I have a 98 subaru legacy b4. She has a ej208 engine. We just put a new ej20 block in her and we only have spark on cylinder 1. We have power to the other 3 coils but no spark. Any ideas?

And thank you for adding me. Not sure if its the right spot. But we have been stuck on this issue for days really could use some advice 

Others here will respond I'm sure, I'm just wondering if this could be an issue with using the correct crank sprocket. It may matter to the ECU how many 'tabs' are on the sprocket for the CPS to detect.

I will check that out and let ya know ...thanks for the input 

So I replaced the crank gear as you were correct it was different. But it won't start. Do you think the cam gear would be affecting it as well? Or might there be something else?

yeah, the ECU in the car needs w'ever crank/cam signals it is expecting so, possible cam gear differences too.

Ok thanks again will update you 

One other question, the cam and crank sensors are not interchangeable with each other are they? The boyfriend was testing them and not sure if he mixed them up putting them back on. Lol very frustrating situation 

I'm no expert but, if they appear to have the same numbers printed on them, they may be functionally the same.

I guess try them both ways?

 

Hey you are a pretty lucky texan. So changed the cam pulley and she fired right up.  Cant thank you enough appreciate all the assistance. Merry Christmas and happy new year from newfoundland.   Cheers buddy.

 

took until the end of the year for one of my posts to actually help someone!

 

glad it's running.

 ...really thanks again. 

I have a gt to bring in now i just done the engine on her but had no issues. Just doing cv shafts on her ...lol I think I am a subaru junkie ..and I'm sure ill be back got another b4 to bring in and check out fun times

Cheers 

take care, ask questions here - lots of more experienced soob-heads than me here and friendly folks too.

@1 Lucky Texan - bang on the money mate! 

Rule #1 with Subaru engine block changes: always retain the original crank and LHS cam sprockets for this exact reason. 

Glad to read it worked out easy in the end, and I’m sure you are too @Subgirl76 

Cheers
