No start flow chart
Regarding the block heater, the cord may be bad or the heating element may be bad. The cord can be removed from the element and tested in just a few minutes.
Also, your glow plugs or glow plug GPR may not be working properly.

No start
03 Diesel Ford F-250 7.3 Everything but the heater to warm up motor during cold weather works. I’ve checked batteries. Glow plug is lit when plugged up but motor turns over but will not start.

What do you mean the glow plug is lit. Our trucks don't have an indicator that shows the glow plugs are working unless one is added. You can watch battery voltage and see if they are drawing current.

Welcome to FTE
I replaced my Block heater with this unit, 1500W, Made in the 🇺🇸. The cord was bad and considering the unit was 16 years old I just replaced everything. It’s worked flawlessly since installation.

FYI: The WTS Light has NOTHING to do with the GPR or GP’s. The PCM will command the GPR to stay on for up to 2 minutes based on oil temps. Think of the WTS light as the PCM is telling you WAIT until the fuel pump primes the system.

I too bought the block heater that Colorado350 is recommending. I bought it after he posted his thoughts on it a while back.
I also purchased one of these and mounted it in the front bumper toward to bottom on the driver's side.
Although, we need more information to help you get your truck running again. You can always try the no start flow chart that I posted above if you don't have time to keep checking back here for a fix action.

I like the Noco plug as well, but they make a 2 outlet version. Put an onboard battery charger on the other plug and kill 2 cold start birds with one stone

When installing the 1500 watt block heater, you MUST follow the install instructions - the element is longer than the OEM block heater. When tightening the engine side of the BH you will rotate the element against a piece of the engine in the coolant passage which will cause a twist to the element and it will fail prematurely. Ask me how I know! LOL The 1500 watt does a much better job of heating the coolant quicker.

That’s the charger I installed on my truck, I use it year round when I’m not using the truck or traveling. I opted to put it on its own plug. I didn’t want the block heater running if I plugged the charger in. The charger is awesome.

Colorado, I’m also using the same NORCO charger, very nice. I run both the charger and the 1500 watt block heater on separate AC lines that goes to a timed 15 amp breaker inside the basement. No obvious issues, been doing this for several years. In the past I’ve also had a heating pad on my tranny pan to help warm up the fluid, worked quite well. I used to work in some real cold areas and the tranny heater was nice since I think the tranny shifts are somewhat controlled by tranny temps, at least that’s what I’ve noticed in the past during very cold mornings.
