After being outside all winter my Weber Q grill has very low gas pressure, barely enough to stay alight, not enough to cook on. I have attached a fresh propane cylinder, but that makes no difference. Might a nozzle or tube be blocked? If so, how do a clear it? Will buying a new part help?

You problem could be or probably is with the regulator...not enough gas
Well it coulbe caused by these newer type propane tanks with the anti tip safety device installed inside them. To rectify you simply remove the tank to clear the pressure in the line and open all valve son the grill. Then close all valves on the grill and reconnect the tank. Then open the valve only just enough to allow gas into the grill, just crack it open a hair. Retry.
This could be caused by a couple of problems. First the regulator could be bad, or the tank is getting to hot. Which causes the relief valve to open and release pressure. This will happen when weather outside is hot.
There could be several things causing this problem. First, the burners need to be checked to see if they are stopped up. Grease and oils from grilling can clog them. Also incects like to make cosey homes in them over the winter months. Lastly, this problem could be the gas regulator going bad. Good luck!
Hi Lyon, Yeah, it's the regulator. Fortunately, they're cheap and easy to replace!
You can look on line for part number 80012. Or you can remove yours and take it to Home Depot or Lowe's in the outdoor cooking area and match up a replacement. <--- they're all the same... just make sure the compression fitting (the brass end) is the same size.
The only other thing I could recommend is this... Turn the LP bottle completely off. Then completely remove the big plastic knurled knob from the tank. Now replace the knob back onto the tank (all the way and make sure it's tight). Then S L O W L Y turn the gas back on. Now try your pit. If you get the same flame, it's the regulator. If you get full flame, you just reset the safety device inside the tank.
I'm betting regulator. Good luck and happy cookin'!
I just experienced the same exact problem ! I just bought a brand new Weber E-310 a 3 burner grill.
After I seasoned it up with cooking oil,I turned all the burners to high, opened the tank and clicked electrnic button several times , the grill was on then I went inside, I came out about an half-hour later and it was saying around 275 degrees..
I looked into my manual and there is a gas limit control valve that shuts down gas flow, when it thinks there is too much gas flow.
Turn the propane gas knob to off
Turn the gas grill knobs to Off.
Click the igniter several times to clear out any gas.
Then unscrew the regulator from the tank,( I then blew into the tank hole and regulator),
Screw back on the regulator to the propane tank.
I then clicked igniter again couple of times.
Now open your propane tank.
Then turn on front burner while clicking igniter, this will lite 1st burner.
Then turn 2nd burner on low then to high.
And if you have 3rd burner or more, turn low then to high!
John I did this and my grill went to 600 plus in a few minutes!!
The problem was turning the gas grill knobs on first then opening the tank then lighting...
You have to open propane tank with knobs off, THEN AS SOON AS YOU TURN ON 1ST KNOB, YOU MUST IGNITE ...
