Several times today I've had my car just quit, it has restarted each time but usually only after some fiddling around, first try on restart is usually a no-go.
Got it home and checked codes and got 1-4-4 on the ignition, copy/paste from the 700/900 FAQ: 1-4-4* No load signal from fuel injection system Bad fuel injection relay; faulty wiring from LH to EZK; bad LH module Engine lacks power; stalls; doesn't start or is jerky

No other codes. Just replaced the power stage last week after a similar incident and all was well for several days. After the first incident where it quit going down the interstate and wouldn't re-start (tach wasnt showing anything while cranking) I popped in the spare fuel relay I carry in the car, no change. I swapped in my old RPM sensor that was replaced just because the sheath around the 2 wires was splitting, it still worked fine....still no change. Got a new power stage and life was good again, car ran perfect.

Anyone have experience with code 1-4-4?
Could my spare fuel pump relay thats still in there be causing this?
Could it be time for a new EZK box?
Anyone have a working 937 box for cheap?
