connector at fuel tank module, clean and check all grounds off the PCM. Run ground to #2 at tank connector see if gauge reads properly then. Check resistance of #2 terminal at tank connector. You can also do a instrument cluster test by holding down trip reset button and then turning ign to on position, will check for proper operation of gauges.

i cleaned all the contacts you mentioned. should i check the ohms at the sending unit contact 2 at 20 ohms on the multimeter? that instrument cluster test was pretty cool
