AWSpoofwil Posted April 15, 2013 Report Share Posted April 15, 2013 Fuel gauge stopped working in the 620.. this wouldn't be a problem usually, but the odometer don't work either.. thought on how to fix the fuel gauge? I just filled it all the way up this mornin and it says I only have less than a half tank.. Quote Link to comment
Radiant-Designer Posted April 15, 2013 Report Share Posted April 15, 2013 it always reads a little less than half, or when full it reads a lil less than half and it goes down from there? Quote Link to comment
Radiant-Designer Posted April 15, 2013 Report Share Posted April 15, 2013 and does the odometer not work becuase the speedo doesnt work or another issue? Quote Link to comment
Eagle_Adam Posted April 15, 2013 Report Share Posted April 15, 2013 he's KA swapped his truck and it sounds like a few details are still in need of being wrapped up Quote Link to comment
Radiant-Designer Posted April 15, 2013 Report Share Posted April 15, 2013 well it seems like a lot of details are missing that would be needed to correctly diagnose and correct this... Quote Link to comment
izzo Posted April 15, 2013 Report Share Posted April 15, 2013 Yeah. we need details son. Stock fuel gauge? Stock speedo? Or aftermarket? Its a bitch on the 620s, but reach up in there and wiggle the connectors on the sending unit, if you can. see if they just came off or what not... To bad there wasn't easier access, you could just ground the sending unit wire out and see if it reads full... If so it'd be the sending unit. Quote Link to comment
datzenmike Posted April 15, 2013 Report Share Posted April 15, 2013 The temp and fuel gauge run off the same volt regulator, so if the temp is also not working then this is the problem. If temp gauge is working.... Key on and ground the Yellow sender wire at the tank... gauge should read full. If it does then the sender in the tank is stuck OR the Black ground wire and/or tank isn't properly grounded. If gauge continues to not work, pull the 10 pin plug under the passenger seat and ground the Yellow wire on the dash side harness. Gauge reads full... the wire to the tank is broken Gauge doesn't read... well running out of options here. The round black plastic plug in the back of the gauge cluster may be loose. You could try unplugging it and plugging it in to clean the contacts, last is the gauge may be bad. Sometimes just taking things out and putting them back makes them work. Quote Link to comment
