if you have a engine light on then by far the fastest way forward is to plug in a scan tool to read off the stored fault code - thi swill point directly to the fault and greatly speed up repair

I'd check that you're getting full power to the glow-plugs, they pull a lot of current so take care when checking but see if the relay is clicking when the ignition is turned on first and also check the fuse if this is OK check to see if the engine earth strap is also OK.

If the plugs haven't been changed in the last 20K then they may have to be replaced.

You can test the glow-plugs with a multimeter by measuring the resistance across the plug ( between the power connection and the body) it should be around 4-8ohms if its tending to infinity / open circuit the plug is faulty or by using a clip on current clamp, either on the supply wire to glow plugs or onto engine earth, with glow plug light on you should see 15-20amps for each glow plug fitted, 4 cylinders would be approximately 60-80amps.

Also its worth checking that the electric pump that feeds the main fuel pump is working correctly, it should run for a few seconds then switch off when you first turn the ignition on. If the connections to this are corroded or damaged then the pump could stop at any time. Check that its relay switches in and out and the relay contacts are clean and bright – replace the relay if in any doubt and do the same for the fuse, ideally measure the voltage at the pump and check its getting 12V

We have scan the engine it only gives us a faulty camshaft sensor which we replaced that Car Could Only Start with easy Start spray fuel pump is working the original getting through we checked all fuses and everything else it's been moved from one mechanic to another with no luck so far is there any other fuel filter on a Jaguar 2.0 diesel is there two fuel filters or just the one

just the one filter, so if you have a pressure gauge you can hook up then that would be ideal to confirm that there's 3 bar at the main pump

Could also be an injector leaking fuel back through the overspill pipe, so not getting enough fuel pressure to tell ECU to fire the injectors, this is trickier to find and you’ll need the garage to do a ‘run back’ test to identify which one is the issue
