when it was working after reset the pump works well and lifts and lowers car as it should if I had a bad leak im guessing the pump would want to work all the time to keep the pressure and the car would go down over night which it doesn't do it stays up like I have said the pump sound good not noisy and the system works well when it wants to after a reset. the diagnostic tool was a "Snap-On" one.Has all faults been reset and cleared with suitable tool?
Remember to check for faults again after reset.
What tool is used?
Sounds like its telling you the pressure in tank is static ie bad leak or faulty pump.
