Default 98 forester no spark on front cylinders

Ok I have already tried to change the plugs coil and wires . Checked all plugs and connections . I have not tried a new igniter . They are like 6
250 and impossible to find used . I was also told that if I have any power coming out of the igniter it most likely isn't bad . I was given this car and it has 195 k on it so I dont want to go crazy with it . But that igniter and computer are the only thing left I think . Any way to check these things . I have also checked the magnets on the cog wheel and the things under the crank sensor . Any help would be appreciated .

How did you determine no spark? Can you swap parts to other cylinders like injectors? Any DTC or cel? What engine is in it? Is anything on the ignition system isolated from front cylinders to back cylinders?

Any DTC or CEL? Sounds like getting your hands on a known good ignitor might be an easy way to find out

I'm having exactly the same problem on my forester S 98. Changed the ignition coil and no spark at cylinder 1 & 2. Changed the ignitor and still no spark. No codes whatsoever. Next in line is the ECU, I pulled it out and I'm going to test the wires for the ignition control of cylinder 1&2 see what happens.

I'm pretty convinced it has something to do with the ECU. I heard the pre-cat O2 sensor could also be at cause.

Keep me updated if you find the cause thanks.

I've got a 97 Brigton w/1.8 electronics/wiring and 2.2 long block and I've been dealing with the same issues, good spark on the front two cyls but not rears at the coil. I've replaced plugs, coil, ignitor, cam and crank sensors, and still have no control voltage on the top wire at the ignitor. I'm down to just being the ecu issues.
I just picked up another 97 OBS but its a 2.2w/egr auto so I'm not sure if it can swap.
