2002 cranks, no start or smoke
 

Brand new to the site, but have gotten good info in the past.
I filled up with fuel, drove a quarter of a mile down the road, and the truck died. Would not start. It cranks really strong. I replaced the cps twice with motorcrafts, no fuses are blown, I pulled the icp plug, hpop is full, new fuel filter, and there is fuel flowing into the bowl

still wont start.
Its bone stock 220k.

Ideas?

have a way to check the hpop pressure while cranking? also i'm not being a smarta but you didnt fill it up with gas did you? i've had 3 trucks towed here that had been filled up with gas when we got to working on them trying to figure out why they wouldnt start.

I don't have a gauge with high enough PSI.
it was diesel... out of the green nozzle.

if you had a hydralic pressure gauge it would work as long as it had a 3000psi max. i figured that you would have found it if it was gas when you changed the filter. thats how we found the 3 that we've had come in. soon as we took the filter off we could smell the fuel. without knowing if you have enough icp pressure its going to be hard to figure out. have you scanned it for codes to see if you have any IDM codes? that oil pumps on those trucks dont go out near as often as the 6.0 pumps but they do suffer from IDM failures much like the 6.0 FICM failures.

I don't have any engine codes. I only have a scanner, though.
I pulled the ICP plug and nothing changed.

However, this morning, I found that the batteries were drained... I accidentally left the ignition on. So I hooked up the batteries to the charger, charged one, then the other until my charger said they were good, then I tried to crank. I got one good crank then click.
I went on a hunt for my Multimeter. I have a solid 12.5V on both batteries, but when I crank, it'll drop below 6V... that's across both (+ on drivers side, - on the other)

I had the same issue with my late 99 powerstroke. I was told that battery voltage is crucial on these trucks. Has to be 12volts to turn on the pcm? Although mine ended up being a dead computer.

go get the batterys check they should do it for free. sounds like its a electrical issue

so I just replaced both batteries, truck still won't start.
I popped into the fender and examined the IDM, no water evident, and the dust was dry (it was just raining here)
I cleaned and reinstalled the IPR yesterday, and refilled the HPOP.

I did notice that there is a distinct "thumping" almost like a heartbeat rhythm, coming from the engine when I crank it.

what else can I check?

i have a used IDM that you can try if you would like. just pay the shipping then if it does fix it you can pay me for it if not then you can send it back. unless you have a way to do an injector buzz test to see if the IDM is working.

Where are you located?

Really need a good scanner on it to check ICP pressures, Duty cycle, run a buzz test...

All things could be checked in a matter of minutes.
