#28 of 35 Re: '01 venture problem... fuel level sending unit by huntr May 23, 2008 (5:43 am)
Replying to: dsmothers (Sep 25, 2005 9:55 am) The gas guage on my '01 Venture is not working right. Fll then straight to empty at +/- 350 miles. Understand it's the fuel level sending unit on the fuel pump. How do I drop the tank to get to it? Something I can do in the driveway? Replies to this message: wq2121 (May 23, 2008 7:47 am)

Replying to: huntr (May 23, 2008 5:43 am) yes...it is pretty easy...it is a plastic tank, so it is light. empty gas as much as possible and then depressurize the lines (simply remove the fuel pump relay from the fuse box while the engine is running, and that will do it!), turn off engine, disconnect negative battery terminal, disconnect the two fuel lines and the electrical connections and remove 3 bolts that hold the three straps up. then unscrew the huge lid on the tank, but be careful as you then have to tip the unit as you take it out, since the sending unit goes horizontal in the tank. Just do it slow, and you'll realize what I mean. Hope this helps...

Replying to: chases (Oct 16, 2007 9:03 am) I am havinghte exact same problem! I climb under the van and wiggle the plugs and the van fires right up, but then dies in the middle of driving, have replaced the plug but now think I need to replace the actual module that it plugs into behind the drivers seat. Need to find the part but don't know what it's called? any idea? Replies to this message: wq2121 (Jun 22, 2008 9:26 am)

Replying to: criskim (Jun 21, 2008 6:19 pm) Hi, Which exact problem are you having? These threads don't seem to run correctly. Anyway, I ran 12v directly to my 2000 Chevy Venture fuel pump, bypassing the "module" that is to supply that 12 volts. I think it is called the ECM (electronic control module) or something like that. I would like to replace mine as well, so I can get rid of that direct 12v (fused, and only on when ignition is on) wire! By saying it is behind the drivers seat, you mean INSIDE the care, on under the car and behind the seat, right? Just curious.... I have no idea where that module is... Jim

The gas hand on my van is floating and I need to know if there is a drain plug on the tank so I can change the fuel mechanism. Thanks Replies to this message: wq2121 (Jul 05, 2009 8:14 am)

Replying to: dj_79 (Jul 04, 2009 1:06 pm) Nope, no way to drain it other than sticking a hose down the fuel tank inlet, and syphoning it out. The tank is plastic, so it is light, even with a couple gallons left in it. Only three straps hold it to the underbody, so you remove 3 bolts, and the electrical connections, and the two fuel line connectors, and it comes off of the van. But it is hard to find just the mechanism... they want to sell you the pump and top asm complete for like $250-300 dollars. There is one place on the internet that sells the "fuel level CAM" for like 20 bucks, but I called them since there was no picture. They couldn't send me a picture, but told me to go online to another site, which I didn't have access to, so not sure if that is the part you would need or not. Let me know if you have success just buying that item, as I need it too.

Thanks to all for sharing .... Wife's Chevy venture has been stalling and getting progressively worse, now won't start. I surfed the web this morning finding numberous builltien boards and a common theme in most, crank sensor, fuel pump, or the wire harness connector under car behind drivers seat. Easies (and cheapest) to check was electrical connector. First, confirm symptom, turn key and listen under car, no fule pump hum. Pulled connector and reseated a couple times, try again, car starts. Examine connector and sure enough the one pin is discolored around it in the connector. Clear sign that there is excessive current draw, causing heat, causing oxidation, etc. Eventually you end up with an "open circuit". Small file, contact cleaner and short time later, car starts better than it has in months. My experience in a similar inductry, this is a temporary fix. Once these connectors and pins get damaged, they will eventually need to be replaced. When that time comes, I will cut the wires and install another heavier connector for the fuel pump circuit. Thanks to all for sharing, it led me in teh right direction, and I suggest everyone wiht similar issue, listen for fuel pump hum when you turn teh key, and if you don't hear it, go to this connector first!
