88 xjs 5.3 v12 not getting fuel?
Well I did get around too running over my cat with a multi meter I do have power at the coil it is getting a serious spark (ask me how iknow) she's fires on starting fluid no gas in the tank currently but I believe someone siphoned some fuel when it was stored. What can shut off fuel on these cars? Im in the process of getting a noid light too check if the inhectors are firing it did sit for several years so I'm debating running marvel threw the injectors and manually pulsing them. Any thoughts ?

I have an '88 too and this worked for me. If your fuel pump is working here's what to do next. Turn the key to "run". Have a helper put their ear right up against the injector rail. Fully depress the gas pedal and release. The helper should here all the injectors click once.
If they don't click I'd say the ECU is suspect. If they do and you're sure it's a fueling problem, I'd be suspect of the fuel pressure.
Good luck!

Also, if you have not done so yet, undo the fuel pipe in the engine bay RHS before it goes into the regulator, poke the end into a plastic bottle and ask a friend to switch on the ignition. You should have a 2 second burst of high pressure fuel. If not, or not HP, you know something in the supply system is not working.

What Greg said was a good starting point before you go pulling the aux tank. Although this is a must as it will be full of crud unless it has been cleaned.

Swirl tank - you need to remove the battery and mount. Either drain the tank or clamp off the swirl tank feed, remove the output hose and unbolt the tank.
There is a circular disk in the front top with the hoses this undoes and you can gain access.
Here are some pics. The plastic container is what came out of my swirl tank, and mine was clean.

Firstly, Welcome to the Forums.
When time permits, please do an Intro in the New Members Area.
That leak is the rubber hose in the fuel supply line TO the engine bay.
Remove the wheel. look up on the inner face of the chassis rail, near the rear cradle, and you will see the steel pipe with the hose.
Access is testy, but doable.
Use quality EFI hose and EFI clamps, CAREFULLY cut the old hose away, and slide in the new.
This is the SUPPLY side, so HIGH pressure.
There is also one on the other side, which is the RETURN, and LO pressure.
If it were my car I would do both, and then venture to the engine bay and replaece ALL the fuel hoses in there. AGE is now against these components.

Hello Singb
Fuel line goes from the little surge tank, through the filter and fuel pump and attaches to the bulk head just behind the rear wheel arch. Connection both side of this bulk head is by steel pipe. It then has a small section of rubber hose that connects the bulk head steel pipe to the steel pipe that goes over the rear suspension frame. Sounds like this rubber hose has failed.
This is a very difficult (at least I thought so) piece of hose to replace. Easy enough to see with the rear tire removed though
This is in my 1980 - no idea what model yours is, and things did change through the years
Cheers

Hello Singb again
Added on to Grants comments on the return line (left hand side) - mine has two sections of rubber hose. 1st one just in front of the suspension, and the other just behind. Also not the best access.
These run pretty close to the exhaust pipes, so if in doubt - please change them out
Cheers

XJS Fuel leak
Thank you Grant Francis and Steve
I wasn't expecting a quick response and truly appreciate your advice. It looks like I found a good community on this site.
Thanks for the tip on removing the tire. I will get to this project sometime around Christmas.
Here is a video that shows the leak.

Hi Singhb
OMG!
You are going to burn your House down!
Just one Spark and you will never put it out!
Have a look in the Boot/Trunk and see if you can see anything obvious like a leaking rubber tube or something and have a dry powder Fire Extinguisher with you just in case!
That has to be the worst leak that I have ever seen, so don't attempt to Start it until you know what's wrong and have fixed it, or you will be Toast!

Hello Singb
As explained above - just above that bulkhead is a small rubber hose - about 100mm in length - I will find my photo when I am home and post it, but it is very obvious when you remove the tire.
Also - get into your boot and really twist those rubber hoses from the surge tank to the bulk head. If they make noise or are brittle, or look suspicious, then please consider changing them out.
That is no leak - that is a flood. Just to reinforce what OB has said - I once purchased a Dodge Pheonix that had a fuel fire start at the petrol tank - They got the fire out at the front door hinge. (I purchased it for the block under the bonnet).
Please don't let this happen to yours
Cheers
