we just rebuilt the v1902, putting it back together, 2 of the 4 ports are not sending fuel through the lines, why would this be happening, motor started on just the 2 (middle 2) but obviously we need fuel to flow in all 4.
thnx.

Did anyone work on the injection pump?
How long has the pump been sitting?

Sounds like the pump is plugged up with junk.

no, not specifically. motor was torn apart a year ago, stripped down sleeved and rebuilt.
reassembled about a week ago and installed back into the Mustang 442.

would one be able to blow air from the top ports or do i need to pull it off and go from the bottom?
thnx.

Are the delivery valves tight on the pump. This is the part the injector lines attach to. If they are lose it wont pump fuel.

Your going to need to get the pump serviced / rebuilt:
Post a picture of the injection pump and I can tell you if it's possible for you to do it yourself!

We have resolved this. Thank you to all that replied.
We isolated the faulty ports individually, remove the fuel line going in and forced air in reverse.
this was able to dislodge the crap blocking and blow it out.

We got the engine running on all 4 cylinders now.
