gas gauge reads 1/8 full when truck is off and reads empty when truck is on
i have a 94 full size bronco and when the truck is off the gas gauge reads 1/8 to 1/4 full when i turn the truck on it reads empty and this happens no matter how much gas is in the truck i tryed to find the ground but could not find it and if it aint the ground will i haft to take the pump out of tank to find the problem
sounds like your sending unit is bad ,yes the tank will have to be droped.
Most likely the sending unit, however swapping in a different fuel gauge may be easiest, next step to troubleshoot.
thank you where is sending unit and you dont think it could be a bad ground
where is ground
where is sending unit and how would gauge be the prob where is the ground so i can check iy
sending unit is in gas tank,ground wire is on top of gas tank,it has to be droped to fix it,if you have never droped a tank DONT try this,it is a very dangrous job.i doubt it is a ground problem,and NO on the gauge,leave that alone,just take it to a mechanic you trust and have him do the job,with a new sending unit it comes with a new float and fuel pump,sock filter.
