2003 6.0 no start

[wallacesgarage]

hey everyone i could use some help on this one we have an f-250 in the shop. I dont have much history about it except for that it had no power above 50mph and was blowing white smoke and turning to black before this happened we have put 2 starters in it now and put a new cam sensor in we are getting good fuel to the secondary filter i have unplugged the icp sensor after i saw a post saying to try that and still nothing it wont even start off of either it will turn over all day long and act like it wants to start but all it will do is pop thats it.
The oil level is good in it, and the ficm is reading good voltage if someone could help give some insight it would be greatly appreciated thanks

Do you have any way to check the oil pressure coming off the hpop? It's probably the icp or ipr. Giving that you unhooked the icp and it still did nothing im leaning towards the ipr. Could also be the hpop itself but I'd check the sensors first.

given the history you discribed, I am thinking head gaskets. These trucks need fuel and compression. If you supply the fuel down the intake ( ether / wd40 ) and it won't go, it's starting to sound like a compression problem. Do you have a way to check compression? Why have you replaced 2 starters?

[wallacesgarage]

going to try and get a gauge to perform a compression check tonight and the customer blew the first starter up and the second starter solenoid cracked and arced everywhere how do you test the compression on these??

There are kits that will let you use the glow plug hole or remove the injector and use that hole. You need 350 to 400 psi to start and run. I found this tool at sears, but it's an OTC tool so almost any vendor can get it for you. Maybe you could rent one from vatozone etc.. If you pull the glow plug harness you might plan on replacing it. Sometimes they don't survive. Do you have any codes? have you check to make sure the EGR valve is not full of crud and stick open? That will produce the symptoms you described in your original post. What else have you checked or done? What year is it. Do I understand correctly that it was running when it was brought to your shop? You installed a starter and now it won't fire. Look at the last thing that was touched that is usually the problem. Do you have any values for ICP and IPR or any other data. Trying to fix a 6.0 without some solid data to work with gets very expensive and very frustrating pretty fast.

Need a scan tool to monitor ICP pressure while cranking. That would be step #1 in my opinion.

I would try to start it on WD40 again. You can also pull the ipr and look for glitter on the IPR screen if so then it's time for a HPOP. See the NO START CHECK LIST IN MY SIG
