2500 clay

Posted October 22, 2019

I have a 2012 gmc Sierra 2500hd that won't start if the tank goes below an 1/8. Also sometimes the pump doesn't stop running when I turn the key off. Any ideas would be a big help. Thanks.

  I just finished my first mow of the year. That Camaro headliner job sounds like a solid weekend project.

  I am sure the Dorman pan will be just fine, should hopefully slip in just like the factory pan without surprises although I've never actually talked to anyone that has installed one so I am just assuming it should fit, you will soon find out. Like I said I honestly figured these companies would poo poo the gas engine for aftermarket parts for the transmission pan wise simply because the meat and potatoes market is the Duramax due to them being the trucks that more often then not would be asked to tow really heavy weights and be looking for more oil capacity and cooling. I never happened to hear any words one way or the other by any company including PPE as per a plan to build a L8T version of the trans pan and so was surprised when I came across that the other day. I assume the pan you bought cost less anyway as these specialty companies like PPE, Banks etc sure don't give their products away.

  So, you're not a fan of doing electrical testing?
- 2023 GMC Canyon Elevation with 55K miles. Having trouble with Front and Back door actuators. I have replaced the driver side door and passenger back door actuators already. Now I'm having a problem with the driver side door again.

  have you considered it's an electrical problem, that you just temporarily fixed by moving the wiring and/or cleaning off the connector by disconnecting/connecting it?

  you might wish to use the right bolts, and may need to replace the nuts, if you prefer the seat stays in place in the event of a collision.
