Default Immobilized??? No start

99.5 disco 2. Auto, sunroofs, seven seats rear AC. No start, alarm light is functioning as it should. Could the no start still be from the immobilizer? Ran normal but a few blocks from home my radio went out for a second no other signs, parked and sat a few days then no start. Turns over but won’t fire. No codes or check lights. New relays, new fuel pump makes noise when trying to start. No change. New battery cable clamps. Power to all fuses. Swapped BCU and ECM along with IDM, no changes. Key works to unlock doors. Pulled a spark plug wire has spark when trying to start. At a loss!!

Default No psi??

I don’t have a gage, so took cap off and pushed the Schrader valve no pressure released. Also found the cruse control hose was disconnected/ split.

if no pressure at valve then fuel pump is a good bet. Cruise control hose is irrelevant to this issue.

So i retested for pressure after trying to start a few times. Did get a squirt of gas this time. Also jumped the inertia switch that didn’t change the no start. New fuel pump. Is it possible for it to be immobilized if the lights not flashing? I tried to do the 1515 turn the key procedure but couldn’t get it to accept it. I can lock and unlock with the fob just fine. No alarm light when trying to start either. Not sure what Im missing.

Lock and unlock three times, preferably with the fob. See if it will start.

Yes tried that a few time with fob with the dash lock button and with key in door. Ordered a new crank sensor. Going to try to swap that again. Had a non Bosch one in it now. The tech doesn’t move when trying to start it either.
