Hello guys seeking pointers on as too why she just quit on me .... hard too find reliable information on these cars now a days thursday im going back too the farm too test everything fuel,spark compression (ran fine last year) im having a feeling the fuel pressure is ka puts ? Also the air injection blew a hole in the pipe last year made a nice pop that was when i stored it for winter .

 

Hi - You said that it just quit, does that mean it was running, and just shut off? Is it "trying" to start, or is just turning over? Checking the spark, and the fuel pump is two of the easiest things to check. Lets hope it's just one of them.

 

I'm not clear on the story here, but I'll give it a shot. It was stored for the winter, you brought it out and it refuses to turn over, correct? Maybe the petrol (gas, fuel, etc.) has gone bad after a long winter of sitting there?

Other things to check if it's been sitting at a farm somewhere is for any signs of rodents and chewed-through cables. For being a "Jaguar", these vehicles appear to substantially attract a higher interest from pests. Maybe they just like all the tiny nooks and crannies?

 

Lost track of Time! has spark how do I check for fuel pressure on these cars everything iknow is a** backwards on these. Too answer the big question she was running last year back fired and shut off hasn't started since. I kicked it over on starting fluid but it detonates on it I'm going too clean the fuel filter and go from there hoping theres no damaged although I heard no clanks or clunks when it fires on the startin fluid

 

Do you hear the fuel pump running? Add some premium gas to the tank. Running on old gas is like running on varsol. Replace fuel filter.

 

Pump kicks on no problem ill dump some vp race fuel in iknow it has 5 gallons from last year with marvel mystery in it. Hoe would i check for fuel pressure on these ? Where would i put a guage?

 

You have to "tee" into the existing fuel hose that runs alongside the fuel rail on the left side.

Then, when you're all done, just install a new hose onto the existing pipes.

Doug any way you can point it out? Cant picture it in my head

 

Item #11 here:

Fuel Pressure Regulator-5.3 Litre - Parts For XJS from (V)139052 to (V)179736 | Jaguar Heritage Parts UK


It's combination metal/rubber fuel line. Cut the rubber section, "tee" in your pressure gauge

Cheers

Thanks doug! Very appreciated i was looking too drop on a set of guages under there. Heres another question ....how do we go aftermarket on the fuel rail? Id like too delete the fire causing set up

 

I'm not aware of any.

Change fuel hoses every 5-7 years or so and you won't have any fires

Cheers

Ahh okay i have come across a few who have this with great results ill quiz them ! Many thanks doug

 

I don't have a picture handy, but have incorporated a very small fuel gauge in line, exactly where Doug mentions. I plan on leaving it. I bout it on eBay, for about 20 bucks, and then bought the fittings at a local auto parts store. I can check the operation of my regulators very simply. I can even see if the hot fuel rail valve is working properly.

 

How much of a pain in the a** was it ? Havent done a softline install . I have done it on hardlines but thats it

 

Very, very easy. Its just a brass T, with two 1/8" pipe thread, the gauge, and two 1/8" X 5/16 inch barb fittings. It almost looks like it should be there. Jaguar didn't even incorporate a way to check fuel pressure, and inquiring minds want to know, so......

Anyway, my car has about 30psi running. With the regulators working properly, the fuel pressure increases to 35-36psi when it is revved.

 

Sorry, a T with three 1/8" female threaded ports.

 

And two clamps, lol. I'm like Doug, replace the lines every 5 years, and there will be no fires. But take the air filter housings off, start at the incoming fuel line, and replace every single one of them. Not just the ones up top. It will take a while the first time, as you have to cut the ferrels off carefully, but use proper fuel hose clamps going back.
