99 dead
I have a problem in my 1999 f250, I parked it and it ran fine, the next morning I started it, I noticed it was idling rougher than normal went the house to let it warm up, and it started running very choppy and died, it would not restart, just fire on one or two cylinders randomly and blow diesel fumes out the eghaust like its getting plenty of fuel, I have tried a new injector driver and, have not tried a cam sensor because I was told if is getting fuel than it is good, any ideas?, anything would help thanks

The cam sensor can be a funny thing. The quick check on the 99's is to watch the tach while cranking. If the tach bounces, then the PCM is getting a signal from the CPS. If the tach sits still, change the CPS.
Since you've already replaced the IDM, I'll assume you've been fighting this a while. Hopefully you've been keeping the batteries on a charger while you try to figure this out. If battery voltage drops to low, the IDM will not fire the injectors, so even if you changed the bad part, the truck still won't start with weak batteries, regardless of how well the motor sounds like it's spinning.
How familiar are you with these motors? Have you checked the oil level in the HPOP reservoir, or tried unplugging the ICP sensor? (If you don't know what that means, I'll dig up some pics)

ya, I just changed the cam sensor, and the computer next to the e-brake pedal, I also tried unpluging the ICP sensor, it would still not start just threw a code about the ICP, I am not real familiar with the motors just what I have learned in the last week or so, I have been keepin the batts on a charger, after changing some things I tried starting it and got it to fire once, but that was it, I made sure I was getting good power to my glow plugs also, then I checked the fuel pump on the fraim rail it is also running like it should, should the engine start with the ICP sensor unpluged, and how do I check the oil in the HPOP reservor? thanks a bunch I appreciate the info

Yes, the engine will start with the ICP sensor unplugged. The PCM assumes default readings if when the sensor is unplugged and throws a P1280 code.
HPOP reservior is on the front side of the motor. There's an inspection plug you can remove to check the oil level (same oil as you put in the engine). It should be 3/4" - 1" from the top.

If the glow plugs were not working it wouldn't even start. Once it's running the glow plugs are not needed.
Dead fuel pump.
They are here today and gone tomorrow, with no warning.

thanks, I checked the oil level in the HPOP reservor and it is good, I came home today from work and it almost started, I think it fired on about 4 or 5 cylinders but quite after bout 5 secondsI got a code shortly after, but was dumb and did not write it down, I did not clear it but it went away, I thought you had to clear codes before they disapear, I just dont understand why the engine turns over fast, blows all kinds of diesel fumes out the eghaust but will not run, it almost has to be the glow plugs, but why did it die in the first place, and the glow plugs are drawing lots of amps so they have to be putting out heat, I can mist the air box with starting fluid, it will start but then die it makes no sense

Do you hear the fuel pump running when you switch on the ignition but not try to start it?
It will run for 15 seconds then shut off.
It is mounted in the frame rail directly below the driver's seat inside the U-channel.
Small electric motor looking thing.
If you have power there and no whirr, you need a pump.

As far as blowing the smoke out the tail pipe, if you don't have adequite fuel and the injectors are just sucking the leftover diesel foam that is in the fuel rails, you will get smoke, but not good enough fuel atomization to actually get it to fire.
Or it is not injecting enough fuel to get it to run, but it will make some smoke in the attempt.

2000 dead??
mine was killed getting out at the Ford dealer and when i got back in it, rapid clicking when the key was turned on. turns out fuel pump was clicking, later found that ac relay was clicking because new fuel pump didn't do it. have 12v at batteries and terminals, so i assume my connections to be good. one right bank ground coming from battery has 12v the same, but all other body grounds show 1-2v less. if i take out ac relay, clicking doesn't happen, but won't start.. jumped 12v to ipr because I've been fixing on it(was picking up rebuild kit when this happened) but it still didn't start... lots of smoke with ipr jumped, but only clicking with ac relay back in its hole
😩😩😩🤦♂️i messed up now it sounds like it's trying to hydro lock when i turn it over
found some relays behind radio...
