Hi guys, I had a short yesterday while wiring up some fog lights and now the car cranks strong but isnt starting. When I turn the car on/acc mode I do not hear any fuel pump noise so I am thinking its a relay.
Initially, ODB fuse and radio fuse were burnt but replaced but still no start.
I just can't seem to find where the proper relays are for the fuel tank and/or EFI relay to try and replace or test it.
I checked the owners manual but no mention of these relays and online I seem to find different answers on where these relays are located: I did test every fuse and relay I could find/access and ALL OF THEM tested fine. I am lost at this point and wondering if its Ecu?

Thanks for posting this. My wife's 07 Malibu had the electric power steering make her trouble too. The symptom in it's case was that the steering wheel would suddenly jerk slightly to the left or the right. pretty dang spooky! Local Chevy dealer put in the new motor, total about 800. 00 plus (9 years ago. probably much more now (2020. The important thing to know with these electric steering systems is that they draw a LOT of power, so you MUST HAVE A VERY POWERFUL FRESH BATTERY! Our battery has become somewhat weak without our realizing it and the low available current destroyed the motor. Moral of the story. keep a fresh battery in these cars.

The power steering module is part of the electric motor? I have a 2012 Buick Lacrosse Hybrid throwing all kind of codes. And just like you experienced no communication, I had to disconnect the 12 volt battery to be able to pull the fault codes. But in my case no check engine light on just completely possessed! Key locked in the ignition doors won't unlock and transmission locked in park! Rumor has it that the Powertrain module are notorious for going bad. In my case a lot of contact cleaner on those three plugs and all seems ok for now. the upper connector seems lose and I notice it was brittle. But seeing this video I'm questioning my diagnoses.

Aww The poor kids. Was it your Birthday? Sept 29th? You Could Have Paused the Video for 5 mins Dude! They were so Excited to Bring you all those Gifts and Surprise You! You Just kinda blew them off to keep working. If that experience ever happens again Please 'Do Yourself' a Favor and Drop Everything I don't care how much YouTube is 'Paying You'! Give the kids their attention and glory. Thank them for what they did and the thoughtfulness of the gifts and greeting. Even if or Especially if they are not your kids! That part of this vid made me very sad.

Hey Eric, I don't understand something here. If this unit takes 60 AMPS, how is this unit saving gas mileage? 60 Amps has to be steeling about 5HP from the engine at the alt. and a power steering pump is about that or less, why go to all this mess at all? Most cars will only see 1 PS unit in their lifetime and a replacement is far cheaper than this electronic thing. I am baffled! ?

Wow! Great Video! 500. 00 for that P/S P. O. S! This C. A. F. E. stuff is killing us. A pump on the engine did the job just fine!
On top of that, the P/S unit has NETWORKING! Isn't that just special!
Well, thankyou for showing this one, increasing our learning curve!

Tell the owner to go to GM and complain. 06 steering motor should be covered by the extended warranty. I have a letter for my 06 to that effect. The electric power steering seems to fail more for women. I suspect they hold them against the stop too often.

You are so screwed if that module goes bad! NO START EVEN! Great if your at home, screwed if your M I L E S from home and no traffic on the road! Should be a bypass for the network to jumper from the BCM to PCM to get the vehicle home!

It sucks that the hardware was probably good, you had an electronic module failure that brought down the network. No wonder there is a core refund, they can simply replace the electronics and then sell it all to the next guy.
