Wont start unless plugged in

I know this has probably been brought up before but ny 99 7.3 will not start in cold weather unless it is plugged in. The glow plug system checks OK. I just replaced the batteries and that didnt help. Anybody had this issue in the past and how did you fix it.

you might check your fuel heater........the glow plugs heat the air to a set temp. and one or more might be heating up but not heating enough...........ohm the glow plugs...they should be at least 1.5 to 5.0 ohm's......

Sounds like glow plug system, double check the relay then might have to check the amp draw on the plugs. That’s much better than my other thought of low compression.

Thanks for the responses. Numerous items were checked by "scanner" including the glow plug system. Everything checked out "OK". I requested my mechanic to physically remove the covers and look at the glow plugs himself. With much hesitation (because the ^&%^ing scanner showed that the plugs were OK) he agreed. Sure enough - they weren't "OK". After market glow plugs were installed prior to me buying the truck and 3 weren't "grounding". Once again - the scanner showed that the glow plug system was "OK". Ford plugs were put in an no further issues. Thank you all for your input.

Glad you got it going. I’d look into getting a new mechanic that knows what he is doing instead of trusting a scanner. How the heck can a scanner diagnose the glow plug system? All the computer controls is one little ground wire and the is no feedback. That’s why I do all my own work, I don’t trust mechanics.
