looks like I can't get him out this weekend ether. should I just throw a crank sensor on it and try it?

 

any ideas fellas only code it's throwing is glow plugs it's been throwing that since 06 and always ran fine

 

im getting a guy out to hook a scanner to her sat ill update with the findings, i need at least 1,450 psi on the rails for her to fire right? anything else i should check when shes hooked up

 

yes. if it reads in mpa then that would be 10 mpa

 

ok like i said i'll know this weekend whats wrong with her if all goes as planed, if i have to get a new CP3 should i run a LLY fpr with EFILive? or just a LB7 fpr also im looking at tuning/mods here soon after its running what do you guys like/run reliably? id like to be on the highest safe output i can get on a a stock tranny i dont want to tear it out or limp it. thanks guys

 

there is nothing truly beneficial using the LB7 regulator over the LLY except that the LLY one can usually be found for a little less $$$. some people use the LLY regulator because it can be tuned for more fuel for those guys looking for more HP

usually without any programming the LLY regulator in a LB7 will cause a lope in the idle and possibly a CEL if it is bad.

if you plan on having it tuned with EFI Live then go for it.

PS: i believe i have an LLY & an LB7 regulator in mine right now (duel CP3s)

 

if i need a CP3 ill probably order this one and send my core first

Merchant Automotive - Duramax Injection Pump LB7

also i want to tune it but nothing extreme what would you recommend all my "buddys" are retarded they say make it roal coal i dont want a cummins i want clean power and reliability any thoughts? also im want to do a EGR blocker plate or delete soon i hate the idea of it running on its own exhaust

 

Merchant Automotive is a good place, i have heard many great things about them.

for me, i have always took a gamble with eBay http://www.ebay.com/itm/YJ001-2003-GMC-SIERRA-6-6-DURAMAX-TURBO-LB7-DIESEL-HIGH-PRESURE-FUEL-PUMP-/151158708512?pt=Motors_Car_Truck_Parts_Accessories&hash=item2331c2d920&vxp=mtr so far i have had good luck but wont recommend it for everyone.

with a stock transmission i would not do more then about 90 HP over stock. the transmission's life is cut quickly above that. some can get away with higher but most wont. 90HP is even pushing it. for a transmission "safe" tune i would go with a 50 HP tune. if you tune it with Efi Live you can have the EGR programmed out and the fueling properly remapped to provide clean HP. i agree with you, rolling coal is not cool.

 

all rolling coal does is wash ring and wast turbos. you said so far youve had good luck how meany have you bought? and do you think a shop would charge less to EFI live it?

 

not to mention waste fuel and ****-off environmentalists which in turn enforce stricter smog laws.

i bought two CP3s and three CP4s from eBay. one CP3 i have in my truck as the 2nd pump and the other as a backup. all of the CP4s where new. paid no more than $100 each and saved thousands.

not sure on the price of tuning at a shop as i do all of my own tuning
