We started the car and it didnt want to get off idle so we taped on the air filter and it started to eccelerate we were told to clean the mass air flow censer and we did and now the car wont start we had lost power first and someone said to do a tune up on it the car has gas in it and we were told to check the fuel pressure how would we do that
You would need a fuel pressure gauge and the attachments to hook it into the fuel line before the injectors.
You can spray carb cleaner into the throttle body to imitate the injectors, just don't spray it thru the mass air flow meter.
Its possible the mass air flow meter was failing and your cleaning it finished the job. They are very precise components. There could be an air leak between the throttle body and the MAF meter.
You could need a simple fuel filter too.
If it will start on carb cleaner and the filter is good, you may have to get a book to troubleshoot the mass air flow meter.

your fuel pump should cycle on until the proper fuel pressure is achieved then it should shut off

Probably a good idea to change filter. Gas in oil due to attempted starts and flooding. Additives will draw out water and make white smoke. Been there, seen it. New gasahol will separate within 6 months and will draw and accumulate moisture like diesel. Since no default lights are on you could still try autoparts store like Autozone or similar and ask for test but without faults probably a no show. The additives could cause high idle until you are burning 100% gas. Check to see if all vacuum lines are correct after removing air filter.

Take off cap and see if rotor turns when you crank it. If electric fuel pump see if inertia switch is tripped from closing trunklid or doors.

Ignition system sounds probable on vhicle when everything gets warmed up. High pitched hum could be bad tire or worse bearing.
Testimonial: "Thank You for your response. The huming sound is present on idle from start-up,tires have just been replaced, would fuel pump be suspect?"
