All of that can't be fine. That's all it takes for the engine to run.

Are you sure you tested them correctly? Is the engine cranking at all or do you just get a click when turning key?

Since that problem ocured the engine light came on and we scanned it and it say evaporative emission system pressure sensor/switch low. Could you please tell me what that means, now when I start the car I have to use the gas pedal to help start the car besides it runs well it also has a slight miss in it and a rich smell thank you for your help

DTC P0452 : Fuel Tank Pressure Sensor Circuit - Low Voltage

most likely cause of this code is a faulty fuel tank pressure sensor, but you will also want to test the wiring to the sensor first. The sensor should be located under the rear of the vehicle, in tank on fuel pump assembly.
