My cars having a starter issue,i have to press on rhe gas and turn on the key

Is there any way i can check myself to make sure? When i turn it on i hear it come on but the humming stops a couple seconds later. Is it suppose to stay humming ?

It will run for around 3 seconds if you just turn the key to run and not start your engine. That is to prime the fuel system before starting the engine. If yours takes longer after sitting overnight, try to cycle the key from off to run several times before starting the engine, it will start sooner without cranking the engine forever before it starts. You are probably acting like it's a carbureted engine, trying to pump the gas as the older cars with carburetors had to be done. If the fuel pressure is there, then it will start.

Ok that sounds like i would try that but what is the tps ?

Throttle Possition Sensor, as stated mechanic will know!
