Jaguar Repair Problems? Ask a Jaguar Repairs Expert.
We may have a problem with the transmission rotory switch on the transmission as this signals the ECM that the transmission is in park or neutral and the ECM will then energize the injectors and coils. See if the engine will start in neutral. We then should use an OBD II scan tool to read fault codes. Let me know.
Sorry for the delay. If we are sure we have no spark please check for injector pulse when cranking. Then make sure we have power to the coils on the pink/white wires as the coils should have battery voltage with the ignition ON.
Ok no power to the coils is definitely a problem. If we do not have power to the pink/white wires with the ignition ON then we need to check the ignition coil relay and the fuses. The fuses you need to check for power on are fuse #14 and #18 both 10 amp in the small engine management fuse box in the engine compartment and the relay is located under the ECM enclosure in the passenger rear of the engine compartment. Click on the link. Visually inspect the fuses then make sure voltage is present to both sides of the fuse with the ignition ON.
The pink/white wire at the coils definitely shows no voltage with the ignition on.?
Go to the ignition coil relay. The relays may not be in the correct order so we will need to go by the wiring color. With the ignition on we should have power on the white/pink, brown/white and the pink/white.
Could be. Disconnect the negative battery terminal cable for about an hour. Put a charger on the battery just in case it is a voltage issue. Reconnect the battery and lock/unlock the driver door using the key in the lock cylinder. Also please confirm with a digital multimeter that power on the ignition coil connector.
Try holding your foot to the floor again and we should also again try spraying some cleaner into the air intake while an assistant cranks the engine.
I think the problem may be either the security or possibly the transmission rotory switch as that will cause no ignition and injector pulse. We do need to make sure power is present at the coils. Try moving the shifter back and forth to see if it will start.
It would actually be the mobilization of the ECM which would need to be reset with the Jag factory tool. We should start from scratch. Double check for spark, fuel pressure and injector pulse ti see what is missing. Also with a compatible OBD II tool read all the faults codes if any and clear them.
