Changed glow plugs and relay still hard to start

[slayer]

2002 7.3 I have changed the relay ,and just changed the glow plugs ,and this morning it was 25 degrees and had to cycle about 5 times to get it to start, it was very choppy. When I plug it in it fires right off and runs smooth, problem is I am moving to an apartment and theres no place to plug it in. Maybe pcm? I am lost, Please help thanks.

check you batteries how old are they

I took them to advance auto and had them load tested, they said they were good

[Dave]

did they disconnect them when they did it if they didnt it wont read right

Has the truck ever sat for a long period of time without being run?? How many miles?? There is a decent chance you may need to re o ring the injectors

Yes, I disconnected them and then they load tested both of the batteries

The truck , to my knowledge, has never sit. It has 95,000 on the engine
