No pressure on furnace gauge

[Nstep71]

Have no pressure reading on my gauge. Do however have good water temp. Also can hear hot water coming into radiators when heat is called for. What could be the problem??

Please help!

With pump and boiler off is there pressure? Take some pics of the boiler, piping and expansion tank

Thanks for everything. Actually was a broken split section of pipe in a out of the way feed line. Repaired the split section of pipe and the pressure began to build again. Must have frozen during the deep freeze night we had recently. And thawed this morning.

Might be a good idea to install an aquastat with a low water cut-off. Running a boiler with low water is a good way to kill one.
