RE: Help broke down
I found out that if the ECM sees the fuel shutoff solenoid is shorted out, it shuts down the engine. If it sees it as an "open circuit" I.E. - Disconnected, it will still allow the engine to run. Only problem is getting the fuel past it. Hence, taking out the guts for it and putting it back on when it fails, and leaving the wire for it disconnected. You get a check engine light, but not a shutdown light.

Of course, you may end up with a different problem if you have leaky metering actuators. The engine may not shut off right away, but that problem will not keep you on the side of the road. Worse case scenario, you might have to unplug the big square power connector on the left side of the ECM to shut the engine down if you do have worn out, leaky actuators, but at least you aren't a sitting duck at the mercy of a tow truck.
