My truck quit running (last thread I made) I pulled the pump out its a db2, i checked the inlet fuel screen its fine, solenoid works the back part of the pump (where the fuel filter is closest to) does not turn, the front turn very freely and has some slack in it but it does not turn the back end of it. Any suggestions on how to get this pump working again or and ideas on what is broken please let me know.

 

Your best bet is to get a rebuilt one from a reliable rebuilder.

 

Sounds like the driveshaft sheared, the head's probably seized. If that's the case you'll need a new/ rebuilt pump. See a reliable pump shop like Jeff said.
