Hi I just bought a 1992 range rover classic that has some problems.. I am trying to diagnose the reason that the truck wont start this is what ive done..

checked the relays both the fuel pump and the main relay for the efi both work fine and when the key is turned on cna hear clicking
replaced the fuel pump
pulled the fuel pump out and tested it on the bench.. works fine
tested the plug that plugs into the fuel pump and am getting 12 volts..
checked the inertia switch and that is fine..
so im not sure what else to check..

when I check the fuses under the passengers seat the 20Amp main efi fuse is blown and is blowing as soon as i turn the key on...
also i was told that with a range rover if there is an electrical issue on a range rover the parking lights stay on.. cause they are on..

on wednesday i am going to pull down the headliner in the rear of the truck and check the fuel pump ground as i saw thats where its located on allsat.. any other ideas what it could be??

Thanks all
A1C Hutchins

it cranks awesome.. if i put either down the intake it fires up and runs awesome.. im not getting any power to the fuel pump.. could the ground under the headliner in the rear that controls the fuel pump could that blow the EFI fuse also think that could be why the lights stay on?

As indicated by others, the fuel pump will only run for a few seconds with the motor not running. You can check that fuel is getting to the fuel rail by either disconnecting the return hose and seeing fuel run out when you first switch the ignition on or by pushing in the thing that looks like a tyre valve on the rail.

To get fuel into the engine the injectors have to be working. These are controlled by the EFI ECU. If your fuse is blown it is unlikely that the ECU is operating and therefore the engine is not getting any fuel even though the fuel pump may be working fine.

You need to fix the fuse problem to your ECU. Check your wiring to make sure that a wire is not shorting out somewhere.
