Oil Pressure Light/Fuel Pump

Post by WUFFIAT78 »

Merry Christmas all...

I recently replaced all the bulbs in the instrument panel with LED (not the alternator bulb). After doing this work my fuel pump no longer is receiving power to the relay to engage the fuel pump. The relay is receiving its voltage from a gray/orange wire near the alternator. I have read a few posts about the oil pressure light should be on when the ignition is in the "start" position. I am highly suspicious that the change of the bulbs is related to the fuel pump no longer work.

Thoughts?

Some LED are polarized. So check if you have positive at the base of the bulb.
