    I would check the computer for trouble codes anyway. Could be several things like a leaking EGR valve and so on.

SOURCE: 1999 Gmc Sierra has no power

Sounds like the fuel supply is inadequate. Check for a plugged fuel filter, or possibly the fuel pump is losing pressure. I had a 93 Chevy V6 that acted the same way, and after checking everything else I replaced the fuel pump, which solved the problem.

SOURCE: 99 gmc sierra... seems like the abs is taking over

It sounds like it's the ABS module has gone bad, your going to have to take it to the dealer and have them service it. There are special tools that the average person don't have in there tool box. You can go to Auto Zone and see if there are any DTC codes, but if there are no light on the dash. It may not show any and the dealer will have to test the module. Good luck and hope this helps. keep me posted, be glad to help.

After sitting in garage unused for 2 weeks 2008 gmc sierra 2wd starts fine, but ABS light stays on, in D clunks into gear then check engine light came on. 18000 miles. had no issues when parked


That is really low mileage for issues but clunking into gear is a symptom of a bad universal joint on your drive shaft. Does it clunk in D and R?

put a remote starter cycloid on the firewall that's hooked to the one on the starter to get rid of the having for it to cool in order start it. At least that solved my problem. As for the brake light flashing..well mine does too but everything works....it's most likely a short somewhere. The biggest problem is driving off with the parking brake set. As for the hood. My paint is fried as well. I think it's because there is no insulation installed under the hood. Who knows. Good luck
