Hello and welcome. My name is ***** ***** you for visiting the site, I am reviewing your question and will reply shortly, thanks.
The PASS-Key II (R) module produces the Theft Deterrent Fuel Enable signal when ignition is ON and the proper key resistor pellet is sensed by the PASS-Key II (R) module. The PCM monitors the Fuel Enable signal during crank. If the proper signal is present on the Theft Deterrent Fuel Enable circuit, the PCM enables fuel delivery to allow the engine to start. If the PCM detects that the fuel enable signal is not present or is incorrect while an attempt is made to start the engine, DTC P1629 will be set. The engine will not start as long as this condition is present. If the problem also affects inputs to the PASS-Key II (R) module, the starter motor may be disabled.
There is a test for "Engine Does Not Crank Or Start But SECURITY Indicator Operates Normally" as well.
If the proper signal is present on the Theft Deterrent Fuel Enable circuit, the PCM enables fuel delivery to allow the engine to start. If not they will normally start for one or two seconds and then die.
Normally if the problem is in the ignition cylinder, (or key) it can be easily bypassed, yes.
Where did you go?
I see, thanks. Is there a reason that you don't see that as a Passkey 2 issue?
Yes, opinions don't really mean much without the proper testing. There are many areas of the security system that could be at fault.
