    check the spacing on the plugs and if you used aftermarket try toyota denso plugs, our trucks dont like aftermarket

    also is it getting fuel? have you tried cleaning the injectors or much easier replacing the fuel filter or checking the pump pressure?

    make sure the plugs you bought have the two electrodes on them or two prongs whatever they are....
