Jaguar xj sport 3.2 no spark or injector pulse

yes. Needs both crank and cam signals to fire injectors and ign

does it have spark ?
No Start No injector pulse shorted injector part 1

If you watch any of these ,watch the last one .Ignition control module can cause no injector pulse but still have spark

Spark, fuel and compression . Do you have spark at the plugs ? If not, does the tachometer register while cranking the engine over ? Fuel pressure and injector pulse signals need verification . Compression needs checking .

Hi Fred:
I;d be checking the cps.

If you have spark at all the plugs, the crank sensor should be ok. You should use a gage to check fuel pressure? I don't know engine size? For the 3.1L engine, my info says 40--46 psi.
It is possible to have spark at the plugs, but, the computer doesn't see rpm signal. If that is the case, no fuel injector pulse. The purple wire with white tracer carries rpm signal from ignition module to pcm, that wire has dc pulse, engine cranking. If nothing there, have to check ignition module.
How long since a tune-up? Any applicable trouble codes?

The first thing to check would be spark. This can be done by connecting a spark plug tester to a plug wire while the engine is cranking. The tester must be grounded to the engine block for a good electrical connection.. Your fuel pump pressure is OK.
The problem should be electrical so check
1. No voltage to the fuel injectors (blown injector fuse or bad relay)
2. No pulse signal to the injectors from the PCM (no crank or cam sensor input to the PCM, or a bad driver circuit in the PCM, or a wiring harness problem)
3. A shorted fuel injector (robs voltage from the other injectors so none will operate)

There is no simple answer, there are to many variables. If you have access to a scan tool, pulling the codes should help. Without them its back to old school hunt and peck method. At this point we need to narrow down the problem. You need to test for spark.

1. Tag and disconnect the spark plug wires from the spark plugs.
   
2. Remove the spark plugs and install the spark plug wires to each spark plug.
   
3. Ground (do not hold spark plug) the spark plug; check if spark occurs while engine is being cranked.
   

Crank the engine for no more than 2 seconds at a time to prevent flooding the engine with gasoline.
If you have spark, You will want to make sure you have fuel injector pulse, along with fuel pressure. If you have spark ..simply spray some starting fluid in through the air filter and hold the gas pedal to the floor and crank it over while spraying. If it fires up, you know it is fuel related( fuel pump, regulator, or ECM if no injector pulse) . If you have no spark then look at ignition coil connection and trace through to the distributor( if equipped ). The crank shaft sensor has a tendency to fail on these as well. This should give you a few things to test and check to start you on your way to narrowing it down. If you have no spark then look at ignition coil connection for power and trace through to the distributor( if equipped ). If it is DIS( no distributor). It may be the Crank sensor or the ECU. The crank shaft sensor has a tendency to fail on these as well.
The ECU uses the signal sent from the Crank sensor to trigger the spark and fuel injectors. ( make certain you have checked all fuses)

might be wise to check the fuel pressure

you need to see if you have spark and check all fuses and see if you have fuel pressure and injector pulse if no spark and no injector pulse suspect crank sensor or ignition control module if no fuel pressure check fuses then relays and then suspect pump

check crank sensor or check fuses ALL fuses
