jack Posted January 4, 2009 Report Share Posted January 4, 2009 vehical=1985 GMC 1/2T with dual saddle tanks symtoms...oct everything fine parked for a few months during build topped off both tanks and drove for a week......now the problem starts. press switch to change from rt to lft tank and the fuel guage still says empty so either it is not switching or both tanks low??? refill rt tank...hit switch to lft tank and now it indicates that it is same level as rt...again, so i am assuming it is not switching. next problem...i remove switch(center of dash) to make sure it is firmly plugged in. unplug use meter to check continuity (to make sure that the switch does something when i press it between positions). plug it back in. turn on ignition and now the gauge reads about 4oclock......full line is at 1oclock and it is not dropping at all after 2days of commute. please help with what to check and how to check it Quote http://www.stevemeadedesigns.com/board/ind...showtopic=29213 "sleeper build" (1) DC AUDIO Level4XL 10 (2) PowermasterD2700 batteries ALL FOR SALE TEAM DC AUDIO TEAM DIRTFLOORPOOR Link to comment Share on other sites More sharing options...
Andrew2944r Posted January 4, 2009 Report Share Posted January 4, 2009 (edited) I know the 80 model's were notorious for sticking floats, other than that I dunno Edited January 4, 2009 by Andrew2944r Quote Team Ampere Audio Link to comment Share on other sites More sharing options...
Forevrbumpn Posted January 4, 2009 Report Share Posted January 4, 2009 get a few people and shake that back end really hard- if its possible the floats are sticking Quote I have a ritual called "terminator". I crouch in the shower in the "naked terminator" pose. With eyes closed I crouch for a minute and visualize either Arnie or the guy from the 2nd movie. I then start to hum the T2 theme. Slowly I rise to a standing position and open my eyes. It helps me get through my day. The only problem is if the shower curtain sticks to my terminator leg. It sorta ruins the fantasy.

jack Posted January 4, 2009 Author Report Share Posted January 4, 2009 removed guage and checked it for function, it seems that i am not getting ground reference but like i stated all i did was remove the switch and re install. it is not on the same circuit as the indicator so????

Aaron813 Posted January 4, 2009 Report Share Posted January 4, 2009 Jack im having the same problem with my 2000 Silverado 1/2 ton my mechanic told me it was a sensor in my tank the gauge will work sometimes but when I top the tank off it doesnt work I have to wait a few days before it will read how much gas I really do have Quote Link to comment Share on other sites More sharing options...
capalass23 Posted January 4, 2009 Report Share Posted January 4, 2009 ^^^ the 2000 chevy pick ups are known for that problem and the sensor does fix the problem but i the 80s i would try a new fuel guage Quote 95 WAGON BUILD FEED BACK Link to comment Share on other sites More sharing options...
jack Posted January 4, 2009 Author Report Share Posted January 4, 2009 ^^^ the 2000 chevy pick ups are known for that problem and the sensor does fix the problem but i the 80s i would try a new fuel guagenot the gauge...like i said the fgauge was reading accurate until a unplugged the tank selector switch and the plugged it back in. the initial problem was i did not think the tanks were switching, ie...right tank empty (as indicated by funtioning gauge) switch to full left tank,(still shows empty) fill right tank(gauge shows proper level) switch to left tank gauge does not move from full. remove switch reinstall now it rests all the way out of wack. not to be an asshole but please unless you absolutely know what you are talking about please dont speculate especialy when i have been clear of the tests and symptoms i have encountered Quote http://www.stevemeadedesigns.com/board/ind...showtopic=29213 "sleeper build" (1) DC AUDIO Level4XL 10 (2) PowermasterD2700 batteries ALL FOR SALE TEAM DC AUDIO TEAM DIRTFLOORPOOR Link to comment Share on other sites More sharing options...
capalass23 Posted January 4, 2009 Report Share Posted January 4, 2009 is the switch bad? Quote 95 WAGON BUILD FEED BACK Link to comment Share on other sites More sharing options...
jack Posted January 4, 2009 Author Report Share Posted January 4, 2009 is the switch bad?no it is a 2 way momentary that swiches polarity (to the selector valve is my guess) there is a pink and black wire at the switch (grd and ign) and a lt gr and a dk grn greens switch polarity depending on switch posistion. probably controls an actuator in the selector valve i have not tested the wires at the vavle yet to see if there is loss in signal yet.
