Fuel pump not working

WHAT MEANS FILER (FUEL FILLER CAP)? 33 years old.
ever see car run right in the last decade/( or?)_
OR TYPO FUEL FILTER.????????
gas engine? petrol? or what engine is there? 4.0L ?
okay i answer for filter hose (conn) pulled
well the electric pump only runs key on cranking(or running)

you never once told the story why you are here, dead engine?
no symptoms told at all, engine dead or stalls or engine weak or misfires.
engine dead:???????

1. engine pass compression test over 150PSI? on all/? 33yo !
2. spark good on all cylinders
3. now we test fuel not first. for sure relic cars like this. 300k miles on it?

the spare parts store tells me

2 Fuel Pumps may be Required - 1 Externally Mounted & 1 Mounted In Tank

learn this too, pump count. no just in the tank.
the external pump if fitted looks like this
seen connected to lines easy to see it; if there.



check it cranking
and 1990 car are hard to diagnose (no OBD2 yet)
most do have ECM and does flash codes. on demand.
covered in the manual
6 injectors to fail or the ECM does not want to fire them for many reasons, ask./
old old spark distributor bad cap/rotor 'wires sets and plugs .

Remove as much fuel from tank using a syphon or plastic pump.
Remove tank from car, Tip it upside down to drain remaining fuel.
DO NOT WELD the tank if it is leaking or the remaining fuel fumes will explode.

The best way is to take the tank out completely to clean , as you have to make sure that it is 100% clean so that the problem is solved completely.
If not cleaned properly it will make you a lot of problems

Check the fuel pressure, the electric in tank fuel pump may be sticking.

open boot take spare wheel out then there is either two or four screws on wheel surrond in boot when you take cover of you will see pump

hello, my name is thedon052001 and i just pruchased the 1993 jaguar xj6 and there are some problems to it, the main problem is that the security system needs to be reset or taking out and i need an exhaust system and fuel pump what is the best thing for me to do

Fuel pump is bad or plugged fuel filter it seems. Crack the line from the filter leading towards the engine first. If gas starts squirting out fast, you have good pressue. If not the filter is plugged or a bad pump. How old is the fuel filter by chance? If original its plugged up by now

Hi irvj6ohn:
The 1993 and 1994 XJ6 Fuel Pump Relay is located in the trunk of the vehicle on the right hand rear side. It is light blue and black in color.
I hope this helps.
