Posted yesterday in 1st gen forum....maybe this may get more response.

Think my 93 injector pump is out. Have some good info from tyssniffen's resent posts and responses to further investigate.

I have found prices from 600.00 for a remanufactured (Web) to 2100.00 (dealer cost reman).

Has anyone tore it down and replaced the springs/o-rings etc. themsevles on these? A long time ago I met a man that worked for a diesel place and told me on these 12 valve pumps it only costs 80+ dollars in parts to tear down and rebuild.

Has anyone found these pumps cheaper than 600.00?

I just replaced on 12/31st the shutoff solenoid so I don't think it went out again. When cranking the motor am getting fuel from the filter.
I am getting fuel to the back of the injector pump also when crancking. Replaced the fuel filter 3 months ago as well.

any help is appreciated!
