Need a lot of help lol...could be several different issues

Ok, a little bit of background first. I bought a 97 f250 4x4 psd back in april for 950 bucks. The guy said that the truck had been sitting for a couple of months because he was having tranny issues with it and possibly needed a new injector. When I went to buy it, I also discovered that the battery cables were also completely hacked up. So, after bringing it home, I had issues regarding the title so I didn't want to work on the truck till I had it resolved. Skip ahead to late august and I finally got the title work finished (guy was a piece of crap but a long story).

Anywho, I have finally got around to messing around with it. Today I just made all new power cables for it out of 3/0 and replaced the batteries too. However, I am getting no power in the cab whatsoever yet i can get the motor to crank by using a screwdriver on the relay. I noticed that the cab to frame cable was severed while crawling underneath it. Could that be the reason that the cab isn't getting power? Even if that does fix that, I couldn't get the motor to crank over but it is pretty cold here and it hasn't been in 9-10 months. Anything I should check for?

Obviously I plan on replacing all fluids and filters but I want to hear the motor run first to make sure it does before I waste a bunch of money. Any other suggestions for me?

Here are some pics of the truck..

ok so i have done some more research and tried a couple of things...

1.wiring was backwards on the relay which is why no cab electric so fixed
2.Got good fuel pressure at about 45 psi
3.Fuses 22 and 9 are fine under the hood
4.got plenty of gas in the bowl
5.hpop is filled with oil and was when I checked it
6.a little bit of white smoke is coming out of the exhaust when trying to crank it

So, any suggestions on what to check next? I have heard about checking the cps and IDM but I am not sure how to tell if they are bad or if the cps has been previously replaced before. Any help would be very much so appreciated!

if you have white smoke the idm is ok. the cps is a start. i hate to say this but a shot of starting fluid while its cranking might be needed if it hasnt run in a while

yeah forgot to mention that, try plugging in the block heater too. It helps. Here are some important facts. Our trucks have to turn over at a minimum of 200rpm to start. so good batteries make all the difference. Also the injectors take a minimum of 500psi to fire properly. Also the bottom line fuel pressure is about 45psi. but if you have smoke then one can hope fuel pressure is ok as you said. also check the oil? you said the system was full but how was the oil? the oil needs to be clean and well kept up with cause of the HPOP system

It did appear have plenty of oil in it when I checked the dipstick but I will replace it anyways. The rpms did seem a little low actually but it was hard to tell if it was because the batteries were getting a little drained from trying to start so many times. I also noticed that the belt was just slipping over the ac pump and the pulley wasn't actually moving it. Where exactly is the cps and how hard is it to replace since that was mentioned as well. I also checked the plugs going into the valve covers and they appeared to be fine as well. I did find a nice fuel leak from appears to be the two main lines near the bottom driverside of the motor as well hurrah!

alright id say get it spinning over well first. Secondly does the tach bump when you spin it over? if so the cps is ok. But just for cause it is on the front cover of the motor. you have to get to it from the bottom with a 10mm wrench. it has two wires going to it. Thirdly the AC pulley has a clutch. if you watch closely the outer pulley is spinning. lastly that fuel leak you mention one of those is the main feed line and the other is the return. id be addressing that leak ASAP being as that might be the issue

Where the leak appears to be, there are two fittings where the lines meet before it turns up into the motor somewhere. Anyone ever have to replace those before and have any recommendations on where to get replacement lines or a good tool to remove them from those fittings? The last one I bought was garbage and just broke.

well they are just suction lines, so anything diesel rated would work. rubber will be fine and then just use hose clamps
