Fuel pump relay 2002 Jaguar x-type 2.5

I recently had the same issue and it sounds like it could be fuel related. Have you recently changed the fuel pump or changed the fuel filter? If not there are several other fuel related fuses some in the passenger side fuse box, some in the trunk (which you have found.. but I believe there may be two) and some relays as well. Check all them. If all fuses are okay check to see if your fuel pump is getting power... this can be done by turning your key to the on position and listening under the passenger back seat (this is where your fuel pump is located). You should be able to hear it once you turn your key over to give it power..(now this humming noise will only last for a few seconds so have someone right there while turning the key) if not it is probably the fuel pump....

No FPR fitted.
Works via fuel pump module.
Module powered from fuse 81 on diagram of fascia fuse box. This fuse gets its feed from the ignition relay.

Check fuel pump, fuel pump relay, and also check inertia switch. In ertia switch is usually located inside the cabin on the driverside fire wall on most Ford products.

auto shutoff relay controls both fuel and fire..the parts store can tell you for sure..

If the passkey system were not working the engine should not crank and the fuel injectors would be dead. The security light would also stay on.
The fuel pump relay gets battery voltage and also voltage from the key switch. The computer grounds the relay to power the pump.
The crank sensor does not come into play until the engine is cranking and it supplies a signal for the ignition and injector pulse.
Are you not getting power from the key switch to the relay, or from the battery side to the relay ?

Need to check for fuel and spark
You can crack the fuel line connector at the back of the rail on the drivers side to see if you are getting fuel or have someone listen in the trunk for a humming/buzzing sound when you first turn the ignition on, if you do hear this then the fuel pump is probably working so it would be the crank sensor that has failed. If you have 1/4 or less of a tank of gas, check to make sure you actually have gas as these cars have faulty fuel sendor units which will stick on a 1/4 of a tank.

1) jack-up left front of car (drivers-side)and remove wheel.
2) Remove plastic inner fender .
The maintenance schedule is every 12-thousand miles.

Caution prior to removing fuel filter-
Pull the fuel pump relay or fuse while engine is running, this will disable the electric fuel pump and release fuel pressure in line.

you going to have to narrow it down to see what part is defective. first check make sure you getting sparks by pulling one of the cable and use spare plug and ground it making sure you getting fire when turning engine over. 4 things need to check for fuel delivery. fuse, relay, fuel pump and crank sensor. assumed fuse and relay are good, using 12v light tester locate the fuel pump connectors and connect pos and neg terminal and have someone turn engine over and see is you getting any power to the pump, if the pump is good, crank sensor will be faulty, what crank sensor does it sense the flywheel turning sending info to the ECU then the ECU send power to the fuel pump. keep in mind, fuel pump will only turn on as long the crank sensor sense the flywheel turning.

CHECK YOUR CRANK SENSOR AND CAM SENSOR.
