2002 hard start

[dougfishing1012]

Hello,

I've been reading this site for a while now and decided to let the experts on here tell me what I probably already know but don't want to spend.
Kinda long winded but wanted to provide as much info as possible.

Here goes: 2002 f350, gotten progressivley harder to start without plugging in and or starting fluid. After about 10-15 minutes of warming up it runs fine and gets 18-20 mpg. I had a remaned engine done about 30,000 miles ago. It runs great. At that time one injector tested bad so they replaced it, should have done all. (bad money saved I now know) The truck has 312,000 miles on it now. In the past couple of weeks I have replaced the following: glow plugs, relay, wiring harness, valve cover gasket, pig tails, camshaft position sensor, IDM and o ring kit on HPOP. The starter and die hard gold batteries are maybe three months old.
The glow plug relay has 11.4 volts for 45 seconds on four test approx. 2 minute apart. That holds true under the valve cover gasket at the terminal to the GPs. The injectors had 4.4 volts to them with the ingition switch on but not started. Oil level in HPOP 3/4" from top and fuel filter and level ok. I only pulled the drivers side valve cover to test, I have no reason to think that the passenger side would be any different.

I figure it must be injectors. I had it at a new shop by the house for diagnostics but didnt get very specific results. Let me know what yall think.

Thanks
