01 Blazer couple questions please - 7/4/2007 1:20:14 AM    whurston@yahoo.com   Posts: 2 Joined: 7/4/2007 Status: offline Hello, just bought my 3rd 4.3 vortec vehicle.  I love them but I need a little bit of help from you guys please. Couple questions.. 1.My fuel gauge is bouncing around intermittently and is not being accurate. Also my blazer cranks a little bit before starting. Could this be the fuel pump causing both problems? 2.How do you check if the fan clutch is bad? 3. My headlights and panel lights flicker a little while idling at low speeds..... any idea why? I really love this truck I just wanna work out these bugs. Thanks so much everyone! Post #: 1

Do you by chance know if the fuel tank has to be dropped to get to the fuel pump on this vehicle? I found a few on ebay for around 100 bucks plus shipping so I'll get that done before it leaves me out in this Phoenix heat.  Thanks again! (in reply to aircrewman) Post #: 3
