2004 6.0 Need Help

[Keith_1987]

i have a 2004 6.0 f350 it has 132,000 miles. truck has a lot of trouble starting sometimes must use starting fluid. idle is very rough and has no power when trying to drive sometimes it cant do 5 mph and sometimes it can do 45 mph or more. Sometimes it seems fine and has normal power for just a min then no power and tries dying. Have installed 2 new batteries, i have tested the ficm and it maintains 48v or more all the time. I read to test the icp valve i could use a dc multimeter. So i cut back the blue and gray wire and tested volts while cranking. Never got over 0.3 volts. So i think i am having a hpop problem??? What do you guys think
Thank You

Also when truck is idling oil pressure drops to 0. When idled up a little bit oil pressure is normal. When cranking the truck oil pressure gauge stays at 0. I have cranked as long as 20 sec and no oil pressure build up

Ok so I was done for the night and can't get truck to even start I was going to pull it back it the shop but it won't start. It won't even start using starting fluid either. I removed the oil filter and pushed that part down and the canister filled in apprx 10 sec. So I think it's definitely the hpop but would like some input from others

Sounds like it, a gauge set is also something you should get, monitoring your ICP/IPR values would let you know. ScangaugeII is $160.00 at Auto Zone.

Man I would NOT use starter fluid on that truck.

If your cylinders were to fire out of sequence using starter fluid you could damage your valves, pistons and even the crankshaft. If you had no glow-plugs or had disabled the GPCM relay, then you might be safe to use it! But why, if it isn't running correctly, you really don't want it to break-down away from home! For example, now how are you going to get it into your shop? Tow it/push it with another vehicle or tractor?

You need gauges of some type. Your ICP should be about 0.8v (500 psi) to get the FICM to give you fuel. With your at 0.3v, you need to know what your IPR is doing and if it is broken-open. With the trail of it getting worse over time, the indications are leading to an HPO problem of some type. In any case, if your HPOP is bad, change out your IPR as good practice.

Ok so no more starting fluid. I have ordered a obd scanner thats suppose to hook up to my laptop hopefully it will show what my icp and ipr is doing if not i will go to autozone and buy one. I guess i need to find out what these icp and ipr values are to see what the next step is. Thanks

If that scanner you ordered is the AutoEnginuity you made a good purchase if you bought the Ford specific software as well, you will need it to access the 6.0's info.

Mhatien I bought a scangagell at auto zone. Now when I plug it up what do I need to do to find the values I need. Thanks

Btw it also had a p2285 injector code also

Ok so I bought the scangageII and programmed the ipr and icp. I then did that gauges and didnt get a reading on the icp gauge but I got 14.4 on the ipr. So with these readings what should I suspect my problem is? Any help would be appreciated. I need to get this truck going by the weekend if possible thanks
