I have a 99 7.3l turbo that ran fine last night but won't start today. Wts light is not comming on but have had the block heater plugged in for 2 hours. What could be causing this issue? I was told by a friend it could be the CPS ( cam pos. Sensor ) but this is my first diesel and bought it used 3 months ago. Prior to this, the engine has stumbled a couple of times while driving but no other problems.

 

wouldnt be the CPS when mine went out my wts light still came on,

any blown fuses or anything???

 

Check your fuses, sounds like the fuel bowl heater shorted, taking out the fuse, which also powers the PCM. I cant recall what the fuse number is, but its under the hood by the air filter box. If that fuse is blown, before you replace it, reach under the fuel bowl and unplug the fuel bowl heater.

Its not the CPS if you have no WTS light.

 

the fuse could be under ur dash too, my cousin kept blowing the fuse under the dash when his fuel bowl heater shorted out
