Why is my pressure canner not building pressure?
You must have it fit properly on the lid, or it won't build pressure in the container. With the steam escaping, your pressure cooker won't build the pressure it needs to cook the food. In some cases, a blocked float valve happens as food gets stuck near the top of the lid and blocks it off.
Why does my pressure cooker take so long to build pressure?
If your pressure cooker tends to take a long time to pressurize, this is likely due to you overfilling it. A pressure cooker will often take a long time to gain pressure the more food or liquid you put inside of it, and you could even have trouble keeping pressure while it's on.
How long does it take a pressure canner to start streaming?
6. Once the pressure vent starts releasing steam, set your timer for 10 minutes. Allow the canner to “exhaust” for a full 10 minutes before you do anything else. You'll know when the steam starts to escape, because it will begin to sputter and hiss and usually some water droplets will appear on the outside.
How long does it take for a pressure cooker to reach 15 psi?

Can siphoning occur at any stage of processing?
And as we all know siphoning can occur at any stage of processing, not just at the beginning and has other causes besides any "initial overshoot."
Can you can on a coil stove?
I agree with Dave. You may have a dried out gasket, there shouldn't be that much escaping steam OR water loss in your canner. Before we moved, I did can on an electric coil stove with no problems, but I definitely shortened the 'come to pressure' timing (which was no where close to an hour to begin with!) by buying a heavy duty canning burner. Easily interchangeable on the stove I then had, and it worked great for things like stir fry too.
