Ive been out of town for some time working, now that I'm home i went to drive my 98.5 and it wont fire. First issue was the Fass pump was locked up. After I tore it apart and got the "drive" gears apart and cleaned everything was fine there. I now have 16psi at the injection pump. I cracked all the lines at the head, figureing I had air in the system. Exactly how much fuel should be pouring out of these things? I would think alot, and theres not. Im assumeing it should be a complete mess with fuel everywhere, I have some fuel comeing out, but not a ton. The truck will fire on ether, and I'm not pulling any codes. So do I have the injection pump froze with the same junk that had the lift pump jamed up? Or do I have air in all the lines and just need to keep working it? Tonight i will be trying fresh fuel out of a 5 gal can to see if that may be the issue. Any ideas here would be appreciated

I'm still unable to get this thing to start. Any ideas here? I'm still not pulling any trouble codes
 
what is the temperature there, where and when you are trying to start your truck? The reason i ask is because if its sat long enough with the same fuel since summer which is a D1 fuel with more paraffin and if it gets cold enough it will gel up in colder situations. dont remember the exact degree. but it will tgel up in cold weather no problem if its sat awhile.
 
Well.... Theres a brown sticky substance in the tank, I'm sure in the lines, and probably in the injection pump. I'm unable to get fuel to flow out of all but two lines from the pump. Is there any way to clean that injection pump for now, that dosent involve replacing it?
 
If you're not able to get fuel out of any other injection lines, that contaminated fuel probably caused the rotor to seize in the injection pump. While you're waiting for a new pump to arrive, definitely do a thorough cleaning of the fuel system so the same thing doesn't happen to your new pump.
