Low frp and high injector pulse width at start up

[podulka]

I can make it screw up every time on start up
Frp falls to almost zero and injectors pulse width goes over 1k
Truck falls on its face when frp falls
Has new hpfp
New frp sensor
Current injectors have 300k miles on them

get the injectors checked for return flow rate.
