Hi, just need some verification, Have an 2003 Mercedes S55 amg, Have an no start situation, Had suspected I wasn't getting any or enough fuel pressure, checked all fuses and relays, especially the fuel pump relay and fuse is good, control module are good, have power running through it, checked with multimeter and test light, no codes on scan tool, bought an fuel pressure kit, found i had zero pressure, so I am assuming this can only be the fuel pump itself, car has 160,000 miles, fuel pump has never been changed, Come on guys, give some feed back please?

 

Hello and welcome to the forum! Based on your assessment, I would agree that it sounds like the fuel pump. If you have any questions on the replacement, please let us know - I'm attaching a link to our catalog for your 03' S55 below.
