I drove the car 2 weeks ago and had a low coolant alarm on a steep downhill, it went away a few minutes later when i leveled out.

Then yesterday the car wouldn't start as the battery was near dead and the car would barely turn over. Put a charger on it last night. This morning the car turns over but will not start. I have code 1111 on my scan.
Tried resetting the car by bringing the negative to the positive terminal. No Help. Checked the fuses in the Trunk and RH Engine compartment all well.

I have put the car back on charge and am hoping for the best.

Any ideas as to the best steps to diagnose?

 

Locate the schrader valve on the fuel injector rail. Crank the engine, then with a rag handy depress the valve with the tip of a small screwdriver and see if you have a strong squirt of fuel. If there is little or no fuel, your fuel pump may have failed.

If you have fuel, then search here for 'cylinder wash' and follow the procedure to add a bit of oil in each cylinder.

 

There was no fuel coming out of the valve at all, checked fuse #7 in trunk no power. Moved relay #1 to relay 4 position. Cranked engine almost started.

Charging battery and will try again.

 

Fuse #7 will not show power unless the engine is running, except for a few seconds while cranking, so this is normal.

I suggest you first have your battery load tested. Alternatively, have someone crank the engine while you read the voltage across the battery with a multimeter. If the battery cannot provide near 12 volts while cranking you should replace it.

If with a known good battery you still have no fuel pressure, your fuel pump is probably done.

 

Battery is close to 12V, Checked the fuel rail again no fuel coming out.

So where is the fuel pump?

 

Fuel pump is in the tank. The tank is between the rear seats and the back of the trunk. On a convertible access is by sliding the tank into the trunk. The hardest part is releasing the two fuel lines under the car. See http://www.jagrepair.com/images/Auto...eplacement.pdf

 

Thank You!
Ordering parts and Fuel Cans, This was the first time I had wished for an empty tank

 

Is there a specific fuel pump brand or recommendation out there?

 

This is cheaper than OEM and generally has gotten good reports: Welsh Enterprises, Inc - Jaguar XK8 / XKR (97-06) Fuel/Emissions Fuel Tank, Fuel Delivery & Return Parts - Fuel Pump

Also, while the pump is out be sure to check electrical continuity through the molded black plastic box in line wth the pump power feed wires inside the tank. This is an electrical noise filter and sometimes fails with the pump due to over-current.

 

Is that a part I should consider replacing anyway, since everything will be apart?
If so I would prefer pre-purchasing prior to this next mechanical adventure starting.

Would you have a part number? and or place to get it

 

Quite a few people have reported no adverse effects by bypassing the electrical filter, so that is an option. I would only caution against it if you listen to AM radio, as you might get some audible interference if the filter is removed.

If you do want to pre-purchase a replacement, you need to buy the fuel pump link lead (Jaguar part number LJC3360AA ): Jaguar Parts - Direct JPLV Porsche Parts.com

 

I appreciate your help, me and my son have a great time working on the car. Although today was in the 60's (F) disapointed for the first time. Glad the car was home!
Would you change the cap?
