Truck won't start
I ran down the batteries trying to start my truck last week it's a 99 psd. So I got someone to try to jump my truck the voltage got up to normal on my volt meter but when I tried to crank it the voltage went down to 5v. When I crank it it makes that sound like it is trying to turn over but dosen't. So my question is do you guys think it is the starter that is bad?

Get a good charge on the batteries first. After that - does the starter turn the truck over or does the starter just click? If it does turn over, do you get a tach indication of RPM? If not then check the fuses under the hood. While at it check all the fuses just in case.

I'm guessing the batteries are too discharged - whether they can be salvaged or not is another queston entirely - but it takes a whomping amount of recharging to put power back in *two* big diesel batteries once they're run down. Someone hoooking up to your batteries with jumper cables from a mere mortal vehicle for a couple of minutes doesn't even scratch the surface.
Try charging the batteries one at a time with a stout battery charger, or for a day or two each on a trickle charger. If you are parked at home and can leave the batteries in the truck, disconnect one battery at a time and charge the disconnected one. This way you're not trying to charge both at the same time, plus if you never have both disconnected at the same time you won't lose your radio station presets and such.

Is it cold where you live?
I had the same problem last year with my 2001 psd when the temp starting getting colder. I ran my batteries down several times trying to get my truck started. I found out it was my glow plug relay that had went bad. After I got that fixed I had no problems at all. You might want to look into it if your problem has just started with the dropping temps. I ended up replacing my batteries later on because cracking on them so much ruined them. Good luck!
