its sooooo tough waiting to hear back from john, but from every one thats got a pump from him i hear its well worth it, i cant wait to be in that group...

voice mail was full again when i tryed to call.. darn east coast guys must be filling it up every day before us west coast guys get up.

 

i finally got ahold of some one at II and think i have it figured out.the fitting on the back of the pump that doesn't do anything, is the dual feed fitting. so i can run my dual line after all, and that in turn will bypass my relief valve which i am sure is most of the problem.i am also sure that i will need to get my injectors in very soon.so i will try to get the second line in and see what happens from there.thanks to all who helped me out, and any one who was following for reference. i will update soon.

 

update, i did my dual line tonight, and my truck is louder, and still falls flat on it face when i try to give it, or at wot.
i can start to pull hard, shifts into second, then builds some more boost then bam nothing, boost goes to zero, no fuel i am guessing, rail gauge read around 25,000psi, with the low gauge reading around 10-14psi
it seems that fuel is getting there, but the truck won't take it. with the dual line the relief valve is now doing nothing. i really don't know what to look for next. would my stock injectors be holding me up?
i am getting frustrated!!

 

Stock injectors with a stage 3 pump?

 

pullin hard seems to have the cart infront of the horse..

 

you get sh !t on that way!!!!
yes stock injectors, but i have new tips, just waiting for my cores to be done, checked and cleaned before install.
i did talk to couple guys at II today, they are sending me a new FCA
i will try anything right now, to figure out this problem.
i really don't think its the injectors, i think the computer is being told to shut down fuel some how. never did this before the pump, and i don't think its the pump it self, cause it builds pressure just fine.
anything i am missing here

 

i am at a loss here. i don't know where to look any more. i just switch my old FCA with the one that was in the pump, and same thing, no wot runs, quits, but now since it was day light out, i noticed that i get white smoke out the tail pipe when it cuts out.is this because of the un burnt fuel, or is this another problem? anybody know if my stock injectors would cause such a problem?? when i installed the smarty, that was the only thing the is different in this mix other then the pump.could it be a bad program, or didn't take well and is causing my ecm to do funny things? i did take the smarty out of the loop back to stock.i can't think of anything else.i have good low pressure to pump, and i have good rail pressure, the dual line is in, the relief valve is now not used. it feels just like when i set my egt reading low on the tst box, and race, its just like de fueling, total loss of power, and boost drops to zero.

 

The first place to start chasing a problem like yours is to take all performance adders out of the picture. TST, Smarty and anything else that plugs into an electronic port of any kind, including gauges. Go for another drive and see what happens. If all is good, go back one thing at a time. Start with the ''none performance'' stuff like gauges, then drive agian. Still good, put the Smarty on and drive. Lastly, try the TST. I would also open the TST up and make sure the 7 fuses inside are good and look for corrosion. I know it is a pain, but I would take the TST harness completly off. Cam and crank sensors, too. Don't just use the bypass.

Try these things and update.

 

i did take all programing out, i never took TST harness completly off, but set everything to 0.i just hooked up smarty, and erased code 0251, fuel control accuator,CP3 pump. that could have been because i had it unpluged to change out. i went for a run on #6 , and i can't get over 20lbs of boost, it cuts out.i went through the tst programs to make sure something didn't changed like de fueling at a really low egt, or boost cut off etc. everything there seems ok.i am wondering, if maybe my fuel prerssure sensor in the rail is no good? or maybe i have to un hook it? if the pump was plumbed up[ wrong, would it still work? there is no instructions with that pump, but i know the feed lines are right, no choice there, but the other 2 rubber lines could be in the wrong spot.i will open up the TST box tomorrow to check it out for corrosion, and fuses, i didn't knwo there was any in there.
in stock form, the truck still does it, just takes alot longer to cut out.
the strange thing is that the boost never gets over 20lbs, i roll on it, or hit it, and it doesn't get over that hump, rail seems to be around 20,000psi -25,000psi. it seems to cut out at the 20,000psi, but the gauge moves to almost 25,000psi before it drops.

 

use the bypass for the tst (they had lots of problems with the harness) mine would act up setting everything to zero. Use the bypass or completly remove the harness. That is the only way to get it out of the picture completly.

 

i am going to try that for sure. i talked to guys at II today again, and have a couple other things to try. first is to make sure the harnesses are in the proper order. i didn't know they had to be plugged in a certain order. i believe my EZ is plugged in to the pressure sensor, then my gauge, and it should be the other way around. i am wondering though, what order does the EZ and the TST go, does it matter which one is first?
also, i have 18psi of low pressure feeding the CP3, he said to lower it to 12psi, could be spiking the CP3 in the mid range and telling me ECM to de fuel.
so i guess tomorrow i have some more things to try.

 

With a big pump and stock injectors....I'd remove the pressure box. I had on a Grand Pooh Bah last year and it would PEG the DRB at anything over 1/2 throttle and this was with 62L or Flux 3.3's....with stock program and TST on 2/1....If your FCA is good and your pressure sensor is good then it must be a wiring harness....I had a tranny rebuild and finally found out my tranny problems with early shifting were from a couple of intermittent wiring faults on taps on my PCM...KS

 

well i just switch the wiring ,gauge first then the EZ. i will try that tomorrow, if that don't work i will remove the EZ altogether. they are telling me to leave the EZ on.but at this piont i will try anything.could be wiring, not sure where to look, everything on the TST harness looks ok from what i can see.i will pull it off if i have to.i really haven't beat on the truck for some time, due to winter, cold, and no traction, but i don't remeber this ever happening before the pump install. it makes great pressure, maybe too much. i am going to low my feed pressure too as soon as i can get into my shop, kinda full right now with junk.thanks to all for the comments and advice, i will get to the bottom of this all. injectors are going in to get cleaned and calibrated tomorrow.

 

so tonight i changed the low side fuel pressure down to 10psi, still nothing, then i put the by pass plug on the TST harness, still no fix. i didn't take the front cover off the TST box, looks pretty good in there, fuses are ok.
so i am thinking, that maybe this is not a pump issue at all.
something is telling the ecm to shut down. when i changed the way my rail gauge was hooked up with the EZ, it seems to read lower pressure, i have been watching the rail and the boost, and the one that seems to be consistant is the boost number. it never really gets over 20psi of boost before de fueling. so maybe my map sensor is no goodmaybe my rail sensor is no good, maybe i have a bad waste gate on the turbo, and at 20psi or there abouts, it senses the boost drop at the map, and tells to de fuel.
just before i changed out the CP3, i installed the smarty box, never really tried it until that night when i got the pump done.kept cutting out, so i came back home and put that back to stock. could the smarty have done something to the ecm where it has a glitch, or some sort, cause this problem, or just an ecm failure?
i keep thinking of everything i can possibly think of that would cause the truck to de fuel at around 20psi of boost. the rail gauge reading tonight was around 18,000psi.
any thoughts?

 

ok, tonight after work i took the TST harness out, running only EZ and smarty, still cutting fuel out. i changed the gauge and EZ connections back to where i had them, after talking to II today, i had it right the first time. so now my rail gauge is reading normal. when i get on it, it seems to build pressure, up to about 20,000psi, then it jumps to 25,000psi pretty fast, thats where it cuts out, not sure if it happens before it jumps or as it cuts the fuel it jumps cause it happens too fast to tell. i don't have a separte boost gauge, to tell where my boost is while this is all happening, but feels the same around 20psi of boost, and not much more then that.
so now i am at a total loss, i don't know where to turn or look for next.
any suggestions?
i am thinking this, take all programing out, and re flash the computer , and test drive. it will eithewr cure the problem, or not, rule things out 1 by 1

on a side note, what i did notice today, is the the shift indicator in the gauge cluster is not the same. the square that goes around the letter for park, reverse, neutral, etc, only moves from park to neutral, it does not work or light up on any other gear. was wondering if this had something to do with my problem?ecm clitch? trans problem? something
anybody have this happen or know where i should start????
