    L36 top swapped 2004 Comp G. The car ran bad, found two plug wires on wrong, fixed that and it idled great for a bit, but had NO throttle response. Put a different throttlebody on, fixed the issue, and it would raise RPMs as I pressed the pedal. Then it just died, and won't start again. No codes, either.

    Definitely can smell fuel on the plugs, getting 180psi compression, and it has spark. I don't know where to go from here.. any ideas?

    2002 Trans Am- 6 speed, bolt ons or something, it's slow.
    2006 Silverado- forged ls2, 4l80e, plate kit, also slow...

    Check the fuel pressure anyways, but it could be a number of things including the fuel pressure regulator, crank position sensor, ICM, coils, grounds, or maybe even something else. Does the ICM seem to have a lot of corrosion behind the coils?

    I swear... every time I make a "help" thread it ends up being something super super simple that I find right after. Somehow the fuel pump line in the tank came off the canister....... Go figure

    Honestly, I'm not sure. It obviously sounded just fine, as it was wired up the right way, it just wasn't feeding fuel. Luck, I guess?
