02 f350 Changed it all -glow plugs, glow plug relay, intake air heater relay, valve cover harness, o rings on the injectors, air filter, fuel filter, 2 new batteries. Done all this work to both 02 f350's and still hard start. If plugged in both start fine. Need help??
Joeford - could you define "hard to start", and how you go about to start
them, and the temps. With all you have swapped out, have you verified that
the glow plugs are actually turning on? Is there a big draw that you
should see with the plugs on? Intake air heater is just for less smoke
on warm up, nothing to do with starting. What fuel are you using?
With mine, when it is cold (had it down to 6-deg). I cycle the glow plugs
3 times. Letting it sit 20-seconds after the "wait to start" light goes
out each time. If you just wait for the light to go out and start cranking
it will be hard to start.
Even when it is just cool out I do one cycle letting it sit 30-sec after
the light goes out. This eliminates the "romp" that my truck loves
to do (even more so after it was chipped). Only do this on first start
of the day, or after it has sat at work for 9-hours.
