Carrier Weathermaker SX won't ignite pilot

I am having issues troubleshooting my Carrier Weathermaker SX, model #58SXA060-GG Series 100. About 60% of the time when my thermostat calls for heat I don't get any spark to my pilot. When it does NOT light, my inducer motor will start and run, I hear a click that comes from my HSC ignitor/lockout control (part number: LH33WZ513A), then I loose my 24v to my pressure switch and it will eventually shut everything off. I have checked both of my intake and exhaust pipes for debris, they are clean. I have checked all of the drain tubing and cleaned out the drain trap, it is clean. While the inducer motor is running, I can ohm the pressure switch to make sure it is closing and it does. It stays closed, even after I hear the click from the ILO, it is still closed. So far what I know, is that when my thermostat calls for heat, I have 24v coming from "W" to my ILO going into pin 5, then when my pilot does NOT light I hear a click and loose 24v at pin 1 of my ILO. I am guessing I am hearing my 5-minute lockout timer open when that is happening. I believe that my ILO is failing, but because I am not a HVAC tech, I would love a second opinion on this matter, and have someone tell me if there is something down stream, maybe a faulty ground or connection some place else that could be causing my ILO to open and not produce a spark. I also know that if I jump 24v to the c terminal of the pressure switch, basically bypassing the the 5-minute lockout, my pilot will light, my main gas valve will open and my main burner will light, at that point I can take my jumper wire off of the "C" terminal of the pressure switch and the furnace will run until my desired temp. Any information on this would be much appreciated.
