kerandt Posted April 26, 2009 Share Posted April 26, 2009 Greetings. I am new to the site (and to Subaru mechanics for the most part). I have browsed from time to time, but never had any serious questions until now. So would appreciate any input you guys could give me. I have a '91 Loyale, SPFI, 5-speed with push button 4wd wagon. And am looking at possibly buying a '93 Loyale (5-spd, 4wd wgn) that has a bad fuel pump. Or so the owner was told "might " be why it quit running. Would my '91 fuel pump work on the '93? And is there an "easy" way to tell if the fuel pump is actually the problem? For those of us who are, what I refer to as; "mechanically challenged". The car turns over but acts as if it is out of gas. Wouldn't a timing belt issue act the same way? I will try to find out more details tomorrow when I meet with the owner and actually get a chance to look under the hood. Thanks in advance! -Keith Link to comment Share on other sites More sharing options...
jrfan Posted April 26, 2009 Share Posted April 26, 2009 I'm pretty new to soobs as well but i"m sure the fuel pumps are the same. Easy enough to check the pump and change if needed. Be warned a replacement pump is expensive. The fuel filter is under the hood so easy enough to undo the fuel lines to find out if you are getting fuel to the filter and throttle body. The fuel pump is located under the car just forward of the passenger side rear wheel. good luck. Link to comment Share on other sites More sharing options...
Cougar Posted April 26, 2009 Share Posted April 26, 2009 (edited) Welcome to the forum. To see if you just have a fuel delivery problem spray some starter fluid into the intake. If the engine fires up you have confirmed it. If the engine doesn't fire remove the disty cap and make sure the rotor is turning when you try to start it. A broken belt can cause the shaft of the disty to not spin. I think you can access the wiring to the pump under the rear seat on the passenger side. If you need to test and make sure the pump is getting voltage you can do that there. Some designs use a switched ground design to the pump through the ECU.

DaveT Posted April 26, 2009 Share Posted April 26, 2009 SPFI EA82 1987 = 88 = 90 = 92 use the same fuel pump. Very likely other years also, but I have owned those years. Link to comment Share on other sites More sharing options...
kerandt Posted April 27, 2009 Author Share Posted April 27, 2009 Awesome advice. I will try to look at it closer tomorrow if the owner will let me. Thanks again! Keith Link to comment Share on other sites More sharing options...
somick Posted April 27, 2009 Share Posted April 27, 2009 Before playing with fuel pump open access plugs on the timing belt cover and make sure your timing belt is intact. For the fuel pump, smack it slightly with something and put it back. That might be all you need. Mine has been working fine for about 6 months after that kind of treatment. Good luck, Sam Link to comment Share on other sites More sharing options...
ivantruckman Posted April 27, 2009 Share Posted April 27, 2009 the fuel pump can get bound up if the car sits for a while, ive acquired many Subaru's that way, buy it cheap, than smack the fuel pump, than its starts pumping, and you drive it away. and piss off the previous owner Link to comment Share on other sites More sharing options...

zyewdall Posted April 27, 2009 Share Posted April 27, 2009 Is the 93 SPFI or MPFI? All the SPFI ones are the same, but the MPFI might not be. Check the timing belt first -- checking that the distributor rotor is spinning the best, as often it just strips off a few teeth where it passes around the crankshaft gear, and looks fine other than that. It will have a particular odd sound as it cranks due to no compression on two clyinders, if you're a conesouier of cranking subaru noises (or have seen a number of cars with bad timing belts) Link to comment Share on other sites More sharing options...

kerandt Posted April 28, 2009 Author Share Posted April 28, 2009 Visited with the owner last night briefly. Apparently it ran fine until going to work but would not start at the end of the day. Acted as if it were out of gas. Her son started it with starter fluid and was able to get the car back home (a mile or less). Once parked again, went back to not wanting to start. I've agreed to buy it. So I will wait to investigate any further. My guess is fuel pump or maybe fuel gauge is stuck and out of gas? Thanks again for all your helpful input. Oh, the 1993 is SPFI, everything under the hood looks like my '91. -Keith Link to comment Share on other sites More sharing options...
Scottycocktail Posted April 28, 2009 Share Posted April 28, 2009 Congrats! Love my 93 Loyal (also a 5 speed 4x4). It's required some maintenance since purchase (interior belts and oil seals to the tune of $900, and recently a new battery) but it beats car payments and they are REALLY fun to drive.

ivantruckman Posted April 28, 2009 Share Posted April 28, 2009 if it drives a little like a mile or so ,its probably a fuel filter, Link to comment Share on other sites More sharing options...
kerandt Posted April 28, 2009 Author Share Posted April 28, 2009 The car has had some service recently. Not long before it started acting up. New alternator, some belts, oil change and it looked like a brand new fuel filter too. Maybe they got something in the fuel line? Link to comment Share on other sites More sharing options...
