Hello Anniesattic0,
Well it sounds like you're describing at least 4 different issues:
When i would start the car there was a scraping sound
This could be a multitude of issues. Bad starter, electric cooling fan attempting to turn, water pump failure, insufficient engine oil, etc.
i would have to drive faster to keep the temp down:
Never a good idea. Sounds like water pump has failed, or electric cooling fan has failed. Lack of coolant (NOT water). Thermostat stuck open.
when i get to a light it would idle and feel like it was wanting to die.
Probably overheating due to afore mentioned cooling fan or water pump issues. Possibly IAC (Idle Air Control) valve failure, EGR valve failure, MAF/MAP dirty, TPS sensor bad. I would lean towards IAC Valve failure or port blockage and/or engine temperature issues.
I went to start the car and when i turned the key it would want to start but wont.
Is this when the engine is hot? Again due to the first two issues.
If when cool, then check the entire charging system (Battery, cables, starter and alternator. Ensure all cables are in perfect shape and connected well.
Based on your description, I would lean strongly towards Water pump failure first. Electric radiator cooling fan a close second. Then have charging system checked.
It's time to find a good mechanic to help you out.
Best regards,
