Soooo... Iv had this car going on 2 weeks now. recently developed a hard start issue. I checked plugs, pulled injectors, I can hear the fuel pump come on, changed the fuel filter, all the sensors look fairly new. The engine spins over fast but just takes a noticeably longer time to start, then the ...

Both those will make you run rich. 22 (knock) will throw the car into limp mode and make it run like absolute shit and be really rich. 23 will also affect that a ton as well, grab another MAF from a junkyard or try and clean yours. THose two codes aren't hard to solve! Really glad you got it runnin...

UPDATE: well after all this time i finally got it to start. after taking some time off with this project i started at step one again. check timing and crank was off. i was sooooo sure my timing was correct that i didnt know i line up the crank with the arrow. so it started but am running really rich...

how you describe your problem i would really solder the wires for the knock sensor and o2 sensor as those are pretty sensitive and nic picky with voltage and resistance. also do you have a cat in your exhaust? sounds like its getting clogged or getting restricted. also why are the knock sensor not b...

definitely not in the books/plans lol

Damn this thread is starting to get me all worked up. Seeing as you have literally checked everything sometimes twice. Sent from my SGH-T989 using Tapatalk 2 yup its a heart breaker thats for sure. but putting this on the back burner for now. dont know what else to do but hope something sparks insi...

but its not.
both diode's tested good.
so now im back to step 1
im about to give up on this and get another wagon .
will report back if n e thing changes.
thanks everyone for all the info.

It will be around where the ECU and fuse box is located.

TYVM for this.
will report back when i get a chance to check it out.

bump any one know where the MPFI Diode is?
seems to be only in the legacy's.

a little update.
while im going thru the wire diagram's i notice this MPFI Diode.
i really think i blew this diode when i cross the batt terminals.
but i can't seem to locate it in the harness.
i've try searching google but w/o luck.
any one know where this diode might be so i can check it out.

I know you said you checking timing, but just to double check, did you use the mark on the back of the crank gear? well i even pulled the timing cover off the cam gear and lining up the harmonic mark with cam gear mark. everything is lining up to where it needs to be. used this for the timing marks...

a little update. finally had time to do some testing. i have all the power and grounds to the ecu. i have compression 145-140-130-125 i know its not balanced but its got enough compression to start tho. still not getting fuel. and if we spray starting fluid nothing happens. not even popping sounds f...

ok im about to give up on my wagon. :( its driving me insane. i've tested two ecu's and still the same problem. have spark but no injector pulse. so this really makes me think im missing a ground so something when i was putting it back together. so my next question is do n e one have a good ground p...

hey this just came to me. does it matter where the map sensor is? and does it matter that its not in the same position/direction? i relocated the map sensor for the tmic install. also do subaru use the logic that if it dont see oil pressure it wont give a injector pulse? been talking to a few of my ...

well the ecu got here and guess what? its not the ecu for me. total bummer. so i need to do a further inspection/test. hope its something stupid i forgot to hook up/install. will report back in a few days since i'll be busy til the weekend or next week. :( man i want my wagon back lol also thanks fo...

hey josh for for the late reply.
i was able to find info in search.
so ecu is on its way so crossing fingers that its going to work for me.

thanks for all the pm's
have one coming so crossing fingers.

can you guys pm me with price shipped to 95037
thanks,

sweet thanks man
will be waiting for your response.

anyone know the part number for the ecu?
i think i found one but want to make sure its the right one.

hi guys
just like the title says
im looking for a auto turbo ecu for my wagon.
its for my 94 wagon but i think 90-94 will work.
but needs to be for a auto.
have a great day
and thanks for looking.

Where did you tap into for fuel pressure? Unfortunately, it sounds like you've tried and tested everything but the ECU, so yeah that's certainly the next thing I'd try. I'd second posting a WTB in the parts shed. i tested at the pressure side with everything hooked up. so i know im doing it right. ...

My apologies, have been using tapatalk all day, just now sat in front of a computer. Did you find a new ECU? is there anyone local that you can barrow their ecu for an hour or so? I would suggest borrowing one before committing to buying one. And if someone suggested that already, apologies in adva...

when i mean ideas i mean new ones lol
if you reread my post youll know that im getting power and are not getting signal.
cant find n e loose/disconnected grounds.
