Model Years Affected: 1998, 1999, 2000, 2001, 2002

Average Mileage: 139,152 mi (10,000 mi - 245,166 mi)


The fuel level sensor may fail resulting in erratic fuel gauge operation and illumination of the Check Engine Light. Replacement of the fuel sender assembly is recommended to correct this concern. A powertrain control module (PCM) software update may be necessary for the updated fuel level sensor to read correctly.

    At approximately 50,000 miles the fuel gauge began reading empty when I knew it was more than half full. It was replaced under warranty. Then it occurred again at about 150,000 miles. The fuel indicator would go down much faster than fuel was actually being consumed. Sometimes it would work correctly, sometimes not. The problem continued to get worse, but I never had it replaced because I felt the estimates I was getting were too expensive when I could just estimate my fuel level by the odometer. Now, at over 300,000 the fuel gauge barely works at all and I'm also having issues with the check engine light coming on intermittently, or flashing. I didn't think the two issues were related until I read this, though I did have a mechanic tell me they may be related last summer when I had the catalytic converters replaced. Yeah, I know, I should have listened. Isuzu clearly had issues with this fuel gauge, maybe that's part of the reason they couldn't succeed in the most lucrative auto market in the U.S.

    My fuel gauge is way off right after I replaced the fuel pump module. Found a service bulletin saying that computer needs to be re-programed when you replace module. I will try and get it re-programed soon and I will let you know.

    A Firestone mechanic replaced the fuel pump. The gas gauge now reads empty all the time. The vehicle has been in the shop for almost 3 weeks and they still are unable to get the fuel gauge to work.

    After putting 3 different fuel pumps on my Rodeo, Firestone took the Rodeo to a shop that specializes in Isuzu's. The new shop fixed the problem. According to Firestone, one of their mechanics had inadvertently broken a wire that was not supposed to be broken. The new shop replaced a wiring harness and now the fuel gauge works.

    I've been experiencing increasingly erractic operation of the fuel sensor/gas guage. It seems to work normally when the tank is full to half full, but then the gas gauge needle swings wildly and the low fuel warning light blinks off and on. Beginning about a year prior to the gas gauge issue, I began having a lot of problems with the check engine light coming on randomly. When I had it checked, I was told it was nothing to worry about. After a few days to a few weeks, the check engine light would often go off on its own.
