My Cadillac security light

Hi Joan Whittaker,what does no crank mean.
the starter motor is dead? some posters call d crank= running engine.
which engine there? cranks fast but will not start.
underhood fuse box f24 blown?
step 2 after all fuses checked is:
shift to Neutral see if that allows cranking per my red circle below
is PCM control.
is the dash IMMO lamp happy?

as you can see the pcm decides to do the cranking or not
via its starter relay.
if you scanned the PCM it will tell you why it id not start.
immo error OR A/t PRNDL (TRS) ERRORS. OOPS




the IMMO page in your users guide covers IMMO
if key 1 fails try key2, car came with 2 keys new.
READ ALL PAGES ON IMMO FIRST

If the engine does not start and the Security System
Light comes on
Security System Light (CLUSTER LAMP ICON LOOKS LIKE CAR CUT IN HALF WITH A PADLOCK, never ignore this lamp.
This light flashes when the Theft
Deterrent System has been
activated.

sounds like you need to bring the car into caddilac to have the passlock systen (security) reset, these cars can be very sensitive to battery loss

Is the security light lit up on the dash when it wont start? If so, you have a VATS security issue. The system will actually turn off the starter if it feels that it is being stolen. It thinks its being stolen when the chip in the key doesnt communicate with ignition/lock cyclinder. Or if the security computer is going out. (it's called the TDM) If that light is on, its a dead give away that the vats is messed up. If no light, id try a good charge on the battery. Sometimes the lights will work fine but you dont have those cranking amps that you need to start.

Have the battery checked. It sounds like it is just a junk battery.
