Hi All, First post on the forum here so let me know if more info is needed. Was recently putting a new set of headers on the truck and decided that at 200k+ miles, I should replace the starter. My hope was to avoid having to pull the headers when it did eventually go out. I purchased a reman of the OEM part (GM Genuine Parts 323-1637 Starter, Remanufactured). Part went in no problem and I also replaced the heavy gauge wire to the battery as well as the smaller gauge wire to the ignition switch. All was functional for the first week or two, when I turned it over and got nothing... No clicks, but the battery had power, dash lights looked good. I hooked a power pack up and it started no problem. Thought it was a fluke or I left a light on, but after having a no-crank condition maybe one out of 15 times that I start it, there is definitely something going on. Here's the weird part... every time that it does not start, I eventually get it to start with no changed conditions. I've tried starting it in neutral which worked the first time, didn't work the second. Another time I screwed with the battery terminals and it started, one other time I just sat there for a minute or two after no-crank and it started. Battery tested fine but havent taken a multi-tester down because it's been starting anytime I am home. Any ideas?
Help with 06 Sierra 6.0 liter gas, Getting a P0430 code on my "Ancel AD410" code reader, and No OBD2 scanner reading for short term fuel trim bank2/2 just _ _ _ I tested before Cat and after Cat temps on bank 2 with only a +30 degree f. diff at second O2 sensor. Where or what do I check to find the problem with the "short term fuel trim bank2/2" and is that why I get the P0430 code?
