I checked grounds at motor, and frame near fuel sending unit. I did a continuity test from purple/white wire at sending unit to pcm at pin 54 then a continuity test from pin 38 purple wire to gauge.
When off I’m getting 124ohms from sending unit at pcm then 36ohms from gauge at pcm When running im getting 1.5v from sending unit at pcm then 9volts from gauge at pcm and if I put them together and bypass the pcm it reads 28ohms off and 9volts running all sequences still show full when pcm bypassed it dances around a little bit but still on full. And if I ground the wire going to gauge it goes to empty
