I have an F-250 diesel superduty with 216,000 miles. If I plug it in at night it starts and runs fine. If I don't then it starts fine but after about 1 minute it starts running rough cuts off and won't start. I replaced glow plugs and fuel pump but now the mechanic says it has a skip and needs new injectors. Can anyone help!

 

Check the voltage. My 2003 has issues in the morning. The Alternator doesn't start charging until you speed it up above 2000 rpm. It pulls the batteries down around 10volts when it starts, but will drop enough that the computer shuts it down if you don't rev it right away to get the alternator started.

 

I will give this a try and I appreciate you responding!!!
I don't want to spend money on new injectors if I don't need them right now.

 

also look at the relay's on the left side on the top of the motor for loose or dirty connections,

 

I do appreciate this information. This is my first diesel and I'm learning.
Thanks Again!!!
