    My dads 2007 Toyota Tacoma v6 4.0l is missing on cylinder one. Have replaced injectors plugs and have moved the wires around too it is only missing on cylinder one. Any advice.

    Pull the plug for that cylinder. While it's out check the compression. If it's good, install new spark plug and swap coil packs with another cylinder. The miss should move to another cylinder if the coil pack is bad. Sounds like you've already eliminated the injectors. If there is no compression issue then maybe a wiring harness problem?

    What fault code are you getting? I think an open injector or coil pack will set a code?
