Hello all, sorry that this is my first post but I need some help please as I’m stumped.

taken on a project XR4x4 which hasn’t moved (dry stored) since 2004.

I am at the final stages now for MOT however I can’t get the abs pump to run as the two fuses stretched to the purple relays under dash keep blowing.

I have disconnected abs pump, fuse still blows.

I have checked the relay wiring continuity and no issues.

I have also checked the pressure sensor and one wire (brown/white) is showing it has resistance). If you unplug the sensor the fuses won’t blow.

If I bridge the brown & brown/black the fuse still blows.

If I disconnect the ABS ecu the brown/white wire shows no resistance. I snipped the wire at ecu end and the fuses still blow.

I am really stuck here abs not sure now where I should be looking. Can anyone help?

 

If the fuse is blowing, there is clearly a short

Exactly what pressure sensor ?
