First thing can you hear and smell propane running. If you can then try and start with a match. If this works your ignitor is probably dirty in the grill area. Where wire connects under grill look at the metal that this is connected to, could be dirty with grease or just needs to be bent closer to metal that it sparks off of. If this doesn't work then ignitor button is bad and needs to be replaced. You can buy at lowes or home depot.
