Ok I know this topic has been covered a good bit but I recently replaced my fuel pump because I was experiencing long cranking and fuel pressure test showed immediate drop when switched off. Based on these forums I went with the Bosch not an el-cheapo. Start up was great! For a month or 2 that is. Now I have the same issue again. Anyone know what causes the check valve to fail so quickly and a good long term fix?
Thanks. Philip
