No fuel rail pressure
I did a carbon clean on my 2009 S5. Reassembled and now it will not start. Took it all apart and checked all connections. Everything was good. VCDS shows no fuel rail pressure. Electric pump is good. Changed low pressure sensor on top of left hpfp. No difference. Metered out all relevant wires to ecm, all good. Ran well before disassembly.
I'm stumped. HELP!
