i just bought a 2003 f350 with the 6.0 it has 300,000 miles on it. it 4wd automatic drw. i bought it for $1000 not running it cranks good just dont fire up. just was hopping to get some advice this is my first 6.0. i couldn't pass it up for the price. any pointers will be helpful thank you
-underhood 6.0

 

Where are you located?? first test is to pull the oil filter cap then hold the little plunger down at bottom of housing then have someone crank it over to see if the oil pump is pumping oil, you can use a screwdriver or even the filter to hold the little black plunger down. this is the drain back plunger so when you pull the oil filter you don't have a mess. Test the FICM, it is located under the coolant bottle on drivers side, there is a test procedure in the "STICKY" section of the 6.0 section.
Pull the top fuel filter cap and have someone turn key to run position to see if the fuel pump is pumping fuel.
You are right, you can't pass up a deal like that.

 

im located in oklahoma. ok i will try the oil filter an fule filter test. iv tested the FICM yesterday and it shows 48 volts. im taking this slow so it may b a few day before i get to test those. just trying to get it narrrowd down so im not just guessing. thanks for your reply ill keep you up to date to what i find.

ok i went out and checked the oil filter it was good. i checked fuel filter had barely any fuel there so i traced the lines and found the fuel tank selector (it has the optional front tank) and the filter cap wasn't even tight so i took it out and filter looked new so i put it back to geather and cycled key on ff few times till i seen fuel in filter on motor. cranked it over still dint start used a lil starting fluid busted rite off and sounds good. just wont idle. i kept it up between 1000rpm an 1500rpm for 30 min. thought maybe air in system but it still dyes if it gets down to 900rpm. what dose this sound like to those of yall that know the 6.0

 

Don't know much on the 6.0 but I can tell you starting fluid is not the way to go

 

yea i know starting fluid isn't the best i only used a minimum just to see if it kick off an it did an ran great above 1000 but 900 or below it wont
