As I wait here for roadside assistance (7.3 died no start)

I'm wondering what I should start checking after I get a flatbed ride home. I unhooked my trailer at my shop and about a mile later I had a quick loss in power and than it died and would not start back up.

It cranks and the tach moves a little but shows no oil pressure (it never shows oil pressure in the dash till the truc starts).

The oil level is good on the dipstick it was recently changed
The level is good in the hpop reservoir
I unplugged my tuner nothing changed
I opened up the fuel bowl let it fill up and empty it again so I know I have fuel
It cranks strong so the 2 month old batteries are good.

I don't have a scanner so what should I start checking? CPS, ICP, IPR? Can they be checked without buying new ones? Maybe flush the blinker fluid and check the spark plugs?

Dan, it has 202k mikes no check engine light, it turns off with the other lights when you turn the key.

I'm going to start with looking at the fuses>unplug IPR>unplug ICP>swap the CPS with the one in my other 7.3.

Again, I don't have a scanner... Since I have two 7.3's I'm realizing it wouldn't be a bad investment though. What's the best option for someone who just works on their own shit?

I use a Bluetooth adaptor that I bought off ebay and the android app called TORQUE. there is a free and paid version, they are both nice and provide lots of info and when you do read the code, its one click to jump to the web browser where it gives you the whole description. Adaptor was only like 35 shipped. Works on any OBDII and is currently what I use in my LS swapped truck so I can read the computer because I don't have gauges in it yet.

UPDATE! I swapped my working cps from my '96 powerstroke into the '00 and it started up. Thanks Bones!

The bad CPS was a grey one and the working cps was the black one. It took a little longer than usual to crank but it seemed to idle smoother. Could this be because the grey one was going out or are they different?

It could be or it could be something else. The black CPS is the one ford recalled, it's also the best one that no one makes any longer. So you don't end up stranded and have to ask why your truck died later down the road... Disconnect the fuel bowl heater wrap it with electrical tape and forget about it. When the fuel bowl heater fuse blows it will leave you stranded... Beat it to it you don't need it anyways
