Take out the two allen bolts from the cold start valve. Pull it out of hole so you can see other end. Crank engine and see if fuel comes out. if not check temp sensor and loosen the fitting on top of the cold start valve and see if fuel is there. if it is apply ground and voltage to plug on injector if fuel does not come out there is the problem.

When you cycle the key that is priming the fuel system so accumulator does not matter at that time. accumulator is mainly for warm restart when the engine is cold the system will squirt extra fuel through cold start valve which will give the system time to prime itself. when the engine is warm cold start valve is not activated and without the accumulator would need lots of cranking to prime system
