One more thing---Every time I post a reply I have to log on again . Is that common or is my computor malmalmalfuncioning?

. . .Hey everyone -- subaruLT--the wire from the ECU is on teminal block B58, pin 12 - it goes from ECU directly to the IGN switch before the main relay (to key on) Hope that helps you out. also, A reply to eulogious--- I will NOT delete the thread on this , I'm kinda new on the forum thing and did not know---was just thinking it would be clutter but I see what you are saying, -- Thanx for the tip and to Zefy, -- did the euphorical sledge hammer do any good? I was hoping you'd get it figgered out so we could have more input on the wiring or whatever I did a few experiments with the intake plumbing to possibly eliminate the ugly stock breather tube and found that the ECU does NOT like hope and change (Obamanation)--got the same result as the wire being unconnected-- ECU shut it down in 5 seconds. SOOO . . . Next project will be a 2.5 no turbo which will eliminate the MAFS and thus lighten up the wiring system a bit more (and eliminate the intake tube)- not to mention adding more ponys. Have to go to work now, gotta finish the fab work on the car so I can take it to the dunes!!! (maybe put some brake s on the car--that would be a good thing) So have a good day to all and happy motoring--Or duning!

Hey again---finally got my 2.2 running !! -- don't think my problem is the same as yours but it was the IGN wire from the input side of the main relay to the ECU -- it was not connected Hope you get yours figgered out sooon!! keep us posted and good luck to ya!

yeehah-! ! ! I finally figgered it out ! Spent all day staring at the wiring diagram and chasing each wire down and labeling them till I found the hot wire from Ignition to to ECU ---He missed that one --never got connected to the ign circuit. Hooked it up and it started up and stayed running YAAAAA sounds ten times better than those stupid VW's:banana: been waiting long time to put that dancing banana on this thread!! so now its game on ---time to finish the wiring and shorten the pan and exhuast headers for ground clearance so I can drive it!!! Thank you Thank you and Thank you again to all of you guys for the help on this------all the input and advice was more than I hoped for when I started the thread ---now I know so much more about the subaru than when I started ---awsome---I think I could do it again without help Thanx again to every one--I will delete the thread in a week or so but will keep the USMB on my list of favorites --soopercool website!!

thanx for reply, legacy, I'll start at the top--I disconnected the IAC plug and it started ran for about a second then ran badly for the other 3 or 4 seconds and died -- and the MAF when unplugged has no effect at all---its the plastic body kind I checked the part # at the subaru parts counter and they said it matches the 2.2 from '89 to '99, the 91 legacy (donor car) was an auto trans but it had a button to change to manual shift--? dont know if that makes any sense to you but I'm a nooby to the suby--my first one also . . . this transplant is on a off road - homebuilt buggy so a lot of the excess wiring was deleted -- guages, windsheild wipers , electric windows, transmission wires, ect. A good freind of mine, aka gadget, did the wiring for me and this is the fourth 2.2 single cam engine he's wired with no prior problems (plus a 2.5 and two 1.8 engines)--not saying he's got this one rite but seems to know how to make them work. however . . . considering all the things i'vechecked and tried and the info I've got from the replys on the thread, I'm thinking it may be something in the wiring again -- thanx and have great day ---

this sounds identicle to the problem on my ej22 swap -- Ive tried about everything you have to no avail -- runs great for 5 seconds then shuts off like key being turned off. Hope you get it figgered out soon . . . I'm pullin my hair out too -- and I'm bald

thanx tractor pole I put in a inline fuel p gauge and seems good -- line pressure stays at 50 - (a cheap gauge but funcional) does not flucuate while it is running and dying, also disconnected the IAC wires and tried it, ran for a second then started running badly, then shut off after 4 seconds so the IAC is doing something altho I can't verify its doing the rite thing ?

OK -- I checked continuity from IAC to ECU - all good and pulled the IAC off and made sure it was clean inside-(no dead bugs) ---no changes will try the OBD1 scanner next . . . If I had hair on my head I'd be pulling it out now:eek:

I have a freind with a OBD1 scanner tool --- would that be any help or not since it won't stay running ?

Hello again ! from the replies and reading the thread from the 95 legacy with similer problem . . .I am thinking this must be or related to the IAC so am tracing the wires from IAC to ECU to check for continuity and to make sure the wires are connected properly again - thanx to you guys helping me with this --- hope I can pay it forward soon ! !

forgot to mentoin that I've checked fire at the plugs and injector pulse (exept for pulse duration) and is pulsing and firing even as it dies

Hi numbchux and thanx for the reply--Ifound the term rite b4 you posted reply but notsure what is is--I think its is the valve ith the 3/4 inch vac hose from intake going kinda under the throttle body ? and its hooked up --I even blew out the port where the hose hooks up with air pressure because it was open for a month or so before I installed engine on the vw trans--(to make sure there was no bug nests or dust) and -- its a ej22 from a 91 legacy wagon , other than a miss on #2 cylinder it was running and driving just fine when I pulled the engine and harness--the only thing I missed was the MAF sensor whith I found at junkyard, - Ichecked part number and it is the correct one for this motor also , It does rev ok if I hit throttle b4 it shuts off but time frame is the same --runs almost exacly four seconds then dies like turning key off.

I don't yet know what IAC valve is yet -- I'm a VW guy over 25 years now and this is my first experiance with a subaroo . . . sooo, I need all the help I can get. I do know that everything is hooked up as it was from the donor car and my buddy has sucsessfully done 4 transplants from vw to subaru---this is the first one that did not follow the pattern. I appriciate the reply and look forward to any info you suby guys can throw at me Pete

Hello -- I just registered on to usmb after seeing your post -- I have the same problem with my 91 2.2 legacy engine--shuts off after 4 seconds but I'm not too good with computor--having trouble figgering this forum thing out--I clicked on the 'help' but its not helping me. any avice? I found your posting thru -wont stay running- on google , thats how I found the usmb website.

Help ! sounds ok but shuts off---I'm new to the subaru and don't know much about them yet
