Inherited this grill from my neighbor. When I got it, there was only a super low flame first time I turned it on. Second time, no flame. So I got a new regulator.
I’ve watched dozens of videos about how to secure a new regulator and get gas through but im having now luck. With the new regulator, I briefly had a super low flame. Now, no flame/no gas pulling through.
Any ideas? This thing is driving me crazy. Have spent hours on multiple occasions trying to solve. Thank you!!

Have you tried a second propane tank? I’ve gotten plenty of shitty cylinders that have low flow and had to exchange them.
Is the hose new, might be clogged up with critters webs/nest. Also check the burners to make sure nothing is clogged up.
Remove the burner tubes and check that they are not gunked up or similar.
If they are okay and your new regulator is not faulty then your manifold is most likely fucked though I’ve only seen that once in almost 10 years of selling Weber.
Was salt buildup from living right by the sea.
In addition to what was said, make sure you have the gas off, and burner controls off. First, turn on gas, then turn on burners and try to light.
If you turn on the tank valve with the burner controls on, it will shut down the gas, because it senses the lack of pressure against the closed burner controls, and treats it as if it were a leak.
One thing to try is to make sure the grill burners are completely off before you open the valve on the tank. Sometimes when I don’t do that I get a slow draw
just to make sure, you’ve turned off the gas then slowly turned it back on? I recently learned that turning on the tank too fast causes low gas flow. not sure if it can cause no flow though.
Your neighbor obviously couldn’t figure it out either. Rather than dump time and money into it, he just bought a new grill.
If I had to guess the problem, I would guess that there are spider webs in the burner tubes,
Sometimes, it’s as simple as a clogged burner or the regulator tripping the safety. Try a full reset, disconnect, wait, reconnect slowly, then test with soapy water for leaks.
There is a safety feature on most propane tanks. When you turn on the grill before you open the the tank. It caused the check valve on the tank side to close. Unhook all lines and turn the propane take completely on, then close it. Connect the hose to the tank again and to the grill. Turn the tank on all the way before you even touch the grill. Hopefully it’ll reset the check on the tank side hose.
Try rotating that regulator near the tank so it is horizontal. Had this issue in the past and someone told me this exact thing which seemed to fix it. Apparently, The regulator will collect moisture and if it’s not sitting correctly, it will prevent the propane from traveling at full pressure, or entirely
Yup when you are getting little flame just turn the tank off. Unhooked the hose from the tank and lightly bang the hose on the tank. Sometimes the valve gets stuck partly open
If this grill has a side burner, make sure it is all the way off and there isn’t any flow of gas. I have seen situations where the side burner was slightly on and prevented the other valves from fully opening on the main burners.
Looks like a Weber that needs a regulator reset

I just had the same problem. Ended up needing to replace the regulator.
When you turn the tank on, turn it on very slowly for the first few turns. That should do the trick .
OPD.
It’s definitely dirty, this may not be why it’s not functioning, but with the amount of fires people have because of this you should really clean it. Even if you don’t have a fire it will make your food taste bad. Critters get in there too.
Idk if it’s just the angle of the image, but that gas line /t the top looks pretty bent, could it be restricting some of the flow?
I had this experience before I flipped the gas tank upside down and flowed much better as last resort I changed all hoses and a new tank
Probably OPD on tank.
Turn off grill and tank.
Remove regulator from tank.
Screw regulator hand tight on tank. Pick up tank and shake it around gently. Tap bottom on ground gently. This will help reset stuck OPD or excess flow valves.
Open tank valve slowly.
Open one burner to HI and ignite. Flame should look normal.
If not, replace tank.
If new tank still does it, chances are you have a leak in the grill before the burner valves, thus causing gas to escape engaging the excess flow restriction on the tank.
Check for leaks in the gas line system on the grill with soap water.
Tap on the regulator with a tool like a pliers or a screwdriver handle!
Have you tried slamming the lid down a few times? That usually works for me
Use a charcoal grill.
Ain’t got no gas in it
Get a charcoal grill.
If you’ve tried the sequence and unclogging suggestions, then maybe try a A/B swap with a neighbor with a working setup. Try your tank in his setup and his in yours.
The end you screw on pushes a spring loaded check valve in so that gas can flow through. There is an o ring in them to help them seal when the o ring is new it makes it so that the part you are screwing in gets tight before it’s fully depressed the check valve. If the o ring looks new and is still round tighten it extra tight and it will work…
If the tank was over-filled, liquid could be getting into the regulator and freezing it.
But it’s most likely the safety valve shutting you down.
Sometimes the OPD valve (triangle handle on tank) trips and you have to reset it using the plastic end of a pen or screw driver. See video below. Beware propane is cold and can freeze your skin even with gloves on.
