2000 Blazer New Project
So the fuel pressure sensor Code PO452 went out and I had to replace it. It is located on the fuel pump. You MAY be able to remove this by only lowering the tank, however when I pulled on it, it broke off. So I had to drop the tank and pull the pump to get it out. The seal on the pump was stretched but I couldn't find a local spare so did the best I could to put the ring back in. Went to fill it up and the moment the pump clicked off full, I heard a spill. The pump leaks.... Ordered the replacement ring from amazon, now to burn down the tank and do it all over again. FML

Got the new seal in so I dropped the tank. Decided to completely drain and wipe it down. I have to put a tiny bit of oil on the seal so that I could get it in. If you have to swap the fuel pump, I recommend doing this. It makes it a million times easier. While the tank was out I decided to swap the passenger leaf spring finally. The shackle bushing was completely shot on this side. It fell out as soon as I removed the bolt. At least it wasn't seized like the other ones. I took a torch and melted out the rubber from the metal cup. Cleaned it with paint thinner, greased it up and pressed the energy bushing in. I also did the same thing to the driver side since I never got to that bushing before on account of the fuel tank and charcoal canister being in the way. The ride is WAY smoother now. And I am getting a LOT better mileage with the new fuel pressure sensor.
So I had issues with the abs activating whenever I would hit bumps. I also had vibrations at about 55. I decided to Finally replace the passenger side hub. It was on $55 on Amazon
Worth every penny. All those issues are resolved. I'm about to order the driver side now. Replacing the hub was SUPER easy took 10 minutes.
I also just got the weld for the eyelet on the driver side lower control arm redone and sided the arms for the rear sway. Makes a huge difference having both hooked up again. Love how it rides now. I also just finished the cai. Here's the pic.
