I am having issues with my 2009 GMC Sierra. It has around 330,000 kms.

- Service stabilitrak pops up constantly and sometimes says stabilitrak is now off.

- 3 cylinders are not firing

- Engine lights keeps blinking

Is there something simple that could be causing these problems like a bad fuel pump? Spark plugs? Or is it time to find a new truck?

I replaced spark plugs not to long ago so id think those should be good?

Any comments would be helpful.
