My late 99 powerstroke starts really good first thing in the morning or when its cold, but if its been running for a while or i have to shut it off and start it several times it cranks for about 5 sec. and when it starts it idles rough for a min. Is this normal or does anyone have any ideas?

 

How many miles? It sounds like a worn HPOP.

 

233,000mi. what is an hpop?

 

high press. oil pump. It fires the injectors

 

so that would cause it to idle rough for a sec. when starting warm or hot, and if so how long do i have before i will need to replace it and how many $ would i be looking at? buy the way thanks for the input

 

I got a new HPOP on Ebay from Pensacola Diesel for just under 400 bucks. The dealership wanted 1400!!!
