02 7.3 powerstroke problems!

It's hard to start hot or cold ....been having to use starting fluid. Sometimes when I first try to take off I can hold it to the floor and it barely runs....After a few min's it picks up and has just a like mis . Like it's not getting enough fuel. After a few min's more it starts running fine, it shifts rough and it takes a while to shift into overdrive...It runs fine after it warms up. and shifts fine. Unless I let it set for a long period of time...Like at work for 8 hours or so....I have changed the TR sensor on the transmission and the fuel filter...Added injector cleaner...air filter....But still no change! ANYONE have any Ideas?
thanks for your help !

if this truck has high mileage , sounds like you have injector sticking issues , very common with higher mileage 7.3, is the maintenance good on this vehicle

I am sure you know that you should really try to avoid using starting fluid
to start a diesel. Much better to plug it in until the issue is fixed if at all possible,

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.
