hey bud. So your fuel issue.

im having stabilitrak issues. 2008 Tahoe. Also having issues with crank/camshaft position sensors. I’ve replaced both twice Check engine light keeps randomly coming on and throwing the code for one or both of those. A lot of times check engine light comes on with no drivable differences noticeable Then whenever the stabilitrak pops up while driving I have issues. I can’t ever recall if it’s blinking or solid. I’ll try to pay better attention in the future. But sometimes it stalls and does instantly. Sometimes it runs like crap like it’s only hitting on a couple cylinders or robbed for fuel. When it does that I hear a poping in the engine or maybe a knock. Sometimes I can shut it off and leave it for 15 minutes and it starts fine. Sometimes I have to disconnect the battery for five minutes and then it’s fine. Sometimes cheating the code and it’s fine. Code is always crank/camshaft. If I try to start it right after it dies I’ll get long crank no start Sometimes it’s long crank barely start and run like crap I’ve chased wires. Checked connections dielectric grease on stuff I’m not getting these hard shifts or anything like anyone else it almost makes it immobile I’ve had a few different places try to scan it or hook computer up and everyone only ever tells me crank/camshaft code

 

Bud hasn't been here in a decade.

Post your codes and vehicle info please (engine/miles), ideally in a new thread. Thanks.

 

I know this is not going to make any sense but if you're truck has displacement on demand and you have low oil pressure or any type of misfire which is very common with these trucks any type of problem with this system with cause you're issues as I have a 07 chevy Tahoe with the exact same issue

 

My 2008 Chevy Silverado 1500 is doing the same thing. Only difference is I can turn on the air conditioner and that will cause the traction control and stabilitrack lights to come on. Sometimes they come on on their own without the air conditioner being on. Either way I've had some aftermarket parts put on this truck over the course of the last 2 years. I have no idea what happened before that as I purchased this pre-owned at a Chevrolet dealership. The warning lights are coming on intermittently. And it shifts really hard when the lights are on but yet when the lights go off it shifts normally. It acts as if it needs another coil pack but I have replaced the same coil pack three different times and the spark plug as well I've also replaced the plug wires I have went as far to purchase O2 sensors and have cleaned the fuel injectors. I'm at a loss here don't know what to do can you please help me?

I don't have a TCS button to press. How do I turn it off?

 

try checking your wheel speed sensor.

 

for a button?

 

I was getting those lights on my 2015 traverse and when I replaced the brake pedal return spring, it seemed to correct that problem. Before I changed it, I verified by holding my toe underneath the pedal to keep it all the way up and the lights did not come on until I removed my toe.

 

Hi
just a note:
I had the stabilitrac light coming on for years and no one could figure it out. I finally noticed that my motor mounts were broken. Fixed them and no more stabilitrac light. Been fine for several years now.
To check the motor mounts, have a driver put on the emergency brake, put their foot on the brake and put the vehicle in reverse. Give a little gas while holding down the brake. If the motor lifts up
the motor mounts are bad. Good luck.
