99gtott Posted May 18, 2010 Share Posted May 18, 2010 (edited) Just finishing up a swap and have a few questions. Swaping from a 2001 impreza ej22 phase 2 auto trans into a 1999 impreza OBS ej22 phase 2 5sp. Got the old one out, new one in and all hooked up, it turns over but wont start. getting gas but no spark. I've double checked all connections/fuses. I'm wondering if i need to swap the whole intake system back to the one that came on the OBS. Then i could use the sensors/relays (what are these?) that hang off the pass side strut tower. Has a vac line coming off it also. The 2001 doesnt have these.. Is this right? Should i exchange the whole intake? Thanks!

subaru360 Posted May 18, 2010 Share Posted May 18, 2010 Swap the whole intake and also check the back of the cam gear on the drivers side where it triggers the sensor, count the teeth that trigger the sensor. There are two different ones. Quote Link to comment Share on other sites More sharing options...
99gtott Posted May 18, 2010 Author Share Posted May 18, 2010 thanks for the intake swap advice. and what am i looking for by counting the teeth that activate the sensior on the cam gear? might i need to swap this also? any ideas about what the relay/sensors are that mount on the pass side strut tower? thanks again guys!

subaru360 Posted May 19, 2010 Share Posted May 19, 2010 If the cam gear is different, the car won't start, so you need to swap it. Use the complete intake from the original engine. That will have all the connections needed for the sensor and solenoid on the strut tower. Quote Link to comment Share on other sites More sharing options...
Gloyale Posted May 19, 2010 Share Posted May 19, 2010 Devices on the strut tower are a MAP type sensor and switching solenoid to switch it in and out of the loop. I'm running a 96 Legacy 2.2 and harness/ECU in my old GL. The donor car was wrecked and those sensors on the strut tower where destroyed. The car runs fine without them. Betting you're problem is the Cam gear on the drivers side. Quote Link to comment Share on other sites More sharing options...
idosubaru Posted May 19, 2010 Share Posted May 19, 2010 "swapping from a.....into...." i'm finding it hard to figure out which way you went and if you're talking about engines or trans or both. i'd read check engine codes and check for obvious vacuum leaks like the brake booster. as a guess reading confusing information I'm with Gloyale the cams likely need swapped.

99gtott Posted May 19, 2010 Author Share Posted May 19, 2010 thanks for the info. not sure why that was confusing to some. i thought the "from" and "into", would give it away? regardless, does anyone know how to tell if the cam gear is the issue? do they need to have the same # of teeth or? and maybe the proper procedure for swaping out the cam gear and what this intails? again, thank you for the help!

idosubaru Posted May 19, 2010 Share Posted May 19, 2010 Any check engine codes? I would install all the intake that was originally in the car like subaru360 suggested, did you give that a try yet? As for the cam sprocket, remove timing belt, swap cam sprocket, reinstall belt. Quote Link to comment Share on other sites More sharing options...
subaru360 Posted May 19, 2010 Share Posted May 19, 2010 Break the cam pulley bolt loose before you take the belt off. Lots easier that way. But count the teeth on the back first, if it's the same, no need to swap them. Quote Link to comment Share on other sites More sharing options...
99gtott Posted May 20, 2010 Author Share Posted May 20, 2010 thanks again guys, i've got the day off tomorrow so i'll be able to get to it. keep ya posted! Quote Link to comment Share on other sites More sharing options...
99gtott Posted May 21, 2010 Author Share Posted May 21, 2010 so swaped out the intake. had to wait a day for new gaskets. everything is plugged back in the way it origionally was. it turns over and farts a little but thats it. i counted the notches on the back of the drivers side timing pully and ya, there diff! the 2001 motor has one notch and the 1999 has six. so i just swap out the drivers side pully and it should be good to go? sound about right? i'll post again.. thanks again!

logic23 Posted May 23, 2010 Share Posted May 23, 2010 the crank gear will be different too. swap it or the engine will continue to fart and backfire. Quote Link to comment Share on other sites More sharing options...
99gtott Posted May 23, 2010 Author Share Posted May 23, 2010 really? thats why it's still not starting? oh man i wish i would have known this yesterday.. i just swaped the drivers side timing pully, got everything marked up and back together. it still coughs and wants to start but doesn't. so if i change out the crank pully it should fire? they are a little different? you've had to do this one a swap before? good info my friend! thanks again everyone!

99gtott Posted May 23, 2010 Author Share Posted May 23, 2010 still won't start.. the crank gear pullys look identical. does anyone know what the difference is between the two? all marks are lined straight up, everything should be a go. any ideas? thanks!

There are 2 different crank gears. One has about 20 small teeth on the back where it triggers the crank sensor the other has about 5 large teeth. The difference is obvious.
