So me and a friend replaced the fuel lines in my Z today and after we got everything back together it doesn't wanna start. It has fuel pressure since we pulled the fuel hose coming out of the fuel filter and fuel shot out everywhere, but its just not wanting to turn over and the ecu is reading code 55. Any help or suggestions would be greatly appreciated.

Does it crank? Or do you get nothing when you turn the key?

It does crank, but doesn't even attempt to turn over.

We pulled the plenum to replace my fuel lines.

CAS, MAF, PTU all connected? All grounds reconnected?

Sure you don't have the send and return fuel lines reversed?

I'm positive that the feed and return lines are in the right spot and yeah all those are connected. I'm at a loss.

TPS connected (both connectors?) That's my last guess.
