No it's not right. First step is diagnostics as many things can stop it rising. If the pump failed the EAS may have logged a hard fault, do you have the slow 35mph message on the dash? If you do, the compressor will not run until the fault codes are cleared.
Pump failure is often due to leaking air bags, how did you check them?

yes had them checked no error messages took them off and presure tested each one no leeks it will only pump a bit of air in and not stop flashing on dash

how do i clear codes were can i get soft wear? its a brand new pump

So the pump actually runs? Are all 4 lights flashing on the EAS switch unit?

yes but does not rize to ride bottom and ride hight keep flashing

Where are you located ? Someone may be near & might help.

So if the pump runs but it does not rise, either there is a leak or the pump is not making pressure.
with the engine running, leave a door open and check the pump is running, remove the little silencer at the windscreen end of the valve block and check for air escaping. If that is OK, wait 7 or 8 minutes then shut the door and see if the car tries to rise.
You cannot really check the airbags for leaks off the car as you cannot pressurise them enough without destroying them.

thank you

Also read the EAS thread in the Technical Archive at top of this forum. Download the EAS System Info Document.

Lots of details in both about how the system works & how to diagnose & fix the faults.
