#63 of 132 Intermittent fuel problems - 1995 Legacy by nrabek Apr 02, 2007 (6:37 pm)
I have a 1995 Legacy which has 180,000 miles, and, until now, no major problems. Last week the fuel pump suddenly stopped delivering fuel consistently. The pump no longer runs the second or two when I first turn on the key, except occasionally. I tested the relay, and it worked. I pulled the pump and it runs fine outside the tank, when plugged in to the control wires for the tank. If I hear the pump run up initially and start the car, the car will continue running. Otherwise it won't pump any gas and no matter how long I crank it, it won't start and the pressure won't build up. It has fuel injection. What am I overlooking? Is it a weak pump that can't maintain pressure or a problem with the computer control? Whatever it is, it is driving me nuts. Thanks for your help.

Replying to: nrabek (Apr 02, 2007 6:37 pm) hmm, is the pump running when it's stalling or is the pump cutting out? I think it might be a relay problem. Perhaps a fuel injector? Did you recently get 10% ethanol fuel in your area? If so it could be the sock at the bottom of the pump is clogged. That's a start, let us know what you figure out.   -mike Replies to this message: nrabek (Apr 02, 2007 7:39 pm) paisan (Apr 03, 2007 3:18 am) nrabek (Apr 03, 2007 4:24 am)

Replying to: paisan (Apr 02, 2007 6:43 pm) No, the pump doesn't run much now, only when it wants to. So, the engine will start but immediately die. It has a tank full of regular gas with no ethanol. When I pulled the pump, the sock was fine, and, as long as the pump was out, it ran continuously while connected in the circuit with the relay and all. Not problems till after it was submerged back in the gas tank, and the key was turned on several times. Then it refused to pump at all, until it was pulled again. I have continuity on the relay on the control side, but when it acts up, the relay doesn't "click" to complete the power side till the control side is grounded. I can jump the power side of the relay and the pump will run fine outside the tank, but not when in the gas. Replies to this message: paisan (Apr 03, 2007 3:18 am) nrabek (Apr 03, 2007 4:24 am)

Replying to: nrabek (Apr 02, 2007 7:39 pm) Seems from your description that it's a ground or power issue to or from the relay. How about replacing the relay it's a fairly in-expensive item to test out to see if that's your cause. My guess from the data provided is that it's not the pump or the lines at this point but rather either the relay, the ground for the relay or the power from the relay to the pump itself.   Have you tried the pump connected up but physically outside the tank but connected to the car's wiring?   -mike Replies to this message: nrabek (Apr 03, 2007 4:24 am)

Replying to: paisan (Apr 03, 2007 3:18 am) Yeah, I have pulled the pump twice now, and both times it runs outside the tank. It just runs for a second or so when the key is turned on, like it is supposed to, but if I jump the power side of the relay it will run continuously. When I test the relay by energizing the control side, the relay works and closes the circuit on the power side, so that part seems to be functional. When I check for voltage at the relay, I have 12 volts at both leads going into the relay, but the line leaving the relay has only a minimal amount of voltage - from 1/10th to 1/2 volt. This is with the key on. While the test the manual gives for checking the relay - energizing the control side - seems to indicate that the relay is good, I am with you on replacing the cheap stuff first. The pump is $100. Thanks. Norman
#68 of 132 Click but no engine turnover by phil34 May 11, 2007 (8:28 am)
I have an intermittent problem with my '94 Subaru Legacy...when turning the key, I hear a click but the engine does not turn over. Several tries and it may or may not start. Dealer guesses it is the starter because they could not duplicate the problem and wants to TRY starting there for the tune of $350. Any suggestions that may cause this behavior.

Replying to: phil34 (May 11, 2007 8:28 am) Starter should run about $90-120 and you can install it in about an hour, as it's right on top of the engine.   I would check the grounds but you may have a bad starter, seems like it's not engaging properly.   -mike
#70 of 132 98 won't start- again!! by cptplt May 15, 2007 (6:38 am)
so my 98 legacy GT (135K) with new plugs and wires at 120K, new battery around Xmas and new starter this year, wouldn't start. all electricals work fine but not even a click. it had done this intermittently the last year (hence all the various work done) but it usually would start up after you turn the key several times. new starter went in when it started to do this several times a day rather than once every few weeks. since new starter in ? January, it has been perfect , till yesterday. Tried over an hour to see if it would start, nothing, though all electricals seemed fine, tried jumping it, nothing. Didn't even seem like fuel pump was whirring when key turned. Called AAA and while waiting said a prayer and tried again. Of course now it started just fine!! Drove it to my mechanic who's looking at it right now. There was that one time last year when the negine kept running when the key was in the off positiion! Is it the ignition key switch?? Good thing I'm getting rid of this soon (as soon as they start delvering 2.5OB with VDC to the dealers). there is a line of people who want the car but I don't want to sell, or even give them something which will leave them stranded somewhere. PS never get stuck in a parking ramp with 6' 7" clearance, not many tow trucks can get it!! Replies to this message: xwesx (May 15, 2007 9:22 am)

Replying to: cptplt (May 15, 2007 6:38 am) While it is surprising to me, I think that the ignition switch is the most likely culprit in your case. The one on my '69 Econoline is going out. While I have never had it not start, it will often not turn off.   From the sound of it, it is giving you nothing - not even electric for your windows, etc... is that right? Since you said it did not seem like fuel pump was turning on, I would guess nothing else that should come on in the "ON" position was working either.
#72 of 132 it was my cellphone??? by cptplt May 17, 2007 (10:22 am)
all the electricals work (very well) which is what got me puzzled well, car got checked out, all electricals seem fine, couldn't reproduce the no start. had a CEL a few weeks back P1507 and they cleaned the engine idle sensor or something. thinking back, the car started up after I had tried to get it into N and try push it out of the parking space as the AAA lady was despairing of ever finding someone who could get their truck into the parking ramp. I usually put my cellphone in front of the gear shift and I know sometimes when I put it in P, it jams up against it. maybe it wasn't quite in P and the Neutral safety interlock switch or whatever had me cut out so engine couldn't start. when I fiddled with it to get into N to try push the car it must have gone back into P properly and then worked!!! well I 'll be more careful about getting the gear into P and see what the future holds!
