Bubonik Posted March 22, 2005 Share Posted March 22, 2005 ok now i'm kinda stumped my '90 loyale has been acting a little weird the last few days {well, since i got it really. just more so now} it started with.... i'de be driving along and it was like i took my foot off the gas without doing anything then a few seconds later it would come back like i put my foot back on the gas yet i didn't move my foot at all {maybe more gas if anything} now, in the last few days it has started to be like that every time i leave a stop light or anything but more like on-off-on-off-on-off for about 30 seconds than it would get better it gets better as the day and the car get warmer but first thing in the morning i could walk faster than i can get the car to go !! i thought it may be the clutch slipping i looked up all the cluth testing and setting threads on the site {lots of help !} did all of that stuff and the clutch passed with flying colors ! everyone else i have talked to about it says it sounds fuel related since you guys are the people in the know for Subes any ideas ? anything i could try to see if it is the fuel ? anything else i should be looking into ?? ANY help i could get would be great !!!! i want to take it camping at china beach in three days !! :{ thank you !! Quote Link to comment Share on other sites More sharing options...
MorganM Posted March 22, 2005 Share Posted March 22, 2005 My guesses would be Mass Air Flow sensor (MAF) and/or Throttle Position Sensor (TPS) With the MAF the engine is getting weid signals (or signal is dropping totally) on how much air is entering the system and therefore it sends improper amount of fuel. Same with TPS, engine thinks the throttle is at a certain point, then signal drops and computer tries to compensate. I'd almost look for a loose wire or connector at these devices. Might be wiggeling and when it does you are getting the symtoms judgeing by how random it appears. Good luck! Quote Link to comment Share on other sites More sharing options...
Cougar Posted March 22, 2005 Share Posted March 22, 2005 First thing you might try is change the fuel filters and have the fuel pressure checked. It sounds like a bad fuel pump but try the filter(s) first. Quote Link to comment Share on other sites More sharing options...
85Sub4WD Posted March 22, 2005 Share Posted March 22, 2005 First thing you might try is change the fuel filters and have the fuel pressure checked. It sounds like a bad fuel pump but try the filter(s) first. I think you are right, we had the exact same prob with my '85 soob when it was carbed - sounds like fuel delivery to me too.

MorganM Posted March 22, 2005 Share Posted March 22, 2005 Good call on the fuel pump. Again start with an inspection of the wires. Could be wiggeling and loosing connection randomly. Might just be on its way out Quote Link to comment Share on other sites More sharing options...
Bubonik Posted March 22, 2005 Author Share Posted March 22, 2005 ah you guys rock !! {and gals too !} i did one of the filters already but there are two right ? i'll start checking all the stuff when i get home and post as to what i find thanks again Quote Link to comment Share on other sites More sharing options...
MorganM Posted March 22, 2005 Share Posted March 22, 2005 i did one of the filters already Naw, just one up under the hood on your Loyale. Quote Link to comment Share on other sites More sharing options...
Bubonik Posted March 23, 2005 Author Share Posted March 23, 2005 well all the wires/connectors i could find seemed fine i still have to get under the car and look at the fuel pump i forgot to mention this .... the revs don't change as all of this stuff happens doesn't drop or raise just the gas/nongas feeling does that still point towards the pump ??

MorganM Posted March 23, 2005 Share Posted March 23, 2005 certainly could be the pump on the fritz. more likely the wires there at the pump. the whole thing is very prone to the elements and rust down there behind the rear main crossmember on the passangers side. the wires going upto it are pretty wussy and the teriminals on the pump are equally wussy. could be jiggeling loose at the teriminals on the pump. mine was so rusty when it finally died that parts of it disinegrated in my hand from just inspecting it! good luck.

FlyB0y Posted March 23, 2005 Share Posted March 23, 2005 I'm not at all farmiliar with the loyale, and I'm assuming it's an ea-82 with fuel injection? well, I don't even know if it would have a vacuume controlled timming advance or not, but I had a vehicle that did this very same thing, and all it turned out to be was a failed vacuume advance on the distributor. Someone know if this would even be a posibility on this engine? Just throwing an idea out there for the experts to look into Quote Link to comment Share on other sites More sharing options...
Bubonik Posted March 23, 2005 Author Share Posted March 23, 2005 it is {EA-82} and it does {have fuel injection} does that sound like a possibility to anyone ? and how would i look into that ? and i'm going to get under the car and look at the fuel pump tonight ...... than i may have to find a cheap still good second hand pump ..... to expensive new :{ Quote Link to comment Share on other sites More sharing options...
MorganM Posted March 23, 2005 Share Posted March 23, 2005 No vacume advance on your distributor; it's an optical distruibutor. There is a cheaper alternative to the Subaru fuel pump. I've just submited a USRM article describing how to install it and what part # it is. Hopefully that will get approved soon. Basicly its napa part #2p74028 and you can make it work on your Loyale with minimal modifications. Price ranges from $45 to $75 but it beats $255 for a new Subaru one. Is your Check Engine Light on by chance? That would shed some light on the situation Quote Link to comment Share on other sites More sharing options...
Bubonik Posted March 23, 2005 Author Share Posted March 23, 2005 no check engine light at all VERY occasionally it will ide really poorly {read: rev up and down a whole bunch} and the light will come on but go away after it clears up about 20 seconds only done that about 3 times since i've owned it i never remember to get the code {it goes away and i forget} but no light at all when it does the gas-nogas thing I hope your fuel pump write-up gets on soon !!! 50 bucks (90 canadian) is much better than 100 used or 300+ new :{ you could email your write-up to me if you'de like :} reedk@camosun.bc.ca thanks alot people !!!

Bubonik Posted March 23, 2005 Author Share Posted March 23, 2005 ok so out of curiosity i phoned NAPA here to see how much that fuel pump was the dude told me "you must have gotten that number off the 'internet'" not one of our part numbers so now what ?? it must be hes just on glue or something !

Bubonik Posted March 24, 2005 Author Share Posted March 24, 2005 well the conector on the fuel pump was definetly loose don't know how long it'll hold together but i connected a good as i could i'll have to see in the next few days how it's going to be .... also how do i post a picture ? i took a picture of my connectors under my dash {i was trying to pull codes} all i got was 'make and model' but i'm unsure which connectors are truly which and exactly which ones should be hooked up when all the combinations i tried gave me 'make and model' and that was all if i can get the picture up maybe someone can give me exact details ..... i've looked at alot of the pulling codes threads and they say things like "test-mode connector" clear memory connector and such but what are the colors ? are they the same on every car ? i heard from here somewhere that some of the stuff is the same on every car and some the wires and such are different colors from car to car how much of that is important ?

That guy is a tool then. Try and get someone else on the phone. If they still cant conjure up that part number then tell them you want a fuel pump for an EFI Ford F150, early 90's, the one that has the intake pump and an inline pump closer to the engine. YOu want the in line pump that costs no more than $75. They will of course want to sell you the $150 one. =P You should be able to upload photos to the Photo Gallery in the upper left corner.

Click on My Gallery and Album Admin. PM me if you need more instructions. The colors of the wires do vary I have noticed. On my Loyale under the Steering wheel behind the trim below the steering whell housing is the Wires and the ECU. I had to take of that trim to see the ECU Light. Find the Code Instructions from legacy777 ( Josh) It should give you detailed info. If you have trouble finding the wires let me know and I will cjeck it out when my wife gets back.

KStretch55 Posted April 1, 2005 Share Posted April 1, 2005 I just looked up that P/N on NAPAonline, and sure enough it's there. Looks very similar, except for the 90 degree outlet pipe and damper that's built onto the Soobie original. But, hey there's several more dampers along the line anyway, right!!? It does say "Pressure rating, 4 - 6"? I presume that's some kind of rating system not output pressure. Looks like a good alternative to me.
