The inertia switch is a spring loaded so if you knock on the switch lightly with a screwdriver handle it should pop and make a click ,
then when you press it in should also make a click and stay in the down position .
Then on the connector you should have power on one of the wires 12+volts .with the switch in the OFF position (UP)
and power on both with the switch on (down position).
Check this out then get back to me .
If not sure pull the wiring connector and jump the wires and try and start .
Let me know what happens .
Okay so before you jumped the switch there was no fuel pump working .
Thank you for the detailed information .
You said you called out LR of Dallas and they said it was the fuel pump ,so i thought that
they would of also done a diagnostic scan of the management system ??
So was helping you in finding out why the pump is not working and now found it was the inertia switch .
these do fail .
Anyway we have to do a diagnostic scan of the system and check for malfunction codes ..
Can you do this ..
Kind regards Greg
Lifter when you have the engine running .
this can be sorted out with a engine flush and new engine oil
that i can explain how to do this when you arev ready ,don;t buy anyparts
Check battery voltage you need 12.4 plus or the relays may start clicking if the battery is low on charge .
First a diagnostic scan .
And with you now enjoying the work on this vehicle invest in a good scan tool you can get a good one from 50 - 250
less than going to LR .
Scan tool This one is 99 pounds .
Okay go into data stream and get me the readings, at idle and again at
2000 rpm .
Nice tool working okay .
But not all systems have completed 5 of them .
Need to do a longer test drive though town and down the highway at 50mph for at least 5 minutes at this speed .
When cranking the engine spray ether down the throttle body at the same time and let me know if she now starts up .
Just go though the scan tool and clear all codes even if there are none.
Hi remove the hose as shown in the diagram .
Here you spray down the TB when cranking , if she fires up and dies then we know we have ignition system working and the problem is fuel delivery ..
Okay we do have spark ,
have one sit in the car and press slightly the throttle when at the same time the engine is cranking spray down the throttle body .
If she wants to start and fires up and spits and coughs then we do have a sparking engine and a problem with the fuel .
Please do a compression test and check the colurs of the spark plugs .
