You don't say which type of pump you have ,there is two,oildyne is one one of them I know you can bleed off the pressure, and allow the cylinders to go down,also listen for the "solinoid to click if you push the switch up or down if it does not click then you have found your problem,check connections too see if they are clean of corrosion as well,good luck.

There also should be a fuse on the pump, did you check that? hammering on it with a sleg and 2x4 is not the answer, there is a reason why it wont go down, just have to problem solve it.

There is no bleed valve ( I am assuming B3 drives?) on those drives. Typically this scenario means the end caps on the trim rams are corroded and need to be replaced.

There ios twice as much pressure trimming up then down, so up pushes past the corrosion.

The pump moves engages and pumps fuel out of the line when disconnected so fuse and solenoid seem to be good. If I remove end caps on cylinders and disconnect drives they do come down. I am trying to figure out if something is wrong with the drives.

That should read Oil not fuel

What do the caps look like?

If there's no oil pressure, the only thing holding up the drive is the rams.

Let me ask this: Do the rams go up and down when disconnected from the drive and with the pump and system full of pressure? If not, could be a valve in the pump.

Kevin thank you for getting back to me. The only thing holding up the OD is tHe rams. I will will have to fill the pump with oil, disconnect the OD and try to move the rams. Where would the valve be? I will be out working on the rams Thanks again. Al Fauvell A7Fauvell@aol.com.
