| Yep all clear.
If the harness is a possible issue I was considering this.
The pump has a 12v feed when the ignition is turned on. The ECU then turns the earth on until the pump is up to pressure then turns it off. When the ECU gets a signal from the ignition sensor it turns the earth on again so the engine will run. So if I run a seperate fused/switched live from the battery to the pump and a seperate earth from the pump to the corresponding pin on ECU this in my mind would eliminate any of the existing wiring and possible problem? |
