You are dealing with a intermittent fuel pump problem can be the pump itself or bad connections. Here is the main concern for the fuel pump to turn on the ECM must recieve a RPM signal from the crank position sensor this signal must be recieved at the ECM greater than 250 RPM if it is not the fuel pump will not turn on. The use of a labscope works here or a generic scan tool with live data will show this. This problem necessarily gives engine codes.

SOURCE: can't find fuel filter

The fuel filter is located above the rear axle on the driver's side. The easiest way to replace it is to break the fuel line nut loose on the side nearest the wheel and screw it all the way off (you may have a small amount of gasoline come out of the filter, so have a container handy). Then break the fuel line nut loose on the inlet side (farthest away from the wheel well) by using your wrench to turn the entire fuel filter using the nut that is part of the filter on the side nearest the wheel well. Reinstalling the filter is just the reverse of this procedure. Be sure to check that the O-rings inside the nuts are good and don't overtighten the filter or you might cut the O-rings and the filter connections will leak

SOURCE: 1998 jaguar xj8 consumes anti-freeze

First thing to check is the radiator cap seal. If it is not sealing properly, the water will boil off and then soon, the anti freeze will begin to disappear. Clean the metal surfaces and gasket and make sure it is tight ---or buy a new cap --but make sure there is a seal. If that doesn't cure it, you may have a head gasket leak that blows the coolant (anti freeze) into one cylinder. If that cylinder is tight, the coolant will only evaporate in the heat and be blown out the exhaust --not entering the oil pan. Check your exhaust when you start up. You may see white smoke, or even liquid, exiting the exhaust pipe, indicating a blown head gasket (then engine may run rough, too). If this is the case, there are reasonably inexpensive cures for this in some cases.

My xj8 Jaguar crank up and sets right back off what all could be wrong


Security is set. Could be one problem. Fuel system can do this, but rarely. Takes a scanner to see where to look first.

Check fuel pressure at the fuel rail. Go to OReilly's and rent a fuel pressure gauge. There is a port on the fuel rail that you will be able to hook the gauge to. Turn your key forward and the fuel pump pressurizes the fuel system. While you are at the parts store ask them what the fuel pressure should be and compare with your results.

Jaguar xj8 1998 starting problems


sounds like you may have a clog in the fuel delivery system...Have you changed your fuel filter? If so,check the fuel pump pressure by getting a tester from Harbor Freight...connect to the chafer valve on the fuel rail...If the fuel pressuee is correct,and the filter has been changed please have the dealership do a pressurized intake cleaning.(3m product).It isnt that much to do but will make a great difference in the cars ability to start and the response will be much greater.

I ran out of gas and after fueling the car it still wont start dont think its getting any gas. the car is a 2001 jaguar xj8. How or where can i check fuel system?


if you ran completely out of gas you may have harmed the fuel pump,the gas is what keeps the fuel pump bearings lubricated.there is one thing you can try that has work alot of times in my line of work,the pump could just be stuck and you have one chance to get it going again,have a friend try to start your car while you hit the bottom of the fuel tank with a hammer,sometimes this vibration will unlodge the pump

they are pressed in, Jaguar uses a special tool which fits over the bushing and you have to use a press to remove them, sometimes they are so tight they need to be burped out with an air hammer.
Not a job I would tackle myself as you need to strip down the suspension to get the arm off for replacement.

Yes it does have a cut switch, located on the fire wall in the engine compactment. If you push the black button it will reset it. I don't think it's that . I think you should check the fuse, if good you should leave the key in on position or the # 2 position for 5 minutes so the fuel pump can prime the line.


Good luck
