Chevrolet Repair: Chevy Venture wont start, daytime running lights, chevy venture

Question
QUESTION: My 2002 chevy Venture wont start the car turns over but wont start. However if i disconnect the battery for one hr and reconnect the car starts and runs fine but whenever I CUT IT OFF IT WILL NOT RESTART!! What causes this, is there some type of anti theft activated.  Theres a red light flashing on my radio??

ANSWER: HI RAY,YOU ARE CORRECT. IT IS CALLED THE PASSIVE LOCK SYSTEM. USUALLY HOWEVER BY DISCONNECTING THE BATTERY AND RECONNECTING IT WILL NOT WORK..FOR A TEMPORARY FIX YOU ARE SUPPOSE TO TURN THE KEY ON FOR 20 MINUTES OR INTILL THE RED FLASHING LIGHT STOPS AND THEN YOU CAN START THE ENG. I NEVER SAW ONE DO THIS BEFORE.[LIKE YOURS].PROBABLY A FAULT IN THE BCM[BODY CONTROL MODULE.] ANYWAY WITH THAT SAID THE IGNITION LOCK OR PASSIVE MODULE IS FAULTY. YOU WILL NEED TO GET THIS SCANNED AT A GM DEALER OR IF YOUR MECAHNIC HAS A GM TECH II SCAN TOOL HE OR SHE CAN DO THIS WORK. PLAY IT SAFE,GET A NEW KEY WITH LOCK CYLINDER AND READER. BE DONE WITH IT.. OH BY THE WAY, THE KEY ON 2O MIN PROGRAM [ABOVE] IS ONLY GOOD FOR 25 TO 30 START UP'S. THEN AFTER THAT YOU WILL NOT BEABLE TO GET IT RUNNING PEROID!!!! IF YOU NEED MORE HELP DROP ME ANOTHER LINE. PLEASE WHEN YOU LEAVE THIS SITE WOULD YOU MIND RATTING MY ANSWER..THANK YOU, TOM..

QUESTION: the headlights come on when you turn the key on this will run the battery down before the relearn in complete.  can you replace the lock with a non-passive key system

Answer
HI RAY,YOU COULD REMOVE THE HEADLIGHT RELAY OR FUSE FOR THE DAYTIME RUNNING LIGHTS IF YOU ARE WORRIED ABOUT KILLING THE BATTERY DURING THIS SET UP TIME..TO ANSWER YOUR OTHER QUESTION YES YOU CAN BY INSTALLING A DOIDE IN BETWEEN THE IGNITION CYLINDER AND PASSIVE LOCK SENSOR. THIS KEY NEEDS TO READ THE DIODE BEFORE IT WILL LET IT START. THE PROBLEM IS YOU HAVE TO KNOW THE RESISTANCE OF THIS DIODE THAT THE SENSOR IS LOOKING FOR..WE HAVE DONE THIS AT OUR SHOP BUT IT IS TIME CONSUMING. RADIO SHACK HAS DIODES THAT YOU WOULD NEED. INSTALLING A NONE PASSIVE LOCK CYLINDER WILL NOT WORK,BECAUSE THE BCM IS LOOKNG FOR THIS SIGNAL TO START THE FUEL PUMP RELAY, INJECTOR PULSE AND CRANK SIGNAL AND ON AND ON.IF YOU HAVE A GOOD ELECTRICAL TECH IN YOUR AREA HE OR SHE CAN MORE THEN LIKELY DO THIS. HOWEVER AFTER IT IS ALL SAID AND DONE IT MAYBE CHEAPER TO INSTALL THE NEW LOCK CYLINDER...THIS IS A COMPLEX SYSTEM,MADE THAT WAY SO NO CRIMINAL CAN RIP YOUR CAR OFF. THANK ALL THE BAD PEOPLE IN THE WORLD FOR THIS,I DO EVERY DAY. THESE THINGS ARE REALLY A PAIN IN THE BUTT. HOPE THIS HELPS YOU TOM...THANKS FOR THE RATING
