ECM information needed- anti theft switch

[tckrapp]

I remember reading a members comment about interupting the signal from the ECM to the injector relay as a means to have a hidden switch to prevent a potential thief from starting the truck. It seems that this might be a way to pump oil to the engine prior to starting, especially when the truck has been sitting for an extended period of time,

I would appreciate any thoughts on this and if anyone has done this including results and instructions. Tom Krapp

I think they were talking about pin 33 on the ECM. The Fuel Shut-Off circuit to the VP. With this switched off, I dont know if it would still crank, to do what you are talking about.



chances are it would though.
