#1 of 4 Chevy Venture 2002 fuel gage not working by raina09

Just purchased an 02 Venture. The van was on empty when I got it. When to the gas station today and it wont go past 1/2 tank. When im driving it goes up and down. Upon purchasing this I was not informed that there was a problem. Any advice on what to do?
 
Thanks

Fuel level sending unit is likely bad - its a common GM thing from that time period caused by the sulfur in gasoline.
 
I've read that if you catch it early enough, you can cure it with a bottle of Techron in the fuel tank as it cleans the sulfur off of the sending unit - for 15 bucks it might be worth a try but I wouldn't count on it.
 
You can also check the pass through connector - its a bundle of wires underneath the car approximately under the drivers seat - disconnect and check that the contacts are all clean. Some of those wires go to the level sending unit as well as the fuel pump.
 
Its more than likely that the problem is the sending unit though - its not a cheap repair as they have to drop the fuel tank to fix it...Good luck

My Chevy Venture 2000 started giving weird fuel readings after I put in some relatively chep gas and let it get down to the end of that tank. I don't know if the events are related or not. I finally just started jotting down my mileage and no longer relying on the dial at all. Its annoying to have to do that but if I put money into repairs I want it to be only on items tha are relevant to the actual functioning of the vehicle.

if your fairly confident with tools than do it yourself and save big!!!
 
the tank should be fairly empty. support the tank with blocks or jack stands. The tank is only held up with two strapes and four bolts. being plastic and fairly empty, the tank should be managable to slide out from under the van. The float/sending unit is very easy to replace from there.
 
Check all of your wire connections, clean and put eletric grease on them before re-installing.
