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.
