Hey stoneage I had my '94 devilles's fuel preasure checked today and it was 30psi the service manual my brother has says it should be between 9psi and 13psi,so it looks like its pushing way to much preasure out. The mechanic says it looks like my fuel preasure regulator is bad and will need to be replaced. This is good news in a morbid way as we were thinking it was my fuel pump. When I told the mechanic how it acted up when it dropped below a half a tank of fuel he said that an FPR could cause this,could it stoneage? Should I sitll be looking at my fuel pump as the culprit or should I just change my FPR and go from there? Thanks for any help stoneage on this issue.
