7.3 IDI injector problems

First post here. I have a 1989 F250 with a 7.3 IDI, 5 speed, 4x4. I recently installed reman injectors from Dieselogic.com. Before installing them, I cleaned the fuel tanks out and replaced the fuel filter. After install, I could not get the truck to start after a very long time cranking it. I gave it a shot of starter fluid and it fired up. Once the RPMs dropped, the truck started shaking really bad and the exhaust note sounded like it had a misfire. I cracked the fuel lines and bled the air out (I have done this several times now). I played with the injector timing some with no change. I saw on here that the fuel pump could be bad so I replaced that, no change. Driving around, it is very down on power and tries to die (and sometimes does). Now I have been fighting this for a couple weeks, still have to start it with starter fluid and still shaking violently. Any ideas on what could be going on? Thanks in advance.

never heard of them before now, but with 26 better business bureau complaints against them in the past 12 months, i would avoid them.
first i would do is check fuel delivery to eliminate that as the problem.
how old is the fuel filter?
have you checked it to see if the fuel is clean?
are you getting smoke out of the exhaust?
there is not much that can go wrong with these engines.
about all needed is clean fuel, clean air, and 12 volts to the injector pump to run.

Fuel filter is brand new, fuel tank has been cleaned. Fresh fuel in it. It smokes some when it first starts, but it clears quickly. I wasn't aware of the complaints against them, probably should've gotten them elsewhere.
