Alright so first I am new to this site but definitely looks like there is a lot of good advice I can get from it. I just bought an 03 f350 crew cab short bed with 107,000 miles. Its got head studs, a bigger fuel pump, injectors and a Garrett turbo, not exactly sure of the sizes and is on a predator tuner street tune. I drove it 3 hours home on Friday in which it drove and ran absolutely perfect. I stopped a few times and it started right back up everytime. The guy I bought it from had said that he had to spray starter fluid in the intake a few times over the last year that he had it and that he had to do that on Friday to start it after it had sat for a week.
So, I got it back home perfectly fine, NO problems at all. I went out the next morning to start it and it would not start. I tried using starter fluid and after cranking on it, it would fire up as you spray the starter fluid in it. However it would run very rough and would seemingly cut off within 20 seconds of adding the fluid (im guessing it would just run til it burnt it up). It is not throwing a check engine light so I am kinda stuck on whats wrong with it.
I was told that he had replaced the ICP 8 months ago. So I started checking other possible causes. Both batteries are only 4 months old and pulling plenty of power. I did a voltage test on the FICM and it stays right around 47 when the key is on and when its being cranked. I also replaced the cam sensor hoping that it would fix the problem. The fuel pump is cutting on like it should. I checked all fuses and they are all good.
This is my first 6.0 and I honestly don't know a whole lot about them but I would like to either fix or at least figure out the problem before I take it to the shop. I am guessing that it is a cold start problem since it was fine the day I got it and it was already warmed up. I am just stuck as to what it could be thats causing it not to start up and stay running. I'm not sure whether it could be glow plugs, sensors, egr. Im just hoping that its something small that I have overlooked or something. Any advice or suggestions would be greatly appreciated. I don't want to start my experience with my 6.0 off in a bad foot.
