Glow off relay goes on , off, on, off for a couple of seconds ( believe bad GP, already changed the GP Module)
Your Glow Plug module should go on for about 15 seconds when 1st starting then it cycles on-off-on -off for up to 2 minutes, this depends on the ambient temperature, at 70* it will go for about 5 seconds. If you have bad glow plugs the on cycle can be as short as 2 seconds.
When it starts it idles bad for a second or two (knocking sound) but then works great.
When was the oil changed last ? Does it take more than about 2-3 seconds to start ? Dirty oil can cause that. A leaking injector could cause the knocking on startup.
Don't know about IH but you have to have the correct scanner to read the codes on the Ford IH engines. Don't know what year you have, but here is web sites for codes.
Takes awhile to load, wait for it.
