I have a 1999 TD5 defender with a pump problem.
When the ignition is turned on, the fuel pump relay does not energise. Then I manually close the fuel pump relay the pump starts. So the fuel pumps works correctly. I get 12v on pin 86 of the relay when the ignition is on. (between chassis and pin contact and between pins 85 and 86). I have checked continuity between the relay pin 85 and the ECU connector, the blue and purple wire. The main relay and inertia switch are ok. If I short out the relay to start the pump the engine still won't start. Am I looking at a new ECU or can there be another problem.
