February 10, 20188 yr Hello- I have a 1998 forrester with an unknowned year 2.2 engine (it's a frankencar). I've had this car for almost ten years and it has ran good untill now. The problem is a no spark issue. I have changed the crank position sensor and coil and am thinking about the icm. Searching online I found a vendor that listed two for my engine, both looked like they would plug in and work. One cost $30 and the other was $160. I was just wondering what the differance is between them? Thanks, Red. BTW, the car runs good it's just hard to start at times.
February 10, 20188 yr I suggest you check the Coolant Temp Sensor. Hard start intermittently is often this. ICM or "Ignition Transistor" seldom fail. And if they do, it's usually a hard fail, not intermittent.
February 10, 20188 yr Author thanks for the reply Gloyale, I have replaced the coolant temp sensor. would the cam position sensor be worth a try to replace? Thanks
February 11, 20188 yr Author the plugs are NGK, the wires are a napa brand. In a no start condition, I use a good NGK plug and pull a plug wire off and make sure the plug threads are grounded. Eventually the plug will start sparking and sometimes the engine will start on three cylinders. Sometimes when this happens, the spark looks weak (orange). The car has never left me stranded, just once a week is hard to start. It has never been hard to start cold. I just thought I would try a ICM for $30, if I need the $160 ICM, I'll have to think that over. Thanks for your thoughts, Red.
February 11, 20188 yr I may be wrong on this,but I put dielectric grease on my boot connections,maybe some else will chime in here.
February 11, 20188 yr get some better wires - NGK wires or OEM I have used the parts store brand of wires before and had issues with them, as have others. They just don't last
February 12, 20188 yr Author subaru plug wires are supposed to be here by friday, thanks again for your thoughts, red
