Do you have wiring diagram?

Is your vehicle not starting and you want it tested, what exaclty do you need to test it for

Normally with switches I bypass the switch with a fused jumper wire and then activate the circuit and see what happens

yes i have a diagram , not for the switch persay, but the ignition in general

right now it doesnt start with the key, i have a toggle switch in its place, as long as the ignition is turned on, the car will start, but then i t dies instantly, which is a whole nother problem in itself
it has the 2.4 in it

Sounds like a Passlock issue to me. If you're trying to start the car with a switch... you still need the key in the ignition switch to send the R-code from the ignition lock to the cluster (on 95-99) or BCM (00-05)... then send the fuel password to the PCM to let the car run. If you're bypassing it to use a push button or whatever... get a DEI 555L bypass module and connect it to your alarm.
