I han an 06 1500 4x4 Laramie 5.7 hemi. The fuel pump went out a while back and I had it replaced, everything went well then about a minute later it threw a code and the fuel gauge stopped working. Mechanic scanned it and it said sending unit. Replaced with another and the gauge still doesn't work. Once again it was replaced with an oem one this time and same result. Fuel gauge has not worked since the initial replacement. Gauge check shows it only goes to full, half and empty it doesn't go to 3/4 or 1/4. Anyone have any info they can provide on this? I repaired my tach this morning hoping it might help but it didn't.
