Question type: Maintenance & Repair

Hi , I see a lot of good people getting
great help , I'm having a problem
with my 2003 Cadilac Deville , one
day fiancé is at the bank with it ,, it
ended up stalling , it has a few other
times recently and it had a light and
most likely the CPS ,, so she try and
starts it and she gets nothing , dash
lights on but no crank and no start , I
went down and try to turn it I got a
clock in front , think it's possibly the
starter , q mechanic friend of mine
and myself replace starter , from
Napa box covered in dust say sat a
while possibly looked good in box ,,
put in and nothing ,, can't seem to
figure it out , also replaced the upper
intake gaskets because we had it out
anyway , but now trying to figure out
if it's just a bad factory starter , or
something else , Relys are testing
fine , but cranked again and got the
click , also when turn key dash light
cone on but dim out on full turn ,, still
working on this as we speak , any
thoughts or ideas , pleasaasee help

CPS. That could be camshaft position sensor or crankshaft position sensor. Do you know which it is? But let's back up. Sounds more like a battery or battery cable corrosion and/or ground

Not sure which one yet , hooked it up to read codes but will not read ,, bad ground ?? But prior to starter situation running great no idea or pre- warning ,,, and the battery is reading 12.4 volts ,, and no corrosion at all , very clean under back seat ,, very clean caddy all together ,, really at all loss and could use any ideas , also tested the relays ,,, there was a bad one but that is switched out also ,, also can't get a start by banging on the starter either ,, just trying to give as much info as possible ,,,, thanks guys

Well think I have it figured out , we will know 100% today but found the ground wire that connects to the bottom of the alternator box , and leads up and connects to the body was broke ,,,, so explains this mystery hopefully ,,, !! Will keep you posted , thank you !!!
