Hello All,


I have a 2000 Deville DHS. It just will NOT start! History- Was stalling when I would come to a stop. Service Electrical system came up. Took to dealer they said would need new PCM just to even see what was wrong as my computer was reading so many codes they couldn't figure out what was wrong.
THINGS I HAVE DONE
New Starter (before this wouldn't even turn over at least NOW acts as though wanting to AT LEAST try to start)
Had new PCM module installed and programmed not from dealer though as that was a house payment for THEM to do it
Had new crankshaft sensors both of them installed
New Spark plugs






WHAT CAR IS DOING NOW
As stated, acting as though wants to start but nothing. My battery is good, headlights come on. However, my dash lights ARE NOT coming on and dash is completely black. I thought it was or could have been ignition switch, changed that, but to no avail. I am needing help BAD on this one. Only other thing I can think of is having a locksmith come out and reprogram the key to car as this may have happened when putting in crankshaft sensors??? I don't know everything else tested getting spark, fuel,,
