First off this is a bone stock 7.3 Early 99 F550 120,000 miles. Roughly 6 months it started running rough, no cel
but other then that was fine and tolerable. No problem with cold winter starts. Now with in the last 3 weeks it started puffing white smoke, not just on cold start up just regular driving. Consuming oil, very hard cold starts, loss of power, stalled a few time. As of last week would take about 1/4 mile to get to 25. Unplugged the map
got full power but still running rough but use to it. So I plugged the map
in left that alone, check the icp
sensor to see if it change with it unplugged started to idle surged so I plugged it back it and it ran rough but had full power again. So everyday until it died would start it up, unplug the icp
, to reset the values, plug it back in and would run under full power all day. Then finally 2 days later stalled and won't start now.
Fresh oil changes as regular rountine maintence rotella 15w40, new batteries (3 months ago), new alternator (same as batteries), glow plugs and relay (8 months ago), new fuel filter, air filter, map
sensor, cam sensor, icp
sensor from working candidate,quarter trick for uvch, new idm
, switch ipr
solenoid from a working candidate. Only thing I have really check with a snapon scanner was crank signal which is good, icp
pressure signal was at 1900 psi
while cranking, good battery voltage, fuel bowl fills up when energized, no smoke while cranking, wait to start light comes on, check fuse for fuel heater good, Unplugged icp
sensor tried starting (no dice) wiggled ipr
connector while cranking nope, I know ether is a no-no but will run only on ether, check fluid level in hpop
inch from top. The only thing I just realize is I the idm
I recently purchase my father just plugged it in to see if it would start, and I'm almost postive that has to be grounded to the body so definitely trying that tomorrow. What it seem like to me is the injectors aren't getting fuel, I know absolutely nothing about diesels.
. I'm at a loss, haven't got into the any electrical yet, that why I'm posting hopefully someone can help me out. I need this truck running it for my fathers business.
