I assume the grill is configured for natural gas (propane generally requires a different pilot orifice unless the owner's manual states otherwise; they are not interchangeable). The following is written as a generic explanation; see your owner's manual for a diagram of the internal gas piping. If you need further assistance, please ask in the comment box. If you do not have a sediment trap in the gas piping, the pilot tubes may be clogged with white sediment similar to the lime from tap water. In this case, you will not be able to smell any gas at the pilot outlet. The clog is usually right at one or both ends of the tube, inside the fitting. It is important to get both ends properly tightened after repairs. The end connected to the supply obviously needs to be tight for safety, and the flame end needs to be tight to maintain proper pressure for the flame. Test with soapy water; there should be no bubbling when it is applied to the connection.

May be you need to replace the igniter. The igniter is easy to break if it is used for a long time or if it is not used for a long time. My grill also replaced the igniter and the burners in June, they are all rusted, i bought them at this online store and the quality is pretty good grillpartsreplacement.com/collections/kitchen-aid-720-0745b-gas-grill-replacement-parts-and-accessories
