I had the same problems one time it was a starter relay and the other time it was the purge valve. Purge valve makes it seem like you losing power and theyll start and drive, but when the purge valve doesnt "purge" thats when youll see those problems. When the starter relay goes bad, you go to start your car, everything turns on but the engine. It wont crank or anything but your car turns on, radio and dashboard. Im paying for a sts v8 right now because the owner before me didnt take care of it, but thats life, lets keep these lac's rollin and strollin!
Anyone with a tech2 or mdi and a computer with internet access can program it for you. You just have to pay GM’s fee, but that gives you 2 years access for all the computers on that vehicle to program them. Or if you have a friend at a dealership and can get the car to them, you can get the “hook up” may be.
@TOILET DUMPER It’s not the body control module. Unhooking the battery wont work, and with that ratchet button, any time it’s pressed, the starter will run if there is enough battery power for it. All the designed safeties in the system are defeated. as far as the actual issue, it’s in the engine control module. the computer is not properly responding to the wake up command it gets from the power mode master, so it’s not commanding the starter to turn. This particular engine computer isn’t programmed to “go to sleep” for about 45 minutes or so after no driver inputs. That’s why there’s no issue when people come back to the car after short stops and it works fine, but when they go to start it in the morning after it’s been sitting for hours, it won’t start. does that answer your question?
bob robertson a cheap/wannabe LoJack system malfunctioning? I guess that’s possible too for , but the car I was was working on was bought new from Cadillac and was passed to the original owner’s son in law. Never been traded in or to a used car lot. As far as mechs guessing and throwing a computer at it, I’m guessing you mean an engine control module, wouldn’t the malfunction keep happening and the customer figure out the mech got it wrong?
@@hesus2468 if by resetting you mean leaving the battery disconnected for an hour or 2 so the ECM will totally power down, you can try it. I doubt it would work, but I would have tried that.
I don’t know if you’re even gonna see this but it’s worth a shot..Did your car start at all before this guy came in and ran another wire N button?Cause I’m having a similar issue but if I play with the ignition switch on and off the car would start I was thinking it’s a faulty starter until I seen this video..
I just went out to car and it has been sitting for 4 hours and shouldn't start normally. I got in and used the key FOB to unlock the doors and then I proceeded to start it. It cranked right up!!! I will keep posting any developements
i have a silver one 05 sts and mine want start its doing exactly like u said . i jus changed mi water pump n alternator belt n etc n tha battery good n charged and it still want start
“People don’t take care of them”. Like putting a jumper in to sometimes start it and mess with the transmission shifting and who knows what else? You can buy the tool with all Gm programming for about $200.00. It’s called a Tech2.
I would just leave it like this my Dad has replaced ecm ($1600) and the same shat happend agian will just run a jumper wire and a second switch and be done with it .....
The starter relay to the button and the button to wear I do the purple wire to the battery to try to start it but it seems not to want to start but the button it might help me out a little bit for now at least to get it good
when you put the ecm in... you have to turn the key on for 10 minutes, 3 cycles.. and the car will reprogram automatically (best use a battery charger so your battery doesnt drain)
What are the odds that I look for a help video and it's my car before I bought it and I was looking at the seats and I'm like they must tear in the same place on all of the and then 😅 I'm like has the same blue wire ran and then when you go around the back I see the phone number and I'm like dude that's my car

@@autokronicles8160 people in the hood and everywhere want to drive luxury model cars. Cadillac, Mercedes Benz, Lexus, infinity, Range Rover but they don’t want to pay dealer prices to have their vehicle serviced correctly. The Cadillac dealer doesn’t give a shit if your Cadillac in new or 20 years old his prices are the same. If you can’t afford the maintenance, you can’t afford the car. Fuck a jumper wire I’m paying the 800 to get my shit fixed right.

Don’t need dealer, u can pull one from junk yard trust me I did it a few times already. Forget the dealer. U might have to pair the ECU with the key 🔑 but that’s it u can do it home no tools needed
@@autokronicles8160 I'm a ASE certified drivability tech working on one right now at a shop. You need to get a wiring diagram. Go through everything in the starter system. This one turned out to be a bad pcm. I installed a used one and then reflashed the pcm. Not saying that's your case.
I'm a certified mechanic also and my experience is most mechanic are know it all as_holes. You can't work on a few of any cars and speak for the whole lot of them, if you wanna know how good a car is look at a consumer reports report on the specific model.
@@Quintos. problem now days is there is a shortage of qualified technicians. Not to many people want to do this work anymore because the technology in these vehicles is difficult to learn, you need a hundred thousand dollars in tools and face it companies don't want to pay.

@@slowpoke96Z28 No i mean pulling the 15 amps ecm fuse.
So everything except the ecm is powered. Ive read thats how you reset it on this car.
Had the same problem send the ECM to a company call Air Bag for $150 they rebuilt the ECM and its warranty for life
ronsee357 wow thanks, I wish I new that then I sold the car!!! Dang it!!
Can u be more specific with the name of the company,I googled air bag but nothing came up,having the same issue with 05 cadillac sts

Atlanta Georgia you you have to send them your ECM and in 2 day you will have it back

I didn’t know they came without dvd players
I had to do is reset the ECM by taking it out put it in taking it out putting it in it will reset itself
Sounds like Jerome owned this car and never took care of it. Keep it crossover and don’t fix it. That’s why I don’t buy cars in this condition
How was the button wired? I need a temp fix.

I'm having the same problem not starting, is it just the wire running from the starter relay to the button?
I would just leave it like this my Dad has replaced ecm ($1600) and the same shat happend agian will just run a jumper wire and a second switch and be done with it .....
Man this is soo crazy I own this car
Where did he connect the button to and how did it disable the ECM or make it work with a button I have the same problem
Edgardo Garcia connected the buttton to the starter relay
The starter relay to the button and the button to wear I do the purple wire to the battery to try to start it but it seems not to want to start but the button it might help me out a little bit for now at least to get it good
I boluy 4 relays and didnt fix shit I have to jump it with cables
Electrical problem draining battery in 1days
when you put the ecm in... you have to turn the key on for 10 minutes, 3 cycles.. and the car will reprogram automatically (best use a battery charger so your battery doesnt drain)
What to do exactly???? Please answer how to do that. Im pissed off
@@michaelbmw1931 did you figure it out? I'm having trouble with mine
Turn the key to on for 10 minutes. Do it 3 times. You have programmed the ECM
This is only for the passlock system not the ecm reflash it is programmed by vin.
It's the push button start
These cars are a pain in the ass
What did he override the connector with ?
Ecm and pcm basically the brain of the car
Fix yellow wire going to the computer,, You have a bad control side coming from the computer
How he put the button up there
What are the odds that I look for a help video and it's my car before I bought it and I was looking at the seats and I'm like they must tear in the same place on all of the and then 😅 I'm like has the same blue wire ran and then when you go around the back I see the phone number and I'm like dude that's my car
