You don't say how many DUIs you have had or what the suspension is. If you have not paid the reinstatement fee to the Bureau of Motor Vehicles or provided proof of insurance, the suspension will continue indefinitely. A starting point would be to check the BMV website and see what the suspension is and what you have to do to clear it.
A suspension is different than a revocation. It will end at a certain time so long as you do everything you were required to do including paying any reinstatement fee.
