Not firing on left cylinders??

Hey.

A mate got me to take a look at her 93 WRX which started running rough.

Checked it over and found it not to be firing on the left two cylinders, no spark coming from either coil pack.

Has engine check light on and code reads 45 which as far as i can see is MAF sensor but i cant see how this can relate to the problem.

I believe its not the coil packs that have failed as it would be very unlikely for two to fail at same time and they generaly break down under load rather than stopping all together so can assume its what controls the coil packs, maybe ecu?

Has anyone has this problem or no whats causing it?

Thanks

Nic

I havnt checked power to the coils as didnt have a multi meter or test light, my guess is that it doesnt, i will check when i can tho - if it doesnt what could be the cause of it?

      Afternoon team,
      im new to the group first time posting. Im hoping some body can help me get my launch control all dialled in on my link g4x. Ive had the computer and car all tuned from chris at prestige awesome knowlegable guy super happy with the results but now im wanting to get my launch/anti lag all dialled in. Ive been reading multiple different forums etc all with different conflicking information which has made me nervious with what do i listen to this or that if you get what i mean. Now ive started to make myself familiar with my PClink software etc the past few weeks and im eager to learn how to do minor setups or tweaks etc so im not relieing on my tuner so much and obviously saving myself abit hurt in the back pocket. 
      Now back to the question at hand.... Im wondering if theres and one who could please share there knowledge and wisdom with setting all my values, timing, fuel etc when i have launch control armed and engaged, or even a launch tune file they can possibly send me to load onto my tune. Ive figured out the setup of my digital inputs turning launch control on etc and its obvisously on its pre set factory settings. It engages but doesnt sound the greatest or as angry as it should i feel. Hence reaching out to you good buggers. 
       
      Cheers in advance for any info and help yous maybe able to give me.
       
      Cheers Shaun
