not, what should they be???

In addition: Can anyone advise me (crayon style - LOL) on using the configuration option that is available in the HawkEye Menu? What exactly does it do / how it works / warnings or words of wisdom and If I should even use this option etc.

Any advise would be greatly appreciated in relation to the above stated situation and additional questions about the "Configuration" subject!

The truck will not operate the starter as part of alarm inhibit. Also the LED on the dash should not be on. If immobilized, from RAVE: LED Continuous: Driver’s door open (or ignition on)
and immobilised. So if no light, you are not immobilized.

The multifunction relay on passenger side fenderwall, just aft of the ECU, has two fuses in the fuel pump circuit, plus the inertia switch. Push top of inertia switch to reset. You can meter at these points to see volts to pump, or remove fuse and insert an amp meter to see amps. My D1 draws about 5.1 amps for the fuel pump. The system does not run pump forwever, just long enough to bring up pressure if truck is not started. If engine does not start, pump times out anyway. You should be able to measure fule pressure at the rail on passenger side, or at least depress schraeder valve with a rag and release fuel - about 30 - 34 PSI when running.

Do you have spark when cranking? Can test by a hand held tester that lays against the cable, or pull off a plug wire and attach to a spare plug and lay on mainfold. See Amazon.com: Lisle 19380 Spark Tester: Automotive
If no spark, the crank position sensor is highly suspect. I enclosed an attachment for the D2 (same sensor, ECU, better write up). The CKP sensor may not throw a code if it fails.

As for the Hawkeye, the factory is your best source of info.

 

Thank you for the insight. Will follow your directions and hopefully it the true problem will reveal itself. Your assistance is greatly appreciated! Will advise of results.

Thank You!!!

And YOU???

 

Well, been a long day. I believe that the issue may well be the camshaft position sensor. Hat tip to Savannah Buzz for the quick assistance and getting me pointed in te right direction. Hope to have this resolved and everything back to normal next weekend after I return from Italy. Will keep you advised and once again, thank you.
