New solenoid?  Is the solenoid engaging?

Yes new starter and solenoid all it does is just click he took it back of (starter) and turned it by hand put it back on and nothing but clicking sound comming from it and like i said new starter&solenoid and worked fine a few times and now this again its the same thing his old starter did.

Is the battery charged. Do you have a big enough ground cable going to the engine?

a solenoid will get stuck if not enough juice.  Tap the starter/solenoid with a hammer lightly then jump it w/ another vehicle and see what happens.

Tighten all of your wires connecting to the starter and battery cables as well.

if your hearing the click the starter is getting the power just not engaging. this could be low power but thats usually comes with multiple clicks. or bad starter/solenoid. try jumping the starter see what it does. but more than likely he should just return the starter and get a new one

I think he has done all that , i know that battery is charged and the cables he has gone through and checked he has tapped the starter and nothing just clicking his old starter i know when he took it off he tried to jump it to get it to turn over and it wouldn't and think he said he put power to this one to but not sure , the bad thing is he has a 2000 3/4 ton chevy pickup that he just got running he took it out and a few days later went to try and start that and its doing the same thing ! and it has a pretty new starter&solenoid on it he had a problem with the timming on that truck but strange how both won't start and doing the same thing.

Is he using the same battery for both trucks?  I would say to get a new battery. I just had a starting problem with my 78. Same as you say one good crank than the dreaded clicking.  Took battery to autozone for there free check. They said it was good. Had them check the alternator next and it was bad according to there check on it. One new alternator later and it still would not start. Back for the battery and I have had no  problem since. That battery was junk even though they said it was ok.

Was it a rebuilt starter? I have seen rebuilt starters fail soon after installation. Most are ok but every once in a while you get a dud.

Guessing from your name, your located in VT? If you were close enough to me I have a starter you could try. It takes me about 15 minutes to get to VT.
