Hi Connor. Can you be a bit clearer as to what you had changed. Google translates it to valve assembly but I'm sure that's not what you had changed.

Fuel Tank Return Valve Solenoid

What you mean by "not starting" - no crank, cranks, but does not start, starts but stalls, completely dead - no lights, does not cycle between off>ACC>IG... etc. 

As well why fuel tank solenoid was changed, what was the issue before that? 

Now in itself fuel tank return valve should not cause no start issue, regardless if there is solenoid or if there is nothing at all, but I expect the car would stall at some point and there would be VSC light. Or would start poorly (basically valve open and too low fuel pressure). 

It could be quite few things that could cause it - and information so far is insufficient to diagnose it.

Car cranks but don't start at all I've try to quick start it with the spray it's fires up but cuts straight out and there was no issues before that part was changed it started every time before this first time so am abit confused..... could it be a problem with fuel not getting to the engine?

Definitely sounds like a fuel issue.

Did you use the priming function after replacing the return valve? I suspect the fuel drained back into the tank and created an air lock.

If this is the case how do I fix this problem mate?
