Glow Plugs or Injectors?
I have been having a heck of a time getting my 04 6.0 to start. At home overnight when I can plug it in it will fire right up in the morning no problem at all, but when im at work and the truck sits from 7:30 till 5:00 it will usually take 2 or 3 trys to get it to fire, and thats running the glow plugs for 30 seconds 2 or 3 times before I try to start it the first time. then once it fires...look out, sounds like the motors is coming apart from the inside out. After about 30 seconds the idle will smooth out and after that it runs just fine. Oh and this started when the temp was only down in the 20s. I have discovered that at noon if I run down the road to the gas station, or if I don't go anywere for lunch just let it idle for 10 or 15 minutes, come 5 oclock it starts just fine. Dose this sound like an injector problem or mabey something to do with the glow plugs?
Oh and one more thing, lets say the truck is up to normal operating temp, I stop at the gas station to fuel up or run into the store real quick, anytime the truck is shut off for 10 or 15 minutes and then started again, I notice that at low RPMs (1000 to 1400) such as just pulling out of the parking lot it has a deep tone to it and dosn't have that classic powerstroke sound to it untill I get out on the road, mabey somthing to do with my starting issue?
