I have a 2000 7.3 Power Stroke in my Ford F-350 Dually and it will not start. It quit running last week one morning about a mile from my house. I'm in Arkansas and rarely have any cold-start issues. It was a fairly cool morning, around 32 degrees, and it quit before the motor even got warmed up good. I pulled it back home and just got to look at it today.

The batteries are hot, and there is nothing obvious. I checked the reset button on the fuel pump and it wasn't out. I just changed out the CPS (had that problem on my 2002 7.3 Powerstroke recently) and it made no difference at all. Now I have an extra CPS. I am not showing any codes.

Anyone have any ideas on where to go next? GPR? GP? ????

Thanks for the help!

 

How did it die? Spit and sputter or like someone shut the key off? What do you mean the batteries are hot? This is a computer controlled engine. If voltage falls below 10.5 while cranking you may start to run into problems. Do you know what voltage you have while cranking? Is there any smoke coming out the tail pipe while cranking? Is the oil full? How much have you cranked on it? Is the HPOP reservoir full? What did you use to read the codes?

 

When you turn the key to the on position do you hear the fuel pump running ? It's located on the drivers side inside frame rail about where the drivers feet should be, if you can't hear it reach down there and feel if its running. How much fuel do you have ? Did you check for blown fuses ? Where are you located at in Arkansas ?

 

When it died.... it just quit.,,,just like turning off the key. When the CPS went bad on my 2002 it did the same thing. I don't know what the voltage was when cranking but the batteries have checked out to be good. Haven't checked for smoke when cranking and haven't cranked on it much. It usually cranks up in just a couple seconds. HPOP? I haven't read any codes yet, but there are no CEL lights or other lights showing.

I consider myself a fair wrench but I'm by no means a diesel mechanic so please forgive my ignorance on some of this stuff.

 

I can hear the fuel pump running and I have close to 1/2 a tank of fuel in the truck. Hmmm... I haven't checked for blown fuses. Anything in particular I should look for? I'm located in Hot Springs and as I posted earlier, I consider myself a fair wrench but I am by no means a diesel mechanic so please forgive my ignorance on some of this stuff.

Thanks for the help!

 

dose the wait to start light come on?
if not the fuel bowl heater may have blown the #30 fuse the runs the PCM

 

X2 ^^ you beat me to it

 

Yes, the wait to start light comes on.

 

then check the IRP nut to see if it may have come off.

 

Does the tach move when cranking?

 

Check for smoke when you try to start and if you have none, check and see if you have fuel in the filter housing , look at your filter while your in there. Have you been running through a lot of deep water ?

 

I went through some water the other day when we had all of the bad rains. Do you think that may have caused something to go wrong?

With work my time is limited but I will have some time tomorrow to get back to it. I will check for smoke and the fuel filter then.

 

When you changed the CPS was it wet in the plug ? If so take it back apart and dry it real good maybe with a blow dryer see if that helps. I live up on the nw side of the Rock, we have quite a few 7.3 guys in the Ar Chapter and a lot of us live right around Little Rock, we aren't that far away .

 

The CPS was wet with oil when I removed it. Everything else is dry. The new CPS didn't change anything.

I do appreciate the help. I guess I need to join the Ar Chapter since I have two rigs, a 2000 F-350 Dually (my current problem) and a 2002 Excursion Limited, with the 7.3 PS motor.

Thanks again!

 

How deep was the water and are there any holes in your passenger front fender liner?
