    Another 454 Vortec Build Thread - Documenting, Q&A, Help

    Finally had time to get the new fuel pump installed into the bucket and wired up. Once this is installed this weekend that would make for a brand new fuel system, and brand new ignition system! Have to pick up an air filter that I noticed missing as well. Here's some pictures of what I was...

    New injectors, plugs, wires, FPR, Dist cap and rotor installed! Ran much better but still getting a little chug and backfire so I pulled the pump yesterday and am installing the new one this week. With an entirely new fuel system and mostly new ignition system this thing should run much much...

    Interesting considering they have the same part number as the stockers. They look like hell. Possibly didn’t even need replacement but new ones are in so we’re running the new ones lol

    Want to Learn To Tune - Need help getting started

    this is true, but everything I have read says the 0411 swap will give me much more control for my future mods as well as dialing in the stock tune much better for better driveability and maybe even a little more ponies and fuel mileage. Though I am not countin on the fuel mileage lol.

    Want to Learn To Tune - Need help getting started

    While I keep my other thread going, I want to start a separate one for the tuning aspect. I want to learn to tune my own truck. As time goes by I will be adding mods and changing things so there will be the basic tune when I get the truck running, and then tuning as I upgrade the exhaust and...

    Ok I see, vacuum line was rotted and replaced I was looking at the fuel rail not realizing what it was. We’re all set on that lol. You should see my injectors they look terrible, new ones came today along with new quantum fuel pump.

    It was pretty rough, vacuum line makes more sense I’m retarded. I did replace it with fuel line though because I’m dumb. It is 26 yrs old and had heat contending with it so no surprise it’s deteriorating.

    Imagine my surprise to see a high pressure system have a 2 inch piece of fuel like hose between the fuel rail and FPR. It was severely rotted. That’s fixed as well as the new FPR. Injectors and fuel pump next weekend!

    Update: Got the upper intake off, need to shop vac badly lol there’s leaves everywhere! Injectors look stock, will pull those and FPR off today new parts come tomorrow. Fuel rail looks to be in good shape though.

    You guys are giving me great advice here but I’m not 100% certain which one to follow. I’m going to just replace the injectors as they are stock with 200k miles and they are problematic, and also the fuel filter and FPR with a GM stock one, as well as replacing the fuel pump. I’ll be checking...

    It went up to 58 psi, test wanted to see 62 psi. Anything under 62 it directed me to FPR. Implication is FPR is working but not fully regulating. My guess is the injectors are actually the real issue causing leak down. My wife stated in the first test it jumped to 62 psi with key on then...

    Ok tested following alldatadiy guide. Pull pressure was only 4 psi low on the rail and also 4 psi low with return line pinched off. With that data alldata still says FPR so I’m doing that this weekend. In both instances pressure dropped about 1 psi every 5 seconds so injectors are not ruled out...

    10-4 that helps a ton! I seen 2 soft lines going into hard lines that were stacked on top of each other and tried both, will look a little more closely this time around. I get very little time to mess with this during the week, and of course the person limiting my time is also the one saying...

    Ok key on test at rail is 54 psi and drops about 1 psi every 10 seconds. I’m not sure which line is the return line so I tried both. 1 line psi hits 54 and slowly drops, other line psi hits 58 then slowly drops. Possibly 1 psi every 30 seconds.

    I’m going to test the fuel pressure tomorrow with a jump since my battery is dead dead and if it tests ok then I will have to buy tools to test compression.

    Another 454 Vortec Build Thread - Documenting, Q&A, Help

    I haven’t tested it but 99% certain it’s good since I drove it like 10 miles, but it did run like crap and backfire occasionally so would be good to test but I don’t have the tools for that. Also this thing is draining batteries anyone know best way to look for battery drain? I don’t even know...

    Beautiful thank you sir I have a large c clamp that might do the trick I’ll try this tomorrow and report back. As far as the fuel rail goes it was 54psi and dropped 1 psi every 10 seconds I believe

    How do I pinch off the return line?

    Another 454 Vortec Build Thread - Documenting, Q&A, Help

    On it sir I’m not ignoring anyone, in 3 years nobody has gotten this thing to run and I have info that the injectors were never done. I’ll look for the spot for the return line and test I’ll have to see how to do that.
