2000 F350, 6 speed, 175K on it.

Like this morning, had the truck hooked to the gooseneck trailer, went out and I get a short glow plug duration and no start, another time key and no start. Then I get proper glow plug and it fires and ran so that I made it about 200 feet down my drive and died, it would fire and die about 500 feet down the drive, it does the same thing even when warm. Its not a glow plug issue because it will do this when the truck is warm.

So sometimes it flat out dies and re-starts just fine. Other times I get a no start, no smoke situation. I know that it isn't going to start because I get a really short glow plug duration with no smoke even if the truck is warm (doesn't need glow plugs to start).

I have swapped out 3 CPS's and it happens on all three (1 gray, and 2 black). What sensor would cause a short glow duration, no start and die while running after all day issue? It also had a dead pedal sometimes after it restarts with this issue.

Then I have days where I don't have an issue and runs great.

I don't have a code reader, I am going to need one to help me with this truck as this is my first real issue. What should I buy?

The WTS light is controlled by the PCM. It uses data from the Engine Oil Temp and the Ambient Temp from the air filter box. The WTS light is nothing more than an indicator for you, it does not have any effect to the glow plugs being on or not. The glow plugs can be on for up to 120 seconds depending on oil temp and ambient temps. You will also get a WTS light when the engine is warmed up, but your glow plugs will not be commanded on.

You may be having a PCM issue, You have a Edge on it, have you tried removing it to verify that is not a problem?

Random shutdowns can be caused by lots of things. Most likely not a sensor doing it though. Usually it has to do with oil pressure or fuel, but if you have a PCM or an IDM that it on the fritz, it can easily shut down the engine too. It is hard to tell without running diagnostics on it.

Thanks I will keep this thread going as I work through this issue. I am going to remove the Edge today and see if that is the issue.

I am also going to check and see if I hear the fuel pump is running as I have noticed that it seems like I can't hear it run when the key is turned on before I crank.

What should I get for a code reader to help me through this. It does set a check engine light but goes away with susiquent starts.

Autoenginuity is what I use, It is far more than a code reader as it allows you to check live data and perform tests. At $360 (plus you need a laptop) it is not cheap, but worth every penny IMO. Most OBD II readers will not work as they cannot pull manufacture specific codes, which will be almost every code you will have. You have to get the Ford Enhanced bundle, but it will read generic codes on all other vehicles.

Well a little more information on my no start, dying issue.

I had a friend of mine swing over and he was unable to read the ECU with AutoEnginuty.

I used my bluetooth adaptor and Android torque and was also unable to read the codes from the ECU but appeared to have communication.

It is still the same failure mode, if I get a short glow cycle it will not start. If I get what I consider a normal wait to start it will start, run normal with a slight dead pedal and then about 30 seconds later die.

Its almost as if it has a securty system in it that 30 seconds after starting it always stumbles and then may stumble again and dies completely.

I have changed the CPS, ICP and have removed the edge with additude from the wiring harness. I have also unplugged the ICP and the back pressure sensor on the front of the motor and it is still the same. No start, start and then dies.

Since it runs for 30 seconds is it possible that it is the ECU?

Thanks, I have a video I will put up tomorrow because I get erratic behavior also when the wait to start light is on... like the tach jumps (not when trying to crank) and almost like a recycle of the key.

Does your friend have the Ford Enhanced version of AE? Did you switch the communications configuration to J1850PWM? Automatic mode doesn't seem to work on the power strokes from what I have found.

Have you checked the oil ?

are you due for an oil change ?

 

[Westro]

I did check the oil and add about a quart, it is not due for an oil change.

could a bad rail mounted fuel pump cause this? I also pulled my ICP and it had some oil in it, so I replaced it with an older one I had. truck still acts the same even with it unconnected.

 

[Westro]

Found out the ECU was loose in its attachment. So I reseated the connectors and everything seems to be running as it should. Hopefully I was just having ECU connector issues.

 

[woodnthings8]

Good deal! Thanks for following up.

Hmmm...my 2000 Ex with 175K started something very similar this morning. Quit in the driveway maybe 2 min. after cold-start. No restart. Key to "Off" and got a restart and repositioned to parking. Later in the afternoon, fiddling with it, noticed if I turned key to "on" and let it sit awhile, I'd get a crank with no attempt at a start. If I turned it to "off" and then went immediately thru "on" to crank it would start. Run a while at idle and cut out. Nursed it up into the shop and started running searches here to see what's what. Haven't otherwise messed with it. Know oil level to be good, 2500 mi. since change. Haven't looked in on HPOP yet. It was very similar to a few years ago when the CPS went bad at around 100k mi...and now with 75k on this one...perhaps?
