A few electrical questions ,
The oil pressure gauge is always showing max pressure, but by disconnecting the sensor wire it drops back ,
Checked the resistance of the sensor 250 ohms at rest and decreases by applying compressed air to 5 ohms, so I would think the sensor is ok , got a good feed and earth at the gauge ,any ideas ?.
I do not have a trigger at the fuel pump relay (green /white wire)
does it switch pos or neg ?
I think this comes direct from the ECU , is the fuel pump relay feed as soon as the ign is on or is only when the ECU sees a crank signal ?
Also have a good feed to the injectors but when cranking the is no neg pulse .
Any help would be greatly received.
