Locate the fuel pump relay(probably in the underhood fuse/relay box).The next time the pump stays running,thump that relay to see if the pum turns off,if not,unplug it and swap it with one of the other relays to see if it comes back on.

it sounds like either your having a short at the starter or the ignition switch is bad, I am leaning towards the issue being the starter, usually when the ignition switch is going bad there will be no click,

Subaru Outback Legacy Flashing
Q. I have a 1996 Subaru Outback Legacy AWD manual transmission. the hazards flash when I turn the car off. I tried to reset the system by pushing the little black button under the drivers' side dash but it won't reset the system. I had problems with the brakes so I did not drive it for about two months and when I tried to start the car the battery was dead.
mechanic.jpg Now the brakes are fixed but the hazards won't quit flashing and the guy who repaired the car said I needed to reset the system by pushing the little black button. And I don't know if I should have it looked at, or change the battery, or if it is something very simple I can fix by my self.
Thank you very much,
A. Patrick, you are the third person in the last two days that has come to me with this same exact problem under the same conditions. As of now I don't have any concrete information on this, but I believe the problem to be in the alarm system.
I believe the battery being disconnected or dying does something to the Anti-theft and Alarm System module and having a Subaru dealer reset the system will correct it.
If you do this and it works, please, let me know and I will pass the information on to the others.

Dear Mr. Ciulla,
I read your Q&A titled "Subaru Outback Legacy Flashing". I recently had the same problem on my 1996 2.5 liter Subaru Legacy Outback and your response is correct but I can give you a little more detail on what worked for me to stop the light flashing (which occurs sometimes if the battery had been dead):
There is a black reset button under the I/P near the anti-theft module.

  1. Turn ignition on
  2. Hold button 20+ seconds (door locks will lock/unlock 3 times)
  3. Turn ignition off
This also resets the key FOB so as step 2.5 you should also press the "lock" button on the key FOB before releasing the black reset button (door locks will lock/unlock one more time--do this with each key FOB you own). That's all!
The questioner in your Q&A said he tried the reset button; I suspect he either didn't turn the ignition on/off or didn't hold it in for over 20 seconds.
PS... pulling the door lock fuse will stop it temporarily if you can't get the above to work and have to take it to the dealer

sounds alot the the pcm it controls the fuel pump and ign system but the anti theft would keep it from starting because the key has a transponder in it programmed for that vehicle and that would kill all ign if triggered

Fuel pump sensor draining battery?

The things that you need to do are:
1. Drop the gas tank, this is not easy and it is dangerous. Make sure that it is empty and that there are no sources of ignition around. You need to unhook lines that connect to it that are both fuel and electric. The big lines to the filler neck are hard to unhook and when you are done you should seal them with permatex.
2. The battery draining issue requires that you use an amp meter on the battery in series with the cable. Then you start pulling fuses to see what makes the reading drop. Make sure that you have a meter that will read amperage and not milliamps or you will blow out the meter.

Won't start. I've replaced the fuel filter, the spark plugs, wires, and ignition coils. Will run off of starting fluid, but not by itself. Checked fuel pressure and it's coming up around 40. What else...

Start and run about 5 sec

the most likely problem is the fuel pump has stopped working. a simple test is remove the gas cap, have someone put their ear near the gas filler opening, turn the ignition switch to the on position, if the fuel pump is working you will hear a humming sound for 2 or 3 seconds. this should happen every time the ignition is turned on. if no sound is heard you need to check the
fuse , the fuel pump relay & some vehicles have a safety switch, so if the car is in a crash the fuel pump won't operate

2000 Oldsmobile Intrigue - intermittent starting, starts fine in the morning (usually) arrive at destination and when time to leave will not start or engine dies. Sounds like it will start but doesn't, not...

No. Your description could be several issues. You need to determine if the ignition is coming on when the problem occurs or not, this will eliminate the ignition side of the system from being the problem.
I suspect that the fuel pump is not running when this occurs. Next time this problem happens, just turn the ignition on and listen for the fuel pump. It should run for a short time and then stop. I had this same symptom and it was the wiring (ground wire) going to the fuel pump. Took a long time to actually figure out exactly what was wrong, but we haven't had a problem since.

How to change fuel filter on 1996 Honda Civic

It is located Under hood, center, upper firewall, mounted in fuel line (basically back of dash). Take note of how it is mounted not to install backwards. Unhook battery ground. Unhook two fuel lines one on top one on bottom of filter.Mark fuel lines top/bottom tape helps not to get mixed up. Remove from clamp. place new filter in clamp noting proper top and bottom. replace fuel lines. reattach battery, cycle key on and off 3 times slowly. (when you turn key foreward you will hear pump kick on. when stops turn off. Do again 2 more times then start.

Car wont start

THere is no gas in the fuel rail at the time gas is running out. WHen you fill the tank, it needs to pump for a while so fuel can fill up the rail then the Fuel distributor so it can build up pressure for the injectors to work properly. It need to continue cranking at least 2 minutes. However you don't want to run out the battery, so can just turn on the key to hear the sound of the fuel pump stops, then turn key off turn key on again. Repeat this for 6 times then start the engine. The reason for it is that every time the key is on it turns on the fuel pump to prime the line then turns pump off after a specific time, then it turns on again only when key is at ignition position. By doing this you help to pump gas into the fuel rail instead of the starter continue cranking draining down battery fast. Cheers.

You mite have an ignition module problem but it sounds like your fuel pump is not working. Have some one turn the ignition on as you listen for the pump switching on
