Slow Starts - Diesel Forum

This is only my second post so forgive any unattended mistakes please.My january o5 does not want to wake up in the morning. I have 8000 miles and for approximately the last 2000 miles the first start of the day it lacks power no real surging or missing or anything except a less responsive pedel. It does not matter if i drive 10 or 200 miles on that first start it remains that way. Second start of the day it comes allive the power is back and remains that way the remainder of the day. Would a bad EBP or IPR or any other sensor only be off on the initial start? Also, outside temp has not ben an issue. And It did it with and without my EGR plugged in. Any thoughts would be greatly appreciated. Thank you in advance. [img]/ubbthreads/images/graemlins/shrug.gif[/img]

My problem now seems to be at various times not just the first start. If this occurs with and without the egr plugged in does that rule it out as a problem. Today trying to maintain speed up a decent hill I beleive I got the Turbo fart. I run the predator others have reported this with the sct. I have 7000 miles. Time without my truck cost me lots of money and without trouble codes I am probably looking at a day or more down, if any one can focus my ford tech via me I would greatly appreciate it.

Weird. Mine starts sluggish, but I always ascribed that to things needing to get warm, and I never whale on it when it is cold. But after a fem miles, it becomes responsive.

I have heard of bad pedal sensors. What I mean is, your accelerator pedal is not connected mechanically like they used to be. It's electronic. But that would't explain why the 2nd start is ok.

Have you removed all your extras (Predator, etc.)? Does it still do it? If so, take it to your dealer and let them deal with it. If not, call Predator and tell them to fix it or send you a new unit.

Try the "return to stock" 1st and post.

Thanks RL,
I will return to stock and repost. I know what you mean about warming up, But sometimes it actually feels more responsive cold. The 6.0 warms up alot faster with the egr hooked up, with it off its like my wifes 02 7.3 Excursion. I appreciate your thoughts.

When I picked mine up from the dealer after they worked on it all day, I jumped in, started it, and tried to drive away.....HUGE mistake. It was so gutless, I was ready to go back to the dealer and ask ***. [img]/ubbthreads/images/graemlins/shrug.gif[/img]
So, I drove around slowly for awhile, and after it warmed up, she was herself again. (I always let it warm up for about 10-15 minutes everyday before I drive it)
An yea, it was dead pedal, no boost, no power. I should have had the orange triangle on it.(Slow farm equipment) [img]/ubbthreads/images/graemlins/grin.gif[/img]

Hey yall,
This AM I returned to stock and my initial impresion driving arround a while the first start was good and the pedel had response. The warm up thing is not an issue, ive noticed this 150 miles down the road and i sure hope its warmed up by then. Tommorow I have a good 200 mile trip and will have more feedback. Is it possible they(diablo) don't have the 05 figgured out as well as they think? [img]/ubbthreads/images/graemlins/shrug.gif[/img]

Hey R.L.,
At this point in time I am pretty disgusted with myself for putting out 400.oo for the predator, my truck ran absolutely beautifull this morning. First and second start both ran the same and both were strong. I had too let off at the top of hills (75mph) to keep her in check. The peddle response felt great all day long (200 miles). Now I have only ran the economy 65hp tune no others but unless today was a fluke I would say it detuned 65 horses not added. Why would my 05(Jan build)be that different from what they advertise? I feel pretty lame thinking it was my ford when essentially it was me. Any suggestions on how to handle my tunner would be appreciated.

One thing that might, and I say "might" be an issue is whether you have the right version of software on your predator for the flash in your truck. Ford is a real pain in the ass because they have multiple reflashes for all of their trucks, which means unless your Predator (or ANY tuner, which might explain why some SCT's are not acting as advertised) is matched exactly to your flash, it may not work right.

I would call Predator and ask them to show you how to determine (a) the flash on your trucks computer and (b) how to tell if the version of your Predator is correct. Tell them that if they say all is correct that you will be returning the Predator for your money back. The acid test that you gave is that it ran good when returned to stock. That means the sensors and hardware on your truck is fine.

This one sounds like it is a Predator issue. If it is not the correct tune for your Predator, you can download it from their website or one of their tech's can email it to you. then you use a cable to connect your Predator to your PC and it allows you to overwrite your Predator.

Good luck, and keep us posted, RL

R.L and all,
I called Diablo, I have the latest update r76 and it "should make power" which I assume means more then stock and as they advertise through the whole powerband. The phone tech advised me to try one of the other tunes (45 or 100 hp) and see what happens. I understand the theory of differentiating between a single tune and the whole tuner but I am a little liery of "seeing what happens". what do you think?
thanks

Had no problems with my diablo. I just switched to the SCT Custom and may go back as I can't pull w/ the SCT Towing mode. It sneezes between 55-65mph w/ 20ish psi of boost. I normally tow at those speeds. I think it's due to the shift points. Hopefully Innovative will help me out. I want to do some more testing then I'll call. BTW I hope no one is paying $400 for a predator. You can find them for $300 pretty easily. Not bagging on anyone but msrp is only $349 or so.

richgann,
I think it may just be my truck,(when was your 05 made?)My truck does seem to have a whole you fall into about 50-60 if you let off it just prior, durring or after, I usually go right through it. This actually seemed worse tuned then stock. If the 65 dont work will the others, with no harm no fowl? [img]/ubbthreads/images/graemlins/shrug.gif[/img]
