Jaguar Repair Problems? Ask a Jaguar Repairs Expert.
Usually the inertia switch will prevent the engine from cranking but yes we should check to make sure it has not tripped. We still may have a problem with the ECM.
I recommend we check battery voltage at all the fuses in the engine compartment fuse box with the ignition on again. The reason why we are checking for voltage is this will also check the system power relays and diodes. Unfortunately there is programming needed if a new or used ECM is installed.
Let me double check the diagram when I get back into the shop.
Throttle should buzz. PLease doubl check that F18 in the front fuse box. If it is ok then maybe in the process of flexing the harness to remove the intake we have some damaged wires at the ECM connector.
The inertia switch controls more than just the fuel pump so I don't think that is the problem. Let me know.
