Uberoo Posted March 15, 2007 Share Posted March 15, 2007 got done installing the fuel lines and MPFI fuel fump.I tried to start my ej swaped wagon.I had a friend hook up jumper cables to it because its battery is old and dead.tried starting it about 20 times.almost every time it would sorta fire off a hole.Then I tried spraying carb cleaner down its throat(didn't have starter fluid,also my o2 sensor is not even connected to the exhaust(it has no exhaust).I finally got her to roar after spraying alot of fluid down its throat while flooring it.But it died as soon as I stopped giving it fuel.Right now it will hardly run,will not idle(can't even get it to stay running that long)indeed the longest it ran was a second.Right now the fuel pump is powered off the EA harness.I will connect the ej wire to it tomarrow.Also tomarrow I will change the plugs as they are probally fouled like all hell becuase it sat for 4 months+ however long it was at pull and save.So after I get the the EJ fuel wire hooked up and new plugs do you think it might work?keeping in mind the o2 sensor is reading 73% oxygen or however much oxygen is in the air... wish me luck... its a shame I missed my appointment with the college welding shop to have them put an exhaust on it...

mikeshoup Posted March 15, 2007 Share Posted March 15, 2007 It should run without the O2 sensor. Whether it'll run after you hook the fuel pump up to the EJ harness and change the plugs, only one way to find out. Link to comment Share on other sites More sharing options...
WoodsWagon Posted March 15, 2007 Share Posted March 15, 2007 Right now the fuel pump is powered off the EA harness. There's your problem. The EA harness turns the pump off if it doesn't see that the distributor is rotating. Since you no longer have the signal from the disty, no power to the pump. I found splicing in under the back seat for the fuel pump wiring was the easiest. Link to comment Share on other sites More sharing options...
Uberoo Posted March 15, 2007 Author Share Posted March 15, 2007 Does the seat flip forward?I know it bends forward but does the whole seat swing out? Link to comment Share on other sites More sharing options...
Numbchux Posted March 15, 2007 Share Posted March 15, 2007 Does the seat flip forward?I know it bends forward but does the whole seat swing out? on an EA82 wagon right?! yea, the bottom flips forward so the backs can fold down flat. just fold the bottom forward, and on the passenger side there's a rubber boot where the fuel pump wires come through.

Uberoo Posted March 16, 2007 Author Share Posted March 16, 2007 today was a waste of time.I tried to wire the ej wire to the pump.Fore some reason it wouldnt even spin after that...Then I wired it straight to ignition + .Only problem was I wired it to the ignition plus that comes into the switch not the switched lead off the back of the switch which mean my harness has power almost all the time.Anyway when I wired it in the fuel pump would just stay running even with key off.So I tried to start it.Still no go.So I cut the wire I had just wired in.Then I undid the fuel supply,expecting gas mist or high pressure gas spray out.It was BONE dry.Then I had a friend listen at the fuel tank while I blew into the line.It was just a blowing sound instead of a bubbling sound which means someone pilfered my 2 gallons of gas that were in there while my car sat for a long time...so tommarow I have to find legacy upper and lower radiator hoses,2.5 gallons of gas and a toggle for fuel pump(it will be up in the dash somewhere.Not out in the open.Should be a good anti theft measure...)

Phizinza Posted March 16, 2007 Share Posted March 16, 2007 The EJ loom runs the fuel pump for about a second when you turn the igntion on to prime the line. Then it stops, and when you start the car the ECU turns it on while it detects engine rotation (I think..) Although, the fuel pump does not need to be connected to the EJ loom for the engine to run (I had it just constant on in my first start up.) But I highly recommend getting the ECU to power the fuel pump. Because it doesn't like running unless the engine is running, something to do with the pressure regulator running off of vacuum.

Numbchux Posted March 16, 2007 Share Posted March 16, 2007 I highly recommend getting the ECU to power the fuel pump. me too. I think that would be a very good idea. Link to comment Share on other sites More sharing options...
Uberoo Posted March 16, 2007 Author Share Posted March 16, 2007 when I connected ej fuel wire to the pump it didn't even move.It didn't whirr into life for a second or anything just nothing.so I will just wire in a toggle,maybe even use it as a killswitch.

Phizinza Posted March 16, 2007 Share Posted March 16, 2007 Just don't stall your car and leave that switch on for too long. I get the feeling it wouldn't be good for the pump. Link to comment Share on other sites More sharing options...
mikeshoup Posted March 16, 2007 Share Posted March 16, 2007 Also, be ready to flip that switch off in the case of an accident. A reason the computer controls the fuel pump is so it can cut fuel when it doesn't see an ignition signal. Thus preventing fires and such in the case of an accident.

Hmm, 40PSI of fuel pouring out into your engine bay on fire would be an interesting sight.. Oh, and make sure you do what I did... http://offroadingsubarus.com/images/ej22swap_fire_extinguisher.jpg Does the fuel relay tick when you turn the ignition on?

Numbchux Posted March 16, 2007 Share Posted March 16, 2007 the fuel circuit is one of the simplest ones in the harness, if this one doesn't work, something else won't work either. make sure there is power going to the relay, and continuity to the pump, from there, it's just one wire to the ECU. and if the ECU isn't grounding the fuel relay, it probably either doesn't have power or ground somewhere, or no signal from the crank/cam angle sensors. if it comes on with the ignition, but not while cranking....it's probably the sensor. and if it's not coming on at all, it's a power/ground somewhere.

Uberoo Posted March 17, 2007 Author Share Posted March 17, 2007 today was also a waste of time.I found some 1.5" id hose at schucks that was long enough for both upper and lower hoses.The upper hose was a pain and a half to fit because the power steering lines where right where it needed to be.Then when I tried to fit the hose clamps on I found out that the max diameter the hose clamps could go was the same diameter or slightly smaller than radiator hose OD. after spending an hour just to get the upper hose on I finally got everything to go on.Then I move to the lower one.I go to fit the hose on the radiator but there were some kinks in the hose so I tried torotate the hose so the kinks would even themselves out.The lower radiator outlet BROKE OFF!!Much cussing ensued.By this time the shops/banks were closed so I was SOL.Does a lower radiator hose on a loyale radiator come straight out or does it kinda loop around?If it come out straight it would be perfect.But I managed to wire the toggle in.wasnt able to get gas though. what is worse is the fact that I got out of school at 2 today instead of the normal 3:30 for spring break and I still couldnt get stuff done..
