Fuel pressure question with racetronix pump
Hello i just recently installed a racetronix fuel pump,hot wire kit, Fast fuel rails and injectors with gauge mounted to fuel rail. i notice that when i turn the car off the pressure gradually falls to zero from which i understand is normal i guess. the thing is say after the car has been sitting for a while and i go back out and pop the hood the pressure will be back up to like 30 or 20 lbs and then gradually drop i have even had the hood up and the gauge reading zero all of a sudden it will spike up to 30 lbs so could the pump be getting little power spikes or could it be a relay? all of this is happening with the car off key not even in the ignition. car starts up fine and holds a consistent 65 lbs at idle any thoughts are appreciated
