Can an anti-theft alarm on a 1997 Ford shut down the fuel pump?

Answer 1

I think the "short" answer is probably yes, BUT... Since I'm not familiar with the alarm system on your vehicle [and the specs of the system will determine feasability], this answer will generic in nature. Therefore, all of the following explanation MUST BE QUALIFIED with, "I think!" IF your alarm system has a terminal(s) for "shutting down" other functions in the vehicle upon activation of the alarm, then the fuel pump relaycould be "disconnected" from its current tie-in point [probably to a terminal [or a "master" relay tied to this terminal] on the ignition switch, which is "hot" only when the ignition switch/key is "ON"]. Due to the amount of current [Amps] that the fuel pump probably draws, you do not want to try to power the fuel pump through the alarm system [that could totally destroy your alarm system electronics]. You want to have the alarm system only control the fuel pump relay which uses much less current than the pump itself. Unless you are very "savvy" with automotive electronics, it would be much safer to have this done by an automotive electronics technician, or at the absolute minimum, a very experienced mechanic. If this job were screwed up by a novice, it could result in fatal damage to your onboard computers, other delecate electronic devices, and in the worst case even cause a fire, possibly destroying your vehicle, or worse causing bodily injury.j3h.
