Can someone tell me whats wrong with this car bomb script?

I am making a new game that has cars that are placed into lighting, then when a user clicks the pad he chooses which car he wants. I have the car spawning and driving working, but when I go to the bomb shop and put a bomb in my car and then activate the bomb, it makes the bomb blinking light and explosion near the place the car spawned. My goal is to get it to explode exactly where the player is sitting so he dies. Can someone take a look at the script and find out why it is placeing the explosion and blinking light where the car spawned? Here is the script:

local currentBomb = "None"
local radius = 25
local multiplier = 3

script.Parent:WaitForChild("HasBomb")
script.Parent:WaitForChild("BombArmed")
script.Parent:WaitForChild("Essentials")
script.Parent.Essentials:WaitForChild("BombLight")

script.Parent.HasBomb.Changed:connect(function()
    if currentBomb == "None" then
        currentBomb = script.Parent.HasBomb.Value
        coroutine.resume(coroutine.create(function()
            while currentBomb ~= "None" do
                wait(2)
                script.Parent.Essentials.BombLight.Light.Enabled = true
                wait(0.2)
                script.Parent.Essentials.BombLight.Light.Enabled = false
            end
        end))
    elseif script.Parent.HasBomb.Value == "None" then
        currentBomb = "None"
    end
end)

script.Parent.BombArmed.Changed:connect(function()
    if currentBomb == "PrimeNRun" then
        for i = 1, 20 do
            script.Parent.Essentials.BombLight.Beep:Play()
            wait(1.4/i)
        end
        local e = Instance.new("Explosion",Workspace)
        e.Position = script.Parent:GetModelCFrame().p
        e.BlastPressure = 0
        e.BlastRadius = radius
        e.Hit:connect(function(part,dist)
            if part.Parent:FindFirstChild("HealthVal") and ((part.Name == "Primary" and part.Parent ~= script.Parent.Body) or part.Parent.Name == "") then              
                part.Parent.HealthVal.Value = part.Parent.HealthVal.Value - ((multiplier*2*radius/dist)^2.5)
            elseif game.Players:GetPlayerFromCharacter(part.Parent) then
                part.Parent.Humanoid:TakeDamage((multiplier*radius/dist)^1.5)
                if part.Parent.Humanoid.Health <= 0 and (not part.Parent.Humanoid:FindFirstChild("creator")) then
                    local tag = Instance.new("ObjectValue",part.Parent.Humanoid)
                    tag.Name = "creator"
                    tag.Value = script.Parent.OriginalOwner.Value
                    if script.Parent.OriginalOwner.Value:FindFirstChild("KillCounter") then
                        script.Parent.OriginalOwner.Value.KillCounter.Value = script.Parent.OriginalOwner.Value.KillCounter.Value + 1
                    end
                end
            end
        end)
        script.Parent:BreakJoints()
        game:GetService("Debris"):AddItem(script.Parent,10)
    elseif currentBomb == "Carsitting" then
        script.Parent.Essentials.VehicleSeat.ChildAdded:connect(function(kid)
            if kid.Name == "SeatWeld" then
                script.Parent.Essentials.BombLight.Beep:Play()
                wait(0.1)
                local e = Instance.new("Explosion",Workspace)
                e.Position = script.Parent:GetModelCFrame().p
                e.BlastPressure = 0
                e.BlastRadius = radius
                e.Hit:connect(function(part,dist)
                    if part.Parent:FindFirstChild("HealthVal") and ((part.Name == "Primary" and part.Parent ~= script.Parent.Body) or part.Parent.Name == "") then              
                        part.Parent.HealthVal.Value = part.Parent.HealthVal.Value - ((multiplier*2*radius/dist)^2.5)
