Too much gas pressure. It is made for small disposable tanks only. FUEL TYPE LIQUID PROPANE (DISPOSABLE CYLINDER SOLD SEPARATELY) https://www.weber.com/CA/en/grills/gas-barbecues/q-series/50060001.html ..

Try lighting it with a fireplace lighter or long match. If it lights, your problem is your igniter. Either keep using lighters or replace the igniter.

Try reaming out the holes that aren't lighting with a nail.

Are you using the valve-regulator or a conversion hose to a 20lb cylinder? a gas problem is different from an ignition problem. If an ignition issue the piezo module on that model has to have a good ground connection because cast aluminum will not ground at the electrode. make sure wires are tight and secure. Also check the "gap" at the tip of the electrode and adjust for strong blue spark. Most barbecues need the electrode gap adjusted when first installed. if an older model dirt and grease will interrupt the spark so make sure the tip of the electrode and area around it is clean -- burner and collector.

try cleaning the burner and the orffice first

reg could be stuck down on seating or blockage in gas line , turn off gas remove line open burners , close burners reconnect gasline turn gas back on slowly see if this works .

check burners are not blocked, also air gas mix could be wrong you should be able to adjust the mix on the burner , and see if burner is not split this can also cause flash back .

Contact Weber. They have good customer service. A regulator should last "forever".

You need an extra set of hands for the ignition assembly. The gas leak is probably in the tank connection assembly. The plastic fitting may be cracked. Unfortunately, you're the third person I have had in 5 days, that has had a leak in their Weber Q100. The last time I checked for someone, the gas tank fitting/holder was out of stock. No available date was listed. You may want to convert it to take a 20 Lb LPG Grill tank. Ironically, that conversion part is available.

Hope this helped you with the leaking situation and I wasn't kidding about an extra set of hands.
