Hi my name is***** will be glad to help. Check ICP actual with a mechanical 5000 PSI gauge in the ICP sensor port. Should see around 870 cranking and up to around 4000 PSI high RPM or with 12 volts to the IPR while cranking for a good pump, no leaks in the high pressure rail or injector o rings and working IPR. Verify Cam sensor signal and engine cranking RPM if the batteries are cranking the engine over too slow.

Charge the ICP sensor port with shop air to check for leaks under the valve covers. Reseal the injectors and rail if found. Also Verify you have good and steady fuel supply pressure and no restrictions or leaks between the tank and pump. Let me know
