I don't have a diagram but I can tell you the pink wire going into the tank should be the sending unit for the gauge.

Hello
This problem is caused by a defective fuel gage sending unit, the sending unit is located inside the fuel tank and is part of the fuel pump module but is sold separately in a kit from ACDelco, to replace the fuel gage sending unit requires the fuel tank be removed from the car. Below is a price and part number courtesy of rockauto.com

SOURCE: fuel pump wiring diagram 1988 chevy truck

I personally have 1988 GMC truck and had to replace the fuel pump. I found all the info including wiring diagram in a haynes repair manual. These can be purchased in most automotive parts stores. Something I found interesting is that the fuel pump's operation works through the oil pressure switch, located by the distributor screwed into the engine block. If this switch is stuck or sticking it will affect the fuel pump. Replaced a good fuel pump for nothing! The truck had sit up for awhile and the ground wire connections had to be cleaned as well.

SOURCE: 2002 Chevy Suburban: Fuel gauge reads empty, tank is half full

Youre gauge is controlled by a plunger in the fuel tank which is attached to the sensor and the fuel gauge. it sounds like when the plunger goes down half way its either getting stuck down lower then it should. Needs replacing. Any mechanic can do this install for you.

Fairly common problem with GM vehicles. The sending unit in your tank has a small circuit board that an arm is attached to which moves up and down according to your fuel level. This circuit board and arm are not making good contact. Unfortunately the only good solution is to replace this part.

SOURCE: The gas gauge on my 2002 chevy venture is not

Hi:
Your tank sending unit is bad. Unfortunately, it is part of the fuel pump assembly, and the part costs around $400, give or take. plus installation labor. It is an all too common problem on GM vehicles, as I have had to change it on my last 2 GMs. If you do an internet search you will find plenty of others in the same boat!

1987 Nissan Maximum gas hand doesn't work & transmission is reading full but it leaks sometimes


There are three fixes possible for the gas gauge....but I would have this troubleshot by a garage:

1. The gas gauge itself does not work anymore. It could have just finally "died". Problem is, you cannot replace just the gauge. It has to be the whole instrument cluster. Having a garage shoot power TO the gauge and then shot the gauge itself will let you know if the gauge assembly is bad.

2. The fuel sending unit is bad. This means the wiring to the gas tank fuel pump/sending unit is bad and does not work. The signal is not being sent to the fuel/gas gauge. This means the fuel pump assembly needs replacing.

3. There is a wire problem somewhere between the gas tank and the dash to the fuel gauge.

The transmission leaking but still reading full just means that there is plenty of transmission fluid in the transmission. The drips or spots you are finding are not enough to "read" low enough. Unless you have a HUGE spot of tranny fluid left on the ground, I would just think about a transmission fluid filter change. This way, a new pan gasket will be installed and fresh fluid filled to the proper level will be accomplished on your car.

How many wires are running from the float from gas tank, I only see one . my fuel Gage reads empty but when I unplug the wire it reads full then when I plug it in it reads empty again what do I look for


I think by what you have decribed is the gauge in the dash itself is bad. When the wire is unpluged the gauge should read empty. I assume that this is an older Chevy with a mechanical fuel pump being there is only one wire. You can also check to see if the sending unit in the tank is operating properly but reading the ohmn's thru the wire.

check the spark plug gaps and make sure their set to 25th ,do this first then if still not starting then look at the autochoke ,this is an old vehicle and so it should have a sensor that turns the autochoke on like a temperature sensor in the head for the gauge but iam not familar with this american vehicle to be able to tell you sorry

Put new fuel pump, fuse, and relay in 1998 chevy s10 and still no power to fuel pump


Did you check the ground wire on the frame. There is a ground wire that is bolted to the top frame rail near the left rear wheel opening. I've seen that wire break or get corroded where it bolts to the frame. I'm not sure of the location on a 1998 but that's where it is on the earlier models as well as the full size trucks. That wire also grounds the gas gauge, does the gas gauge read goofy? Also keep in mind the pump only runs for 3-5 seconds then it shut off, until the engine starts, or the starter is engaged. Good luck!

Our Chevy 1989 S-10 seems to run good until we put it in gear, and try to drive. For awhile it was doing fine as long as we put a little pressure on the gearshift so it was at the top most part of drive....


I think the firstr thing you should do is check for loose ground wires, and wires that are being pinched. Check your battery cables for tightness on both ends. It seems like something is shorting out when your engine tips when you put it in gear. Check all the wires that are anywhere near the transmission. Good luck.
