New to the SVO here. My 84 2.3T has no voltage to the fuel pumps. The relay under the driver's seat is not switching on. If I manually ground the relay ground wire it will activate and send power to the under chassis pump but the tank pump shows a "low voltage pulsing" via test light to the ground wire.
The in tank pump has been replaced. With the under chassis pump running I still get very little fuel pressure to the fuel rail.
Any suggestions from the masters here?
