Engine dies or looses power door locks lock and unlock. No codes, checked wiring and grounds all look great, replaced crank angle sensor. Looking for any suggestions!

thanks!

I would check your ignition wires first, then check the ecm or maybe bcm?  Maybe just a faulty wire that when heated up loses good connection, then cools and is serviceable again.  I start here because of the fact you are not throwing codes.  At the very least if it was a Crank Position Sensor you would get a code for it.  Same as any misfire.  Low fuel pressure should not cycle your door locks.

Crank angle sensor has been replaced, Im thinking the voltage regulator in the alternator is getting hot and the output gets too low, when it dies the message center says “ Battery not charging” . Ive got a alternator on the way.

thanks for the reply!

I didn't think of that. I'm having the same problem one 2092 silverado. I've changed ignition wire, fuel pump, fuel filter, crank positioningsensor. I'm likebwtf

      2027 GMC Sierra: Official Discussion

      By Jus Cruisin · Posted

      I was the GM of a Lincoln Mercury dealership back in the 80's. The service lot was always full with "broken" ones. Plenty of transmissions, power windows and a/c repairs. The only one I'd consider owning would be the Marauder at this point and it certainly wouldn't be a daily driver.  My 2025 GMC Sierra 1500 Denali Ultimate is my "Lincoln Town Car" in my retirement. I want all the "stuff". Big infotainment screens, one touch power windows, Supercruise (I won't buy another vehicle without it), hands free pretty much everything. I'm going to swap my current truck for a 2027 Yukon Denali Ultimate so I can have the air suspension and surround vision recording along with all the other "stuff".

      The Denali Ultimate's grille is tinted, but the "regular' Denali has a bright chrome grille like the current models.

      Because that is IDIOTIC, much like this question. They've already been forced to do it by past administrations - why would you roll that back when it's a GOOD thing?  WHO IS ARGUING FOR LOWER MILEAGE???? 😂  NOBODY IS!!   I'm certainly not! What I want is RELIABLE vehicles again that are worth the price paid!    I don't get your logic here ...   In 2003 I paid $2,200 for our '86 Grand Marquis. It's STILL running and I've never been inside the engine, aside for the timing cover since it was leaking, so I threw a new timing set in since that makes sense. Transmission is ORIGINAL. Electric pump in the gas tank is ORIGINAL. Rear end is ORIGINAL. I'd have to hit my head REAL hard to want to pay $60k or more for a car that still can't come close to the comfort, seating and storage space, or reliability of this one. Nothing is even in the ball park! Hundreds of thousands of brands and models have been built and sent to the crusher while this one keeps on going!   https://postimg.cc/Z9XRrCSg   I've got a whole fleet of cars, motorcycles, and a truck close to this age for summer and winter. No one could pay me enough to buy anything built this century. I have zero use for any it.

      Since I'm the one who has to fix them when they break, I'll take vehicles over 30 years old all day, EVERY day, over ANY modern crap. Have you attempted any repairs on anything built after 2006? It's a friggin nightmare, and gets worse the newer the model year.    If I had the will or desire, I can make any car of any age outside of a Model T (I don't have THAT much will ...) just as powerful, comfortable, and have all the tech the new stuff does, and get pretty close in mileage, too. I prefer SIMPLICITY. The less the vehicle has, the less to fix WHEN it breaks, not IF.   I'm glad you snot-nosed punks don't like them. More for us, plus that keeps the prices from climbing more than they already have.👍
