Hi all,

From reading this forum, I've deduced that the relay is behind the glovebox. I've pulled that out, but not sure what it looks like. Is it the square (more rectanglish) shiny metal box to the left, about 3 inches long?

I know it's a newb question, but this is my first magna, I'm used to relays being in the engine bay!

cheers.

welcome to the club mate
that sounds like an efi fuel pump relay

Thanks mate, I should have said it was a 4 cyl EFI. So it will just bolt out to be replaced?

yea there easy to replace
any efi gen1 gen2 relay will do if you go to the wreckers just look for one that looks the newest

Awesome, thanks mate.

When I actually owned a 4 cylinder second gen, I kept a spare in the glovebox with a philips head screw driver and 10 mm wrench, just in case . . . . lol

So, I went to a wreckers and they gave me a black plastic box with a wiring plug. The box has clips that comes apart to reveal a small circuit board. Is this the relay? They reckoned it was. My car has one but it is straight behind the glovebox.

Hi,

No the one I got from the wreckers is exactly the same as the one in my car, even has the same sticker marked Denso. I've attached a couple pics.

Thanks for the help.

OK thanks mate, in that case it isn't the relay causing my problem. Car still won't start. I'm going to check for fuel at the rail next, I suspect it might be the pump.

Thanks for the help.

have put power to the pump
or get under the car when someone turns it over see if the pump runs

longman

Yeah will do that tomorrow when it's light. thanks.

if you have a spare battery and two wire,s
undo the plug at fuel pump. the black yellow wire is the positive see if it runs
left field how old is the fuel filter

longman

Not sure on the filter, but I have a new one to go on, so will do that too!

Resolved:

Turns out it was the relay. Had a mate helping to try jump start it when it first died, he flicked a hidden kill switch under the dash and didn't tell me. Eventually found it, flicked it on and away she went.

Thanks for all the help!

i know what that's like spent a day working on a tr change ecu dizzy fuel relay fuel pump coil pack
found a micro switch under the dash . would have been nice if the seller had told me it had a kill switch

That reminds me. My TS has one under the dash somewhere too. Previous owner told me about it, 5 years ago. Must have a look soon, and remove it. I hate these little undocumented modifications some people do. Often badly installed, and send you on a wild goose chase if it goes wrong - as you found out.

UPDATE:

For any interested owners, disregard the pics in this thread. Turns out the relay was stuffed, however the item that was identified for me as the fuel pump relay via my photos was in fact the aircon relay. The fuel pump relay is the rectangle metal one behind the glovebox to the left.

Newbie here.......basic question, Where's the fuel pump plug? My daughters '95 Magna (carby) 4cyl, apparantly just stopped (whilst having a service at a mechanics). They claim it'll be $300 for a new fuel pump.

I've found a plug in the boot against the back seat. No power there and colour code doesn't match what others have said either.

I've found a spade terminal under bonnet but that doesn't really match the location that others have suggested either, but it does energise on ign. I've tried to backfeed this with +12V but no sound from fuel pump.
http://i204.photobucket.com/albums/bb286/swanning_it/IMG_1531.jpg

And I've found two relays under the carpet behind the glove box but neither match the wiring colours to what I'm assuming is the pump plug and neither are metalic relays like the FPR is supposed to be.

Any help or suggestions? Wiring colour codes, harness route, locations?? Is the fuel pump wiring protected by a fuse and if so where is it? Is the pump in the tank or external?

Sorry for all the questions but working on cars on my day off is not really my idea of fun! Many thanks.

On the TS EFI 2.6 the fuel pump relay is bolted to the front rail on which the glove box inner liner sits, it's nowhere near any carpet. It's definitely a metal encased box.

The fuel pump energiser sits on the engine compartment firewall, passenger side, high up. It's next to a round capped plug that is used to set ignition timing. The fuel pump connector goes to battery +, the ignition advance cut goes to earth or battery -.

That's all I remember, it's been a while since I owned that car.

If it is a sedan, the fuel pump and it's wiring can be reached by lifting the base of the rear seat, I don't think the wiring is in the boot. (IIRC, someone flame me if this is not correct)

On a carby model, the fuel pump is a low pressure unit located in the tank.

The relay photo on the left above is the one that was bolted to the front rail on which the glove box liner sits. Maybe that's it than?? Definitely not metal cased if that's the one.

Yes, I've seen that said elsewhere (possibly by you as well). On this one, there are no plugs in the engine bay passenger side high on flywall. The one I photographed was maginally forward of the passenger side wheel arch under the bonnet. It's the only one within cooee of where you suggest.


If it is a sedan, the fuel pump and it's wiring can be reached by lifting the base of the rear seat, I don't think the wiring is in the boot.

I've lifted the rear seat......nothing there at all. The plug in the boot (photo one above) disappears into a grommet (about 2.5" wide) which seems to access the fuel tank below....but perhaps I'm wrong there.

I'm wondering if we're talking about the same Magna? November 1995 build, GLX, 4 cyl, carby delivered sedan.

the photo on the left is a carby relay .
is it wagon or sedan
max was talking efi energiser
you can test the fuel pump under the car. black/yellow is the positive wire
and welcome to the club

Thanks for the welcome.

A carby relay?? What's a carby need a relay for?

But back to the fuel pump relay, if everyone insists the FPR is mounted to the rail the glove ox liner sits on, then perhaps someone has removed it and tucked the plug and harness up out of the way? Possible? Tomorrow I'll have a feel around and see. Magnaman the plug in the boot is not the pump then? Does the fuel pump relay get it's feed from under the car? Perhaps the one in the boot is the fuel gauge wires.

sorry most people have stayed away from carby cars.
fpr is on the left where ecu would go on the efi car
i would check the pump first the plug is under the car two wire,s if you have a spare battery test the pump. if pumps working then go fpr
if you need a pump make sure you get a carby one as the efi pump run a higher pressure
carby relay is fpr

OK thanks for that, so the photo on the left above is the carby relay that = the fuel pump relay, which is under the glovebox to the left?? (Which is where an EFI ecu would go??)

Wow, confusing.

Thanks for the info. Are carby magnas problematic?

my grammar,s is crap lol . where in qld are you. magna buff has some carby detail,s in the gen 1 section witch may help you
have you connected power to the pump . again check the pump first

Gold Coast. I'll check the pump again as it seems what I thought were the pump wires, aren't! Thanks for the helpful replies!
