Ok I bought a 2004 cadillac Seville. Ran very good for 3 days. I pull in to shopping center car cuts off. I try to restart with no luck. Now next day car wont do anything. Check battery 12.6. Check up front at fuse box 12.6. Check all fuses fine. Buy a new starter because the one in it with my unionbox does nothing. Now I am sure its a ground. Dash lights up airbags working. Everything seems in order. Car does nothing. Can you help an old man out here. Thanks. Dave

David,
You should of started a new topic. Maybe an admin will do it for you.
Here is a wiring diagram for your starter circuit:
From your description it sounds like you have 2 issues, stalled & will not crank.Is this one of those starters under the intake manifold? If so, I would start at the starter relay & check powers & grounds. The starter should have constant power to the large cable, switched power to the small wire & be grounded to the engine/trans. Check the I/O's to the relay & let us know what you are missing.
Lets get the engine cranking, then move on to the stalling.
I moved this to your own repair question thread. No big deal, but i did mislabel the title. Trying to change DeVille to Seville, my fault. Sorry about the confusion.

Turns out my number 58 relay was very hot. Unplug the relay but when I put it back it started snapping. Then I could here things coming on. Seconds later I heard a pop and everything shut down. That's were I am. Thanks. Dave

Lighter. Really. This isn't my first. I am 63 but I worked on these northstars when no one would. Been a while. The poping noise stopped everything. Nothing works not even dash
Noise sounded like it came from trunk. Thanks

Do you have power on any of the fuses in the fuse block under the rear seat?

When you say "black on them", are you referring to a stripe? Or, do the have black on them because they have been burnt?
What about the Underhood Fuse Block? Is there any power there? If not, what about the battery?

Is this with the Key On? Or, off?

Dave56. The dummy with the cadillac Seville. 2004 Northstar. Was driving to store when car just shut down. Cranked but no start. Towed home. Started checking my fuses seem fine. Next I checked voltage. 12.7 battery went to the front 12.7. Put the key in and nothing. Sometimes dash lights up and sometimes nothing. Went to fusebox in the back. #58 relay was hot . pulled it out then put it back. Relay started poping. Looking for ecm . looked under glovebox don't see it. While checking on that something turned on under dash drivers side. Seconds latter it shut down . where is the ecm please. Lost and found. Thanks

Don't be too hard on yourself.
I think the PCM is under the air cleaner box in it's own compartment.
