Archived erratic miss and shut off

[Hubert.H]

I have a buddy who is having trouble with his truck. It’s a 02 3500 2wd auto and his problem is with the truck missing and turning off. The motor sputter’s and the rpm fluctuate.

I suspected contaminated fuel, so we dropped the tank and upgrade the fuel system while we were at it. The tank was dropped and we performed surgery on the sending unit to accommodate a draw straw. The tank was indeed dirty and had water. A fass 150 system was installed and we decided to remove the factory lift pump and fuel canister. The fuel hose went from the fass straight to the VP.

Cracked the line’s and started the truck and the same conditions still exist.

I opened the fuel canister to see in what shape the fuel filter was in. When I removed the lid from the canister the housing was filter less. The bottom of the canister has water and debris, not a good sign. He claim’s to have ran the truck filter less for about a couple of days…. . ?

Any help or suggestions would be greatly appreciated (junking it is not an option…. yet:-laf) I've had two people tell me it might be a bad ECM... . ?



I did the key trick to check for codes and they go as follows:



1-P1693

DTC Detected In ECM Or PCM



2-P0219

Camshaft Position Sensor Overspeed Signal



3-P0230

Transfer pump Circuit Out Of Range



4-P0341

Camshaft Position Sensor Signal



5-P0254

Fuel Injection Pump Fuel Valve Current Too High



6-P1690

Fuel injection pump CKP Sensor Does Not Agree With ECM CKP Sensor



7-P0370

Fuel Injection Pump Speed/Position Sensor Signal Lost



8-P1691

Fuel Injection Pump Controller Calibration Failure

First off... . write down all codes and clear them to see which ones pop up. Those will give you a better idea of what you need to look at. ALSO use a scanner... that key trick sometimes dont show all codes.



Dirty fuel tank + NO FUEL FILTER = ECM prob in my book!



Never rule anything out though... . you just need to test and prove what the prob is. BUT finding no filter installed and the truck is acting up, my though would be damage to the VP as sensitive as it is. AND maybe injectors... . thoes are some small holes that can get clogged.



If it was my truck, i would clear codes. See if any popped back. Pull the injectors and have them popped. Then i would go from there.



Does the Tach work all the time? When my cam sensor went out... i had low power and no Tach... but the truck ran.



With all due respect to your friend, if he ran his truck with no filter on propose, he doesn't need to be driving a diesel... ... . I hope he doesn't treat everything like this in his life or I would bet he has a family the size of Wilt Chamberlain's! haha.....

Thanks Dan,



Yes, the tach works all the time. When you start it, it idles normal for about a couple of sec, then it starts to miss and the rpm fluctuate a lot. By this I mean, you feel the power come and go.



While the motor is running (and missing), the rpm will drop to 0 and you hear engine shutting off by itself. Then all of a sudden the motor comes back on and jumps to about 11-12 hundred rpm all by itself.



Just to move the truck from the driveway, it might require a dozen start ups.

If you get it on the street, the motor will begin to jerk and sputter.

It kinda feels like your driving a transmission that bangs into gears and if this was the case this thing must have unlimited forward gears.



I'm not going to get started on my friend and how he treats his stuff. Then I would need to start a whole new thread just on him. Apparently he’s tired of calling DC and getting no results from it. While the truck was still under warranty, the paint on the hood and roof started to come off and the dealer didn’t want to cover this.



Now if it was the ECM, would I need to reflash it or buy another one?

If I were to find a used one, what would the requirements be? (02, 2wd,auto, SO pump)

 

[Hubert.H]

I will get a scanner and have the injectors checked.

I'll see what the scanner reads tomorrow.



Thanks again,

What's the actual time period?



"He claim’s to have ran the truck filter less for about a couple of days…"



I'm curious as to why this was a good reason.

hey diesel dan have brad call me tomorrow or please email me his cell number again or let me know your email address.



Thanks

I'm not sure of the time period, because he's a truck driver and he's usually gone for about a week. Most of the time, the truck stay's at the truck yard sitting for week's sometimes.

I"m not sure but I beleive he told me once that the filter had so much debri, that he had to take the filter off so he could make it home.

Hey man i would give one thing a quick try to see if you can clean the system after you install a filter. I had some issues with things one time and it seemed like i was having a small miss and way underpower so i added "Diesel Fuel Catalyst" from Redline in about ten gallons of fuel and it was an amazing diffrence. It seems lately i need to run that about every 8,000 miles or so to keep the injectors and VP clean.

Sounds like you might have more of a problem but this might be a $6 trick to try at first

 

[mopars1]

Sounds like it could be the crankshaft position sensor may be dying.

You can also power the VP separately from the ecm to see if it is indeed an ecm problem or a pump problem. You disconnect the pump harness. If you look at the pump pins there will be three together like a triangle and then there will be six together. You want to supply a ground to pin 6 which is in the group of six pins. You would supply 12v power to the number 7 pin.



If you want you can email me -- email address removed -- and I can send you a picture of what the pins should look like.

I'm not 100% on this but I think the 01-02 trucks only have a camshaft position sensor... ... . ?

It might be the 98. 5-99 or 00 that have both a cam and crankshaft position sensor. If not, someone please correct me.

 

[rkressg]

01 and 02 have cam sensor.
If you have small hands and about 6 universal joints, you can change it with out pulling the VP44. Unfortunately, my hands are too big to do it, but if you get someone small, they can do it. The Cam sensor is just in front of the VP44. Use a mirror, you can look up and see it.

Well, I finally started the truck again just to move it. It started right up with an occasional miss but nothing as bad as before with the dirty fuel.



Drove off the driveway and once I hit the street, the truck wouldn't miss and drove just like new. I must have gone out for about 4-5 miles through traffic lights, stop signs and everything went flawless.



Then my buddy told me to go pick up a dirt bike about 8 miles from the house, since it was running so good. While at a traffic light, we were talking about how good the truck was running and how much the Fass system really helped clean all the fuel. While we were at the light the truck shut off with out any warning.



Then all hell broke loose, it's like the truck went into ***** mode. It would shut off while driving down a main street, buck and jerk. I couldn't leave the motor idling at a light because it would shut off. When taking off from a light I had to hold the rpms at 2000 in neutral and throw it into drive.



Basically, I'm starting to think that this is an electrical issue. If the contaminated fuel did something to the injectors or pump, then it would run bad all the time. I have a HRVP on the way but I think it's not going to solve anything.
