You probably have an air bubble and therefore doesn't have enough anti freeze in the system. Carefully remove the radiator cap when the engine is running and verify it and/or notice the hot/cold marking on the overflow tank. The system needs to be full to heat.
It may be the linkage between the shifter and the transmission. It has plastic bushings and sometimes they crack and it just doesn't shift in an out of park right
The instrument cluster in these GM vehicles have stepper motors that control the gauges. It probably is the stepper motor for the fuel gauge going bad. This should have nothing to do with your hesitation, which could be anything from an O2 sensor to a good tune up.
Gidget,, please do not "hot wire" this vehicle.. if you lost your keys.. go to the dealer or call a locksmith,, you will have more issues later if you hot wire it...
Hi. Every car this days have immobilizer and key or phobe coded to it. If you replaced key but didnt switch guts to new same case you won't start up the car and you will have security codes pop. Usually service does such things. I don't think you guys can do it without equipment.
I would not think starter , maybe park neutral switch > It's a safety switch that won't let the vehicle start if in gear . If it doesn't start again try an put in into neutral an see if it starts . But to make sure starter is not bad do a starter circuit voltage drop test . Starter Voltage Drop
What grinds ? the starter ? if so it's not a key / ignition area problem . If the starter didn't do anything it could be a key / ignition switch problem . It's sounds like you really should take your vehicle to a qualified repair shop .
It is part of the O2 sensor. Sensor two is the sensor located behind the catalytic converter in the cylinder bank that doesn't contain the #1 cylinder unless it is a 4 cylinder engine.
