Hello I will help.

This is a 2002 forester with the 2.5L engine?

The crank sensor is on top of the crankshaft pulley in the center front of the engine. The cam sensor is to the driver's side of that on top of the cam sprocket on the front of the enigne.

I will get you a diagram of the location if you can confirm the year and engine size.

2002 forester. 2.5 engine. What other issues could this be.
Expert:  George H. replied 9 months ago.

Good, click here for location

Other issues could be a failed computer or the belt has slipped.

How long since the belt was replaced and was the tensioner replaced at the same time?

Customer: replied 9 months ago.
30k miles ago and I'm not sure on the tensioner. I'm hoping it isn't the ecm but this thing just quit on the on ramp of the interstate.
Expert:  George H. replied 9 months ago.

OK, without spark then I would replace the crank and cam sensors, they are less than $50 for the pair.

You should check the belt timing as well to see if everything lines up. Not knowing about the tensioner you may have skipped some teeth.

let me know how I can help

Both sensors? I did purchase a cam sensor and coil pack which is going vack. Lol I never installed it just connected the wires and put an alligator clip to ground to be sure. So next question I guess is how hard are they to replace. Just had back surgery and can't crawl around too much.
Expert:  George H. replied 9 months ago.

Pull out the 10mm bolt and wiggle the sensor out of the bore. You will have to bend over the top of the engine bay but nothing underneath. Everything is on top here.

If somone use the coil pack as a hand rest then I would not send it back. That can kill a coil
