Hello I have a Bryant gas furnace the model # is 383kav042091. The system will go through 4 cycles, but it will not lite. The led code is 34, I have cleaned the flame sensor as well as the part that lites up. Can anyone help!

I hope you did not clean the part that lites up. They are sensitive if it is a HSI system. They do not like fingers to touch them.

This one has wiring diagrams and troubleshoot section.

Now you are armed and dangerous. LOL

I believe it is the HSI ignitor or no voltage from the board for the ignitor.
Now get to work it has to be cold in there.

I pushed in the safe guard switch but nothing happen. Is there away I can check the voltage from the board to the ignitor?

Sure is just removet the ignitor plug from the board and see if 115 volts or there about is present at the terminals. Easy does it becareful not to touch your probes together. You can also test the ignitor with the OHM section of your meter.

I have cleaned the flame sensor aswell as the part that lites up. can anyone help!
I read that part and cringed lol.
