Hi, i'v recently acquired an 07 ML63 with 120,000 kms on the clock. The car has undergone almost 10k worth of repairs under warranty in the last few months and now right out of warranty im having a huge issue.

I drove the car to a function, jumped back in it half an hour later and tried to fire her up but couldnt get it to start until 3 or 4 attempts. eventually when it started it made a rattle noise from the motor for a second or two then dissapeared.

though maybe bad fuel? drove it till empty, put injector cleaner, full tank of premium fuel from another service station and still no luck.

Took it to my mechanic who generally builds high performance jap imports as he was my regular mechanic and scanned the below codes.

He admits not having much experience with the 63's so im baffled as to what this may be, any help would be greatly appreciated

I should mention car has an exhaust system fitted with cat/resonators deleted and the rest is standard

Does it sound like this or similar?
All those codes (in brackets) in the first image relate to each other. Search them on here and you will see a bunch of threads.

The fuel pressure sensor is under the rear seat in the C63. Could be a faulty sensor or wiring.
