2002 DTS Deville Won't Start - Please Help
 

Replaced the starter and battery as both needed replacing - today, went to start the car after finally replacing everything and now it won't start. Clicks, key sometimes locks in the ignition, security system bullsh*t, etc. I'm really looking for some insight here, if anyone knows anything regarding this issue I'd appreciate it greatly...
All electrics come on, car is a 2002 DTS, replaced the speed sensor last week also, front control arms, back tires and brakes, plenum, starter, and battery, all replaced. ANYONE have ANY ideas??

Can someone please help, this is really bothering me and it's going on the 4th week that the car has been in the shop.

Check battery positive cable copper wire for corrosion, positive battery post tended to leak acid. Ground connections are a common cause of electrical troubles.

I'm getting all sorts of codes -- C1232, C1254, B3832, B0249, B0429, P0340, P0385 which I've read is the crankshaft position sensor, and C0710, along with U1000 U1056 U1163 etc... All this because I had the starter replaced and a new battery put in..?

P0385 - crank sensor - will cause stall/no start - need both crank sensors for that
hey were redesigned. need to clear codes then recheck see what comes back. some codes are related to low voltage. Do you have Alldata or FSM disc.?

Hey itisian, I have a 2001 dts doing the exact same thing! Where you able to resolve the problem? If so I would greatly appreciate any info you have on solving this problem.
Thanks, cj
