    LB7: Need some serious help diagnosing fpr/rail issue

    Does anyone know what the correct voltage should be on the 2 wires that go to the FPR? Also does anyone know what else tells the ECM to send that voltage? Map sensor/baro sensor/fuel temp sensor/MAF sensor are the ones I'm guessing. Can one of these sensors be sending the wrong signal to the ECM...

    LB7: Need some serious help diagnosing fpr/rail issue

    It may be bad working somewhere but I don't think it's wiring to the FPR though as I don't have the proper voltage coming out of the ECM. Tried 2 rail pressure sensors too

    LB7: Need some serious help diagnosing fpr/rail issue

    :hug: Hey James yea it's been a while. Congrats on the little one! Still on here lurking every day but had been pretty discourage with my truck for a while because I can't seem to figure this thing out. Tried unplugging the lift pump with no changes to rail pressure. The regulator isn't...

    LB7: Need some serious help diagnosing fpr/rail issue

    Hey guys been a while since I've messed around with my truck but it's time I dive back and put these issues to bed because I am at a loss on what to look for. A little back history, after getting out of my mess of a used built motor I bought, I found a motor from a member on here out of a...

    That's going to be a sweet build. I'm digging the lifted 22.5 wheeled truck you posted. What did you pay if you don't mind me asking?

    LB7: Twin lag?

    Keith, it's definitely tuning related. When I put my twins on and the truck was tuned for my single stock charger it reacted the same way you are describing. Slow to spool but once it did it took off like a rocket ship. Once I got it tuned for the twins it was a whole new truck. Give Tony at...

    Much needed attention

    James you did a great job. Truck looks awesome after getting some well deserved cleaning! Im going to let the cat out of the bag on my latest favorite detailing cleaner(Which isnt even an automotive cleaner). I cant say I discovered this and I have no idea how long people have been doing this...

    Bed support rails rotted.....

    When I was at the moonshine mans house a few weeks ago, his brother was there with his 06LBZ and he had the same issue with the rails rotting out bad. He showed me the pics that him and Tony took. His truck is real clean and not a spot of rust anywhere on or under the truck. He took it to the...

    Territorial Dog Help.

    There are some interesting theories of dog training in this thread. Not saying that they are wrong or haven't worked, but I dont agree with some of it. I got into training my dog and did a lot of research on this website and found it to be pretty useful. Just read through some of the articles...

    Long shot

    Just something simple and stupid to look for that bit me in the ass. Make sure all the points where the alt bracket touch the block are clean and the bracket and alt are grounded properly. These trucks are really finicky with grounding issues. Just a quick way to check it is run jumper cable...

    Possible Triples Setup, will it work?

    I guess now that Trents not in the sport anymore I'm allowed to talk about the specs on my setup. James, Evan's right they are two S360's not 66's over a stock batmo wheeled ihi. Even on stock max effort fueling they spooled wicked fast. Made short work of the stock motor as James said though...
