If it is in fact glow plug problems, some of the dime store code readers will not pick up those codes. Get a good code reader that can read any of the modules in that truck. And let us know the readings.
The OP said something about hard starting..... cranks slowly,.... cranks too long of time,.... starts on one or two cylinders after a short crank then fires on more cylinders until all are lit????? Let us know.
A good code reader/monitor will save you money not spent on un-needed parts.
