Sound,s like you have good fuel pressure,if this at the fuel rail?


But if loosing pressure that fast,something is not right with,the fuel system,should hold it for a good while.


Check the fuel pressure regulator,may be bad,

mark already changes pressure regulator no change


Are you sure the timing is correct?It take ,s timming to put the fuel and fire together,the ECM controls,the injector,s same as plug,s.
