What makes you think you have a short? The fuel pump relay will click off and on normally since it will be turned on via the ECM for 2 seconds to prime the fuel system as soon as you turn the key "ON", and then again as the oil pressure comes up upon cranking the engine over.

you know i never thought of that now it make sence.well any way thanks 4 the info.you wouldn't happen 2 know how to hook up a alarm

Vipers are neat alarms. They aren't too bad to install, but the power door lock wiring can be confusing without the book. The best thing to have is a wiring diagram for your car.

Here's the installation manual from DEI for your system. They also have the
Owner's Manual if you would like.
