Default Fuel Level Sensor problems \ troubleshooting

My problem was unique but I feel there is some value in what i found. and maybe somebody searching will find this useful.

Maybe with google because this forum's search engine doesn't work like other vbulletin's

the factory service manual was very helpful.

the level sensor goes strait to the guage, dark blue wire pin 9 in the left plug behind the guage. the ground for the sensor goes all the way up to the front passenger fender next to the top motor mount.

The level sensor reads 70 ohms at empty and ~1000 ohms at full.

at startup my guage would go to full then strait down to empty, the ground was bad at the passenger fender. This is also where the fuel pump is grounded.

taking the tank out isn't horrible but sucks when it isn't needed.
