Help: Car won't turn off, ...unless I pull the coil wire Options

[boxsterfan]

Getting my car back together after replacing the fuel pump with a 2-port Bosch 69133 unit from Napa.

Car starts as normal, but when I turn her off she just keeps running. I can remove the key from ignition and she keeps running. And of course, this isn't some sort of overrun condition....actual running. Pull the coil wire and she dies as expected.

Other notes, fuel pump is wired to switch power up front (previous owner did this).

:dunno:

Electrical problems can be really strange. I once had a problem where the car would keep running as long as the left turn signal was on. I could remove the key, lock the door, and walk away from the car and the motor would keep running.

I eventually figured out that the "parking light" feature was feeding power back into the ignition switch, sending it to the fuel pump and oil and such.

The feedback was because I had swapped in a single-filament bulb for a dual-filament one in the taillight. I had done that a couple of months before noticing the problem, because I don't usually park the car with a turn signal on...

So, does the turn signal switch have anything to do with your symptoms?

Good question Dave. I'll find out more this weekend. I don't believe my turn signal was on and I haven't changed a bulb or done anything with the car in that area.
