I have just bought a '90 xr3i Cab and on the way home it cut out as if there was no fuel. I have been told it is probably the fuel pump relay but I cant find it. Does anybody know where it is located?

angliafrans

it is the purple relay fitted behind the plastic panel on the drivers side footwell (outside)

is it efi ??

cos400

efi dont not have a fuel pump relay if that helps
there have a ecu

easyest way to find it if its mfi is to take the vent out next to the steering wheel shine a torch down the hole and you'll see a row of relays,reach up behind the dash and pull the purple one out.

jimboss

yeah its efi. Checked both the yellow relays and they both work. think the problem may be a bit deeper.

I was told if I took the back seats out I could get to the fuel pump via the inspection panel but this doesnt seem to be the case.
How do I get to the fuel pump so I can test it with a multimeter

xrmalin

if its efi it will be inside the tank.

jimboss

any idea where I will get a pump from. am banging my head off walls no one seems to stock tehm any more

before you try swapping over relays & stuff have you checked thet the fuel cut off switch hasnt popped out ? i had an efi xr3i do it when i hit a large pot hole !!!! just push it to reset it (its in the boot if you dont already know )

jimboss

cheers all for show. I have checked it and it is in. I have checked all relays and they all work. it is defo the pump (i think)

jimboss

I have rpelaced the fuel pump, checked all the relays, bypassed the cutoff switch and still no power to the pump. Wha else could it be. any ideas much appreciated. I have owned it a month now and have only driven it once ing thing!!!!!

ALL4SHOW

does the car turn over & just wont fire up ? if it does have you cleaned the fly wheel sensor ?

jimboss

all 4 show. i havent tried that. surely it cant be something so simple??? where is it locarted? keep the suggestions coming please

Could the fuel filter be blocked? Its on the wing in the enginebay I think.

jimboss

no i have checked the fuel filter thats not blocked

jimboss

can anybody help please? All4show thinks it may be the flywheel sensor but i aint got a clue where it is and how to clean it.
If that doesnt work can I take a feed straight from the battery, put switch on the dash and power the pump that way or does it have to go through the relay?
