Chevrolet captiva 2009 LTX VCDI
Hi guys I took up the challenge of changing the fuel pump on my 2009 captiva at the weekend as it hasn't been reading properly for a while now. 2 days later I finally had it installed 😑. I filled the tank to around half full and the fuel gauge read half a tank and the digital millage read 203 miles I then went for a 13 mile drive and the car read 190miles left so I was pleased and thought that the new pump had solved the problem. The the following morning I went and filled up with £30 more of diesel and that's when everything went down hill the car read full tank on the gauge and on the digital read out it read 348 miles then half a mile down the road it dropped to 300 miles then about 2 miles down the road it dropped to 280 miles. So basically it's just chucking random number out at me I know i have close to a full tank in the car. When I changed the pump I checked the sender unit and all the connectors that go to the fuel tank and also all the fuses and relays everything seems fine. So I am now scratching my head wounding what the problem could be. Any suggestions would he HIGHLY APPRECIATE!
