Re: Van Will Not Shut Off
I don't know how the Ravelco is wired in, so this may not be relevent....
But on a stock van, I don't see how this could be anything other than a faulty ignition switch. Without RUN power from the ignition, the PCM won't get power, which means the FICM won't know the Crankshaft or Camshaft signals, and therefore the injectors simply won't work. Not only that, the FICM also gets a voltage signal directly from the ignition switch (in addition to main supply from the FICM relay, so I presume the ignition voltage circuit is a safety in case the FICM relay fails).
So unless the Ravelco modifies the power source for the PCM and FICM-ignition-signal, its the ignition switch. I would think however the the Revelco would simply interrupt the power supply, and not supply it from another source??? (pure speculation... if they do bypass the ignition switch completely, bad on them....)
The only other possibility I can think of is the wires in the steering column are chaffed, and are effectively bypassing the ignition switch. This shouldn't happen though unless the stock harness has been unwrapped allowing excess movement and rubbing.
