hi im new to the diesels and this site , but just got a 03 superduty f250 6.0 that wont start , did the filters and checked its getting fuel up top but still nothing , any ideas to get me in the right direction ?

 

You need to find a way to read live data from the PCM via the OBDII port. List of commonly available options:

We're also going to ask if there are any codes, so you need something that can pull those from the PCM at least.

Anything short of this is going to involve guessing, and guessing is expensive on this engine. We can try to give you a list of "freebie" tasks you can do to try to rule out certain common issues, but most of the things recommend are going to involve access to a scanner.

Our No Start checklist is in the first post of this link, and includes a link to Ford's own 2003 no-start checklist, but if you aren't mechanically inclined it's not going to do very much for you:

I'm looking for a deal I wrote awhile back, I'll post it once I locate it. Deals with why fuel isn't your issue.

 

So when you crank the truck over, does it roll smoothly? Or does it spit and sputter and try to start? If it's smooth, one of the most common no-start problems is a high pressure oil leak, or a failure of a component or sensor:

No start along those lines in that quote, that was related to a bad ICP sensor, but had symptoms of losing fuel:

You have a 2003, so the ICP sensor is royal PITA to get to, but a "freebie" is to unplug it and see if the truck starts. If it does, you have a bum sensor that you need to replace. If it doesn't start, we start looking at mechanical issues. How many miles on the truck? And have you had any work done on the high pressure oil pump or the injectors ever?

Another "freebie" is testing the FICM with a voltmeter. This is more involved to do manually, so really just buy a scanner and read the numbers off a screen instead of crawling all over your engine with a voltmeter:

Part of this is going to be testing your batteries separately with a load tester to make sure one isn't down and causing electrical problems. Most auto-parts or quick-lube places can give you a decent pass/fail load test that will suffice to make sure you don't have a completely dead battery messing things up.

The final freebie: Spin the engine over with just the starter bypass wire. The engine should roll over and crank smoothly; if it doesn't and it chugs or puffs or worse has faster points as it spins we're looking for accessory drive belt or a bottom end mechanical problem like compression or valve train problems. If it's uneven, remove the drive belt and try again; if it's still uneven it's going to get really involved really fast, so we'll cross that bridge if we come to it:

 

Don't mean to bombard you, BTW. Digest it all a couple times, we'll walk you through any parts you want in a much more detailed and step-by-step way, just trying to give you the highlights of why a no-start is hard to diagnose on an engine that's run entirely by a dozen electrical sensors. Get that scanner, and it all get's much simpler.

 

ok yeah i ordered one , figured thats the only way to find out whats going on , thank you for youre help

 

well i got a code reader abd it read no codes so a friend advised me to look at the icp , i got as close to it as i could and found the connector all oil soaked and figured thats the issue hopefully so im going to get someone to replace it for me ive bought the special socket and ordered a new sensor , well see how that goes ,,,

 

ICP should be a standard socket, 1-1/16" for your year if I remember right. Later models on the valve cover is 15/16" or 24mm, some people replace the early model sensor with a later model one. The IPR requires a special socket with a cutout; right next to each other on your truck, but make sure you pull the sensor and not the valve out if you think that's the issue.

If the pigtail is oil soaked, it needs to be cut out and replaced also:

Late model sensor:

You can see the size difference between the two in the pictures, the late model flats are pretty significantly smaller.

 

ok cool i didnt know they were interchangable , is there a advantage to it ? thanks

 

The late model one seems to fail less frequently is the only real reason I've heard floated. I'd make sure you buy a real sensor in a Ford parts bag, not an aftermarket brand.
