Different Starting Issue

[poorboy1964]

Alright I'm not good at explaining things but I needs some help here.
03 with 119K I have owned it for about 7 months. Every morning and if I let it sit for more than 8 or 9 hours the truck starts then dies can only get it going if I give it throttle as soon as it fires. seams to be getting worse thought maybe bad fuel but on forth tank from different stations. It does always start fires right up but dies without throttle.

so what I have done and monitored
new fuel filters Racor
stopped using diesel kleen and 2 stroke oil ( I know but I had to try )
change oil and filter to T6

CTS shows
FICM 47.5 to 48.5 all the time
no codes
seams that 03 don't get the IPR readout in pressure,,, only in volts and it seams normal from what I've read on here.

any Idea what to try next?

My truck did something similar after i got it, ended up being injectors thatwere going bad, but I don't know if that is what's going on with yours. Once it is warm, how does it run? Do yo know what kind of oil was in it before you switched to T6? I suggest putting some Rev-x in it in case you have some stiction. Do you have a fuel pressure gauge?

[poorboy1964]

thanks for looking
I don't have a fuel pressure gauge yet on the list to do.
runs great after started, I just ran it up through Wy. this weekend and it ran great.
I don't know what oil was in before?
yes agreed on the rev-x I'll order some tonight.
when I first got the truck I threw a p0278 I think when I looked it up it was low circuit #6 I think but haven't seen that in months.

I think the rev-x should clear it up

OK you don't have to hit me in the face with a chair ,,,,,,,,,,

Let us know it that takes care of it for you

I had same prob. With mine and it ended up being the HPOP. Just ended up dying on the road one day.

That's not good news, I've had the Rev x in for about a week now with no change. I wish I could monitor my high pressure oil might have to break down and take it in,

[Handy03]

The only thing I saw change when it started going bad was my cranking fuel pressure would not be there or if it was it would not even hit 600 lbs. on my Banks IQ. My CPS also went out before and had similar actions. But only acted up when hot .never cold.

Can't you get a reading from your CTS?
