My Buick Terraza shows a pretty constant "check engine " light. When I hooked up the scan tool the trouble code "fuel system too lean" came up. I know this vehicle has no fuel filter to clog up. Do you think that the fuel pump may be going bad? My next guess was to check the fuel pressure with an inline gauge. Am I on the right track? Do you know the mean fuel pressure spec.? Thanks
