2000 Hard Start cold and runs rough read message

I had several injectors that had the plunger and bores sticking. Dead skip cold and rolling skip warm. It did not matter if it ws plugged in or not. I purchased
8 reman injectors, glow plugs, valve cover gaskets and harness. Since I installed all this it doesn't want to start cold unless I plug it in. It will fire and fire several times
then may start after several times but rough very rough. Vibrates, seems to skip. I let it get warm for 5 - 10 minutes shut it off and restart it runs great. If I plug it in starts fine. I tested glow plugs ok. Connected Ford IDS and performed tests. Passed all tests enven when it would not start. ICP 950 pounds cranking, injected passed all electrical tests. There was several codes in the system mostly EBP codes but also has P1280 ICP Sensor circuit low P603 Power interuption on KAPWR and P605 PCM memory failure. Cleared codes P1280 came back in continuos memory. I found a TSB relating to P1280 wire ends. Anybody have any ideas? I do not think it is related to the glow plugs but it is heat related. It also has new batteries and glow plug relay.

Next time you cold start it, watch the oil pressure gauge on the dash. I'm curious to know if it ever comes up and shows pressure before it dies.

I had an issue several years ago where my LPOP was worn out. On cold starts, the truck would fire, run for a few seconds and then die. What was happening was that the injectors were running the HPOP reservoir dry before the LPOP could fill it back up. Since cold oil doesn't flow as well as it does when warm, it was only a cold start issue. It also would run rough and have no power if I tried to drive it before it warmed up as the oil would end up with air in it in the HPO rails. It was also worse the older the oil got.

New LPOP solved the problem.

Thank you for the reply but enven when the engine is cranking the gauge will
come up to normal range. It also shows per the IDS that I have approx 900 lbs high pressure oil.

Have you tried starting the truck with the ICP sensor unplugged?

Yes I did, still no start. I also found out it set code P1280. I cleared all codes and the only code that came back is P0470 exhaust back pressure sensor circuit.

Okay, next cold start, turn key on, use a screwdriver or other piece of metal with an insulted handle to jump the two big posts on the GPR for about 30 seconds or so. Then start it. It would be even better if you could get someone else to start it while you are jumping the relay. Obviously, Keep your extremities and whatnot from catching the belt or the fan.
