Heatilator gnrc33

Hi, we have a Heatilator gas fireplace that won't fire when we flip the wall switch. It has a pilot that I cannot get to light either when I try to relite using the instructions in the control box, was working last year then went out by itself and the pilot went out to. Is it a Wall switch problem or control box problem, can it be diagnosed by me dont really have the 269.00 for a service call here
Thanks

Remove the plate & the wall switch from the box. Remove the two wires from the switch & touch them together. If the unit lights, it's the switch. Replace it. If it doesn't you have to look elsewhere...Let us know how you make out & we'll take it from there.

Removed switch and by passed or hooked the two wire together. Still no light and I do have spark from piezoelectric lighter

Ok. Do you have gas on? I knob in PILOT position?

Yes, held pilot in with red knob on, pushed lighter 5_10 times, spark but no light of pilot

Take the front glass off & remove the logs - remembering their placement.
Stick your head in the firebox when you depress the PILOT knob.
*** DO NOT HIT THE IGNITER ***
Do you hear a hissing sound? If you do, keep doing this until you smell the fuel.
Get your face outta there & THEN hit the igniter.
Lemme know how you make out.

Yes to both

I'll try disassembly and is there anything I can clean? Nozzle ext?

Make sure your peizo igniter isn't grounding out to somewhere else.
You want ALL the spark to hit the gas flow at the pilot hood.
