No suction

[Greg T.]

I have D&S pumpstand from 2019. Recently cannot get suction from two of the injectors in the same bay. I've replaced hoses and footvalves to the bucket, solenoid guts, coils are good, even replaced the white I/O box in the control panel. Still no suction. What else is there?

The injectors themselves?

Thanks,
I've replaced both injectors w/ brand new.
The pump is working fine w/ pressure at 180 for low and 900 for high.

What kind of injectors do they use?
