Had trouble with high pressure oil leak, replaced hpop, still had problems, replaced all seals in rails and injectors. Could not get high pressure, called people who rebuilt hpop, had to send it back (bad rebuild).
After time in hospital finally got hpop back in, cranked for about 5 secs and tried again after testing batts, started without turning very much, but has miss.
Hooked up ae and am getting codes
p0046 (turbo circuit range)
p0013 (intake air temp circuit high input)
p0267 (#3 injector circuit low)
p0269 (# inj circuit contribution/balance fault)
p0273 (#5 inj circuit low)
p0275 (#5 inj circ contribution/balance fault)

Also replaced wiring harness for injectors and glow plugs, replaced all glow plugs, but getting codes for half the glow plugs not working,

But the truck starts good even while cold.

Any one have any suggestions? Does the injector codes mean the injectors are bad?
The glow plug code will not affect the running after it starts, will it?

Answers are appreciated.

Thanks
