Thread: Disco 2 - no start

Replace the relay. Sometimes they'll engage but won't handle load.

Sorry, that was re pump. Phone, fat fingers etc....

Ok this is getting odd. Replaced fuel pump. Can hear the new one working. Starts and runs for 3-4 second and then stops. When it stops there is no spark at that point. Re-starts fine and runs for 3-4 seconds and stops - no spark...just keeps repeating.

Does this sound like some BCU-ECU comms problem?

Cheers

Have you replaced the relay?

Most cars will do this prime for a few seconds , and if a signal is not received that the engine is running will turn off the pump.
sorry can answer you question on the ECU-BCU

Thanks gents, replaced relay and whole under bonnet fuse box. Cheers

The pump has plenty of pressure. The BCU has been replaced. The ECU has been replaced...with electronics it could be as simple as a dodgy earth somewhere!!!

Cheers

Does it start every time!
