Engine/Transmission (1998.5 - 2002) Now power for the first mile

[LHepplestone]

Hi, I have a friend with a 2001 Cummins. It is the same truck as mine. He is having a problem when first cold starting it. It starts fine but then has a power problem for the first mile. This is not all the time, maybe one out of ten cold starts. The truck won't go over 30 mph. Won't rev, no smoke, just no power for about the first mile and then everything goes back to normal and runs great. He has a Edge EZ, 4inch Exhaust and a K&N filter. Any help on this one would be great.



Thanks, Lee

My 2001 acts the same way.

 

[PatrickHenry]

my 01 is doing same thing. I can turn off key and back on again and it will go for about 10-20 seconds before what I call a dead pedal. Once truck warms up it seems to stop and run allright.

it has been doing this for at least 20,000 miles, seems to me if it were vp44 it would have already quit. straight pipe and edge ez are the only mods on truck. Any input would be appreciated.

My truck runs fine during 60+ degree weather. When colder it acts just like a gas engine with a choke . . . dead pedal. Once it warms up it runs strong. When temp is around 30-40 deg, it takes over a mile before it runs ok.



I have found that I can turn the key off momentarily, then turn it back on and it will run ok for a while.



The knee-jerk reaction seems to be replace the VP44. I don't buy it.



I purchased a new lift pump and move it toward the tank. No improvement.



Filters are changed regularly.



I did replace the thermostat because of slow warmup, it was stuck open.



What I have not done is install extra gauges. I am going to do that next.

Might be the warm up thing on the 24 valves that when the motor starts it runs on three cylinders(i think when its 32 degree's or lower outisde). Not to sure what its called or if thats your alls problems. Someone else on this board knows more about the 3 cylinder warm up idle, figured I would mention it, hope someone else will chime in on it. My 01 doesn't have all the symptoms your all 01's have. Hope you all get it worked out.

 

[PatrickHenry]

looks like no one has an answer to our problems.

maybe someone can chime in and help. weather is getting colder and it

seems to get worse when cold.

 

[dslmacdown]

Has anybody checked for codes?

Checking for codes

 

[PC12Driver]

MAP sensor? Without "seeing" an increase in pressure the ECM won't add fuel. Maybe the sensor is getting a little sticky in the cold. And if it sticks, it won't throw a code since the voltages will still be in the expected range...

mine does the same thing in winter, sometimes the odvious and simplest answer is the right one, these are a huge chunk of iron, it takes longer to get warm when it's cold.



an easy test would be to plug in the block warmer and see if it helps the next morning.

 

[JaySummers]

i'll have to chime in on this problem with the cold run also. I have a 2001 that does the same thing for the first mile or so. Mine does show a "soft code" of P0216 which I understand from everything I've read so far that I need to replace the injector pump. I'm just not yet convinced that this is the whole problem since the truck performs so well when it's warm. I have noticed that during really cold mornings (30 deg) the one mile is turning into two miles. I sure hope someone offers a bit of wisdom soon. thanks

HELLO? Mine just started doing this during the last four months, 150k miles on the truck, bought it new and no . . . . plugging in the block heater does not help either. . . nor did a new MAP sensor change anything. Key Code=P1693

Well I'm going to try and put dielectric grease on map sensor connections and see if it helps.

Dephnice and others,



Is there are other codes. p1683 is just a PCM code that gets thrown when there is other codes too. Its called a "Companion code. " Was there any ECM codes thrown.



When u run the key code check routine it will run through the PCM and ECM for codes. At the end of each it will say PCM Done and ECM Done. There should be another code in there that will be specific to the problem. I have never seen a companion code with out an actual fault code too.



Also the symptoms described in the above posts, is EXACTLY how my VP started to act when it was first starting to get bad. In my opinion, if you have thrown the 0216 code the writing is on the wall and it is just a matter of time before the VP quits (or gets bad enough for you to take it in for replacement) I ran mine for about 5 months after 0216 showed up and took it in for a new VP under warranty after I was getting 3-5 Dead Pedal episodes a day and it started having hot start problems. Some VP's go quick others cling to the side of the grave for a while before giving up the ghost.



BTW not a single problem in the 1. 5years/25k miles since new VP.



Hope this helps, even though its not good news,

Well the dielectric grease made no difference. The codes are 0500 "no vehicle speed sensor signal" and of course the dreaded 0216 "Injection pump timing failure" I guess that my truck's pump is one of the ones that don't just go dead. But it may have something to do with the 0500 code because once truck is over 60 mph it runs fine but under sixty it won't accellerate unless you let off pedal and get back in it.

Many thanks . . the only code I get is P1693, then after the PCM check routine is 'done' . . . p done, the mileage comes back up on the display.

I was afraid the problem was linked to the vp44 but because of good performance after the engine warmed up I thought that it might be the intake air temperature sensor that was sending a false signal to the pump. I checked the engine coolant sensor and it was within specs according to my Haynes manual. I do not have any specs for the IAC and the book stated that Dodge never published any. JCyrbok - Did anything else get changed when you had the pump replaced?

 

[JCyrbok]

dephenie,



Does it ever flash ECM Done? It should do this for both the ECM and PCM.



It takes about 15-20 seconds for my truck to go though this sequance. U only have to do the key sequence once and it will run through both. Help this helps.



JaySummer,



Nope only the VP got changed. It had a new filter aprox 1 month eariler and a lift pump at the same time(my truck lost three lift pumps in about a year, which is what helped the VP die). It got a FASS about a month after the VP.





Hope this helps

No, never does the ECM code. Only get the PCM done message. Thanks dp

 

[JaySummers]

Thanks for the info. Any suggestions on where to get a pump. On e-bay they all look to be in the $1000-$1100 range.

Hey Guys,

When I lived in upper NY My 2001 never gave any problems starting, even when not plugged in,I had 50,000 plus on it .
When it was cold enough I would run the grid heater cycle 2-3 times depending on how cold it was and how long it had set.....
