Exclamation 2010 traverse possessed no crank no start no codes

I am offering $30 thru Paypal who can help me fix it or narrow it down to where the culprit is:

story time:

2010 traverse FWD with 170k, you turn the key, all lights come on, gauges turn but no crank, no clicking noises nothing. No CEL. Try a few times and nothing, wait a little longer try it again and it cranks. Sometimes open the door and closing it i get it to start. This going on for almost a year.

2 nights ago, i move the car out of the garage to the curb, starts right off then a few hrs later came back to move it back and it would not crank, tried it about 7 times and nothing. The next morning, I tried it another 5-8 times and nothing, I locked then unlocked the steering wheel and nothing, put in N and nothing. This morning, i tried it another 10 times and nothing but i needed to move the car back a few feet to get it out of the curb so i turn the key and put it on N and push it 5 feet then park then try to start it and it starts like nothing is wrong!!!!

Additional issues at random times:

* While driving once in a while the oil pressure sensor warning comes on then it goes off after a few miles.
* while driving once in a while and a person in the passenger seat with their belt ON, the car rings to put passenger seat belt on.
* while driving once in a while the transmission does not shift out of 3rd gear so i have to pull over, turn it off then back on then continue to drive with no issues.

Things i have tried:

* I replaced oil pressure sensor, same issue with the OPS(no oil leaks either)
* old battery checked and recharged and same issues
* replaced with new battery and same issues
* unplugged onstar unit and nothing
* check and cleaned battery cables and nothing
* unplugged battery while running to test alternator and it works, car doesn't die.
* tested for blown fuses and visual check relays and they all look good
* i gently wiggle the ecm harness during the no start in the past and nothing
* cleaned MAF sensor too

Took it to the dealer about 4 times and since they "cant" replicate any of the issues and no codes, they havent been able to help me!!!!!!

I am pretty mechanical incline so if you have something for me to try and know the steps let me know and i will give it a try and if it works, ill send some beer money your way!!!

I am planning a new and reprogrammed ECM but before i pull the plug I wanna hear it from you all.

I also have had the traverse since 75K miles too.

Doing this- can cause issues on these modern cars.

The Body Control Module (BCM) may be damaged if the module is supplied with battery power when the ground path is removed on some vehicles. The negative battery cable should be removed first before removing a BCM ground on 2006-2008 Monte Carlo; 2006-2011 Lucerne, DTS; 2006-2012 Impala; 2007-2009 SRX, Equinox, Torrent; 2007-2010 OUTLOOK; 2007-2012 Enclave, Acadia, Silverado, Sierra, Avalanche, Suburban, Tahoe, Yukon, Yukon XL, Escalade; 2008-2010 VUE, H2; 2008-2012 CTS, Express, Savana and Traverse models.

When the BCM is powered up (key in the Accessory or Run position) with the ground ring terminal removed or loose, the BCM will attempt to find a different ground path to the vehicle. This different ground path attempt may cause internal damage to the BCM.

The following systems controlled by the BCM may be inoperative or work intermittently because of an internally damaged BCM caused by a lifted BCM ground:
•Interior lighting (will remain on or will not work)
•Exterior lighting (will remain on or will not work)
•Remote Keyless Entry
•Door locks
•Power windows and mirrors
•Remote vehicle start

Refer to Bulletin #07-08-47-004D for additional information. Models listed in the bulletin and not referenced above have the BCM ground wires going directly from the BCM to the ground ring terminal.

The BCM,ECM, all computers HATE loose, bad, corroded connections of any kind.


Be very careful, these little jewels are costly.


Corroded battery cables and bad,or "going" bad batteries are "generally" the culprit, but you've already checked...right?

Was ANY work done to the vehicle by yourself or a mechanic prior to this happening almost a year ago?

I replaced the battery with a new one even though i was told the the "old one" was still good.

All cables look good, no signs of corrosion either. At the battery that is.

Dealer "fixed" a hissing noise at the AC due to a "possible" leak in the ac lines inside the car?

Warranty work, done about 3yrs ago.

To my understanding they had to take the whole dashboard apart to "get" to the lines and replace them.

U ever heard of a Loadpro? As vehicles age electrical problems increase causing all sorts of problems, especially bad,corroded, loose grounds. Difficult to find.


Go on U Tube and plug in Dan Sullivan's Loadpro. Watch some of his videos.


Some vehicles are "born" with inherent bad electrical problems. IE: my 2001 Dodge 2500 diesel. Nothing but electrical problems from the first day I drove it home right up to now. For no reason it recently has"developed" a case of no headlights. The engineer who designed the wiring for the headlights outta be strung up by his thumbs. Just my extremely humble opinion.

Does the security light behave any different when the no start happens? See below. It’s a padlock/car symbol:

It sounds like an intermittent issue with the key chip reader. Open up the steering column and check the connectors, wires going to the key cylinder. Try to start it and keep retrying while you wiggle/tap/ move the wires and module and see if it starts. If it does you may have narrowed it down to the culprit system. When they put it all back together after disassembling the dash, things may not be lined up right, could have a pinched wire or a damaged reader. It reads the chip by proximity so if the reader is not installed right it may be in and out of range slightly.
