Need of help

[KAltizer]

I started out for work this morning got about 1/4 mile from the house and it just quit just like I turned off the key... Now it won't start, I have not had a chance to look at it yet but the fuel pump is getting power since I can hear it come on when I turn the key. Anyone have any suggestions ? I am thinking it maybe electrical but only because the pump is running. It should at least fire right? maybe the C3 pump?

Just looking for a place to start since this is the first time in 15 years I have had a problem..

THANKS!!!

I'd start by draining the water separator, and see what comes out. Check/change filter and make sure it primes up. A pump making noise is no guarantee that it is moving fuel, or providing sufficient pressure.

Need more info on your truck, what is it? Is it cold where you live?

2003 5.9 it's not cold per say it started right up and I drove it about 1/4 mile then quit. I haven't got to check it yet as I hopped a ride to work but will check codes and all when I get home.

Yes, I will check that when I get back home from work. Is it good enough test to just open the valve and turn the key and see how much fuel comes out?
My buddy said to also check the crank sensor as he has seen issues with them.

I usually drained mine into an empty, dry water bottle, so I could view what came out. See if water or sediment settles out. Starting up, and quitting after a short ways is a classic gelling scenario, but it doesn't sound like you thought it was cold enough.

Also, my memory is little foggy, but being an early CR truck, is your pump external? I think it was a little later they went in-tank, like my '05 was.

 

[EDankievitch]

The 03 had the pump on the fuel filter on the engine. After checking for water I'd check if you've got flow from the lift pump. I'd bet that it failed. if it has then you've got options for a new pump.

Yes my pump is in the tank, my dad was a Chrysler mechanic for 30+ years and fortunately I had mine swapped to in-tank when it developed a problem before the warranty was up. It had 98,000 on it and the pump being on the motor qualified it for replacement.
I can hear the pump come on but I had to get to work so I am just looking for info as to where to start on this when I get home... Luckily my daughters boyfriend spent the night so I woke him up at 04:30 and had him tow me back to the house.
I think first I need to get the codes if any then start with the fuel system. The reason I was asking about the fan clutch is because I have had that error code come up a couple times in the past few months and saw somewhere that they can cause a drain which drops the voltage and then the ECU can't run and thus causes a no start issue.
I'll update once I get home and get more information for y'all...

Thanks!!

I got home pulled off the Edge. Checked for codes every time I pulled a connection and the only code I got was when I pulled the C3 pump connection. Pulled fan connection, pulled the FAC plug, opened the valve on the filter and it’s flowing out about the same as it normally does when I change the filter which I did about 1,000 miles ago.
I don’t see anything in the fuel either and I always put additive in when I fill up

 

[KAltizer]

Okay so I cracked the line on the fuel rail and cranked it and it’s not running out so I guess I’m looking at the C3 pump is bad. I didn’t think they would just go like that but there seems to be no fuel getting to the rail.

I would go back and do one more check. open drain on filter an bump starter, if you hear lift pump running and don't see a gush of fuel at the drain then you have lift pump problems.

Yes sir I did that more than once and I get a rush of fuel from the drain. Last thing I did before calling it quits was had my son-in-law crack open the #1 line at the injector and I cranked it and I did get fuel from there however I don't know if it's suppose to be a lot or a little since it's not actually running. I thought it would be a little bit of fuel then once it fires up the pressure comes up.
I get ZERO codes on 2 different scanners and also using the key switch reading. I do get a tach reading around 300-400 rpm's but I get nothing on the oil pressure gauge now I would think the oil pressure gauge would show something but I don't know for sure.

 

[Ozymandias]

Plug the PRV first for check , and it could be as good a sticking injector.
Anything that hinders the rail build pressure is suspected.
The Rail needs 400bar pressure first to fire the injectors.

And pray it isn't the CP3, if they fail you have worst case shavings all around in the Rail and the Injectors, pretty expensive then.

 

[KAltizer]

Thank you all for the advice... As work is going to be getting in the way of me fixing this and updating this post I am going to jump back on here and post an update once I get to the bottom of this. IF the CP3 is gone and shavings all through, I may just part the truck out as it has over 200K on it and I have never had an issue and never spent more than $2K replacing the turbo with a new one because I thought the bearing was going but found out way later after I replaced the turbo it was the A/C clutch... I might just have to buy a new one!!! I can't see dumping another $2-3 grand into this thing with it starting to rust now in spots it shouldn't be.
Thanks everyone for your insight, I promise I will update once I get to the bottom of this.

 

[TFucili]

Just a random thought, what about the relief valve on the rail?

 

[Wayne M.]

It helps to have diagnostics and live streaming data. Need to see the cranking rail pressure, like Ozy hinted.

 

[KAltizer]

Update:
I have checked everything and I get good fuel to the CP3 pump inline but nothing from the output. I hooked up hose from the output of the CP3 and into a water bottle cranked it about 10 seconds and got nothing out. So I’m gonna guess the CP3 is bad but I didn’t know they would just quit like that. So anyone have a suggestion on what to replace it with? Bosch reman or NAPA unit?

 

[Wayne M.]

If I needed a CP3, it would be a OEM, probably Cummins reman unit.

 

[KAltizer]

Hey, I was thinking about the FCA and that it cause's a no start like I experienced and was wondering if there was any real way to check this before I fork out $$$ for a CP3. Seems everyone I have asked about this states the pump wouldn't just quit like you shut the engine off and to double check the FCA since I get nothing from the pump when cranking it. Anyone have a suggestion as to how to test this switch besides unplugging it?
Thanks!!
