1994 D-90 Will Not Start-fuel Pump?

Hi; My 1994 d-90 will not start and I think the fuel pump is bad. I checked the fuse. I disconected the fuel line after the fuel filter and turned the key, no gas is flowing, is there a modular that could have gone bad or is that just wishful thinking?I want to fix it myself but, I saw in the repair manual that you need a certain tool for the ring that holds the pump in? I want to fix it myself but I could do all this and that was not the problem- I am pretty sure it is. What are your thoughts on doing the work myself- PLEASE.

Before replacing the fuel pump you might want to check the relay. I'm not sure if the D90s have a fuel pump relay or not (I know the Rangies and Discos have one). Also check all electrical connectors going to the fuel pump.

Your fuel filter might be clogged also (you checked the fuel pressure after the fuel filter).

Good luck.

When you turn the key to start...Do you hear the pump come on?

I've done fuel pumps on RR and Disco and they were very easy to replace. I even used a Caddy pump ($80) on my RR and it worked fine for 5 years.

Like 4WD said, you should hear the pump running when you turn the ignition.

Is the Defender at your home or is it stuck somewhere?

Well, if you need a pump or help I'm not too far from you.

I am pretty sure there is a relay. If you have the service manual, it will tell you which relay is the one for the fuel pump. They are located in the cabin, behind the panel which is forward of the shifter.

Before ripping out the pump you can test to see if it's bad or not by running a jumper wire from the battery (or, positive alternator connection point) to the fuel pump positive terminal. I always keep some 16 gauge wire around with alligator clips on it for just such testing (something you can grab at your local auto parts store cheap, but you don't really need the alligator clips - it just makes it easier).

If the pump whirrs to life, there is something wrong in the circuit feeding it. Fuse you checked, but, you could check to see if there is power going to the hot side of the fuse socket, too. The relay is a likely culprit, but don't rule out faulty wiring somewhere. I know I had LOTS of faulty wiring in my truck (mostly because the PO was, shall we say, someone who should be kept away from tools).

Jason, do the Defenders have an inertia switch? I remember tripping the switch on my RR (under driver seat) after removing the rear carpet ....

Yes there is an inertia switch, it's behind the fuses, there should be a little red button on what looks to be a relay. The fuel pump relay on 94s is next to the ECU, sit in the passenger seat an look down and kick, thats where the relay is, there are 2 down there and they are metal. I agree with Jason, check the wiring it has been known to go bad.

My 94 did the exact same thing right after I bought mine...I think it is just an initiation to owning a defender...Anyways, search for my thread and you will see pictures and also links for where I bought my relay for $10.00 (LR dealer $54.00). I will bet you a coke that it is the relay if it just stop working. Need any other help let me know.

You guy`s are great- thanx for all the help- Can I get at the fuel pump teminal with out dropping the tank.
I think it is on the left side or I mean driver side?
My garage- where my truck is is tiny and my bad boy is dead and you can not get a tow truck back their because it is very narrow- their is like a foot on each side to work and now that she is dead I can not get her up on my ramp can I drop the tank on my d-90 with out lifting her up in ramps or stands. Is their a fuel drain plug in a 94 d-90? I sprayed so much under coating I do not remember.NOW with all that said tomorrow I am going to run a wire and see if my pump comes on.

Steven, on the RR there is a connector by the DS rear wheel (on the frame). Again, I'm not sure if the 90s have the same wiring configuration.

I don't think you would need a ramp to remove the tank, 90s are pretty high .... When I removed my tank on my 88 RR I drained all the fuel (drain plug was on the side of the tank, passenger side).

Newer RRs had an access panel under the carpet in the cargo area, yours might have one also. If it does then you do not need to drop the tank, just remove the access panel and remove the fuel pump.

I have a 91 RR I am parting out so if you need a relay or fuel pump just let me know and I'll stop by and give you a hand.

Good luck.

Hiya John C;
Thank you for your time and I will let you know how it is going.

Definately check the fuel pump relay first. I replaced my fuel pump first and it still didn't start. Turned out the relay was bad. As Mike said, there are two relays next to the ECU on the passenger side of the truck. I think the one for the fuel pump is connected to a blue plug. If you do replace the fuel pump, you shouldn't need the LR tool to turn the ring. I was able to turn mine by hand. If it doesn't turn, use a flathead screwdriver and hammer to get it started. I put the rear of the truck on jack stands to give myself a little extra room underneath, but it is not neccessary. As far as draining the tank, mine was full so I used a bulb pump to remove the fuel. It looks like a rubber hose with a bulb in the middle that you squeeze to pump. Also, I bought one of the $10 relays from Autozone. It started the truck, but drained the battery when left too long. I ended up buying a Bosch relay from AB for about $25.

Atlantic British http://www.roverparts.com/ProductLis...mber=AFU2913OE The cheap relay from AutoZone is an easy way to test and can be used again as a spare if neccessary.

I had the same thing go a few weeks ago, it was the relay.
If you take it to the shop make sure to take your own Barrel or else they'll charge you for that too.


On a side note, they did do it a lot cheaper than I thought it would be.
