2003 FX45, 165K miles, with the keyless/proximity-key-fob ignition switch.
I have what appears to be a starter interlock problem.
Recently, and only occasionally, the engine will not turn over when the ignition switch is turned to start. Transmission is in Park, and everything acts as if it’s going to start, the engine clicks, and that’s all. In the past, I’ve disengaged and reengaged the transmission shifter into Park, or just push it to the left and right, and then she starts right up. I’ve removed, reinstalled and tightened the battery cables – both had clean, solid connections.
I imagine it could be an interlock on any number of things, or a starter/relay problem, but rocking the shift lever a bit SEEMED to make a difference in the past. It won't turn over when in Neutral, either.
I’ve read here about a transmission interlock that prevents the transmission from going into Park. This problem is obviously a bit different. But could it be a mechanical interlock problem? I don’t have my Service Manual on DVD here where I am now, and I can’t start the car to go get it (!).
I haven’t yet tried to jump-start it, but I don’t believe that’s the problem I have. The battery is relatively new and strong, and the cable connections are solid.
Any ideas out there about how to diagnose this, or get to the interlocks?
Thanks in advance!
