1998 GMC Sonoma pick up with 4 cylinder automatic transmission. The fuel line mounting bracket located on the bell housing rubbed a hole in the fuel line allowing gasoline to drip on the hot exhaust pipe. It took three dealers and a couple of months to find the leak. General motors stated this was normal wear and refused to repair or assist in repair with estimated cost of $400-$600. This leak presented an extreme fire/explosion hazard. I have never seen or heard of a gas line rubbing through on any vehicle. There is no way this is anything but a design/manufacturing problem.
I have had two of the six injectors on this truck replaced. Each at a different time, now, it seems as if more than one has gone on the blink. Not sure what the heck is happening, but it is rather expensive to keep replacing these one at a time. I also dug up a website that shows there is a known issue with the injectors; however, I believe it may only apply to California vehicles. . Read more...
The vehicle stalled, consumer was informed the fuel pump and fuel filter needed to be replaced.
