Cool 1997 F450 Help

I just got it running but it will on rev to about 2500 RPMS...I drove it around the block and it would barley go even with the pedal to the floor...I have replace fuel filter,CPS,Barreries, and I have about 50 psi of fuel pressure...Do you think it is the ICP...I tried unplugging the ICP and it ran a little rough and the check engine light came on so I reset the computer and check engine light is off now...Thanks

not all scanners work on our trucks. some auto parts stores use cheapies and some use quality. if you can drive your truck to one they will let you use it free.

What kind of scanner did you buy? Like 1997F-350 noted earlier...not that many of them work on the diesels.

Has the check engine light come back on since your've started working on it?

Have you check the valve cover harnesses??? Look for burnt pins or melted wires.
Like Kwik said maybe low HPOP preessure. Maybe the IPR or IPR oring's????

i wouldn't rev it up like this. its not a gasser. not like its gonna clear a fouled plug or anthing . i h8 gas.............it will let you know when it wants to go.
anyways please enlighten us on the past. what brought all this on. did you just buy it??? sitting for a while????

do you know anyone with a snap on scanner? i would be curious what your running pressures are and what a buzz test turns up. have you checked uvc harnesses? is your oil low/old?
try and find a 1 man show mech shop who can help you if hes got one. you know the kind of place that isn't busy as all hell. please keep us updated.
whats the fuel like in the filter bowl? was your water in fuel light ever on recently?
