temp gauge bottoms out to cold side (non working), when i turn it off it is very hard to start

injectors but that would not cause problem with temp gauge.

Why guess what is wrong with your car when you can scan the car for the stored fault codes? How do I know there are codes? By the glowing Check engine light. Those bulbs are int eh dash for a reason. Go to your local auto parts store and ask them to scan your car, they usually do it for free. Post the 4 digit code back here and we'll get you on the right path. ex. P0171

Could be a problem with the coolant temperature sensor or wiring. The temperature sensor is one of the sensors in the car that determines how much fuel is delivered to the engine, depending on the temperature of the engine. There is a difference in how much fuel is delivered depending on how cold or hot the engine is. If the temp sensor reads cold when the engine is hot, the computer will send the wrong amount of fuel to the engine, causing rough idle concerns and sometimes a hard start scenario. This may or may not be the cause of your problem, but it's a good starting point. I agree with Tom, get the code checked out. If you find yourself in a situation where you're over your head, visit a mechanic and get a diagnostic performed on the car.
