Question about 2000 GMC Sierra
If your starter has 2 or more small wires on it you may have switched the terminals. If you have a separate starter relay you can bypass the relay with a jumper cable and send 12 volts to the starters only main cable. It should crank, have it in Park (Auto) or Neutral (stick shift). If the starter does not crank bypassed then the only thing missing is a good ground. Use a pair of jumper cables and try grounding the starter case and connect the cable to a good ground. With the gauges dancing usually a bad ground is the reason, so the jumper cables will help with that problem too, at least for test reasons.
If you had the old starter tested, then you know it was the first problem. But if the old starter was not tested your problem could be a bad starter relay, an ignition switch,or finally a bad ground. Check the grounding of the remote starter relay, check for a plug-in connector off the end of the steering column for corrosion.
