If the SKREES was the culprit, the engine wouldnt crank.If I read correctly, after a few seconds, the ASD relay cuts power. Sounds like something I have read the SKIM security system does if it doesn't recognize the key. We have SKIM on our 2002 T&C. People say if the SKIM fails, best bet is to get a non-SKIM PCM from the junkyard. There is a red Security lamp in the upper dash display. Do you know if the donor had SKIM?
SENTRY KEY REMOTE ENTRY SYSTEM
The Sentry Key Remote Entry System (SKREES) is available as a factory-installed option on this vehicle. It is designed to provide passive protection against unauthorized vehicle use by disabling the engine, after two (2) seconds of running, whenever an invalid key is used to start the vehicle. The SKIS is active whenever the ignition is on and does not require any customer intervention. The primary components of the system are the Sentry Key Remote Entry Module (SKREEM), Sentry Key (integrated key with tranponder and RKE on a circuit board), indicator light, Body Control Module (BCM), and the Powertrain Control Module (PCM). The SKREEM is mounted to the steering column with the molded, integral antenna mounted on the ignition housing. The indicator light, is located in the Mechanical Instrument Cluster (MIC).
OPERATION VEHICLE THEFT SECURITY SYSTEM
Upon failure of proper Sentry Key Remote Entry Module (SKREEM) communication to the PCM, the PCM will shut off fuel after two seconds of run time. The engine will not re-crank on the key cycle that the failure occurred, a full key down sequence must be performed for the engine to crank again. After six consecutive fuel shut-offs, the engine will no longer crank on subsequent key cycles. The failure must be corrected and a valid communication process between the SKREEM and the PCM must occur for the engine to crank and start again
