Expert:  Gary replied 3 months ago.

NO
Customer: replied 3 months ago.
I CAN JUMP STARTER WITH KEY ON CAR WILL RUN ABOUT 8 SECONDS THEN STALL FUEL PUMP DOES NOT STAY RUNNING
Expert:  Gary replied 3 months ago.

the odds are this issue is the ignition lock cylinder itself not reading the key

was the ignition lock cylinder replaced as this key should have a small black chip in it

Customer: replied 3 months ago.
LOCK CYLINDER WAS REPLACED AND GOT KEY FROM GM DEALER WITH BLACK CHIP AND RIGHT RESISTANCE
Customer: replied 3 months ago.
ARE YOU STILL HELPING
Expert:  Gary replied 3 months ago.

if the key resistance is correct and it has a new lock cylinder and it still is not allowing it to crank and locking out the fuel and it shutting off when you jump the starter then the only thing left to cause this would be a bad theft module located behind the passenger side of the dash

can you look into newrockies.com

Customer: replied 3 months ago.
CAN A GUY WIRE IN A RESISTOR TO BY PASS KEY TO SEE IF THAN NEW IGNITION LOCK CYLINDER IS NO GOOD
Customer: replied 3 months ago.
I HAVE ONE OF THOSE KITS I TRIED THAT IN APRIL IT DIDNT HELP I PUT OLD MODULE BACK IN BUT I STILL HAVE THE ONE FROM NEWROCKIES
Expert:  Gary replied 3 months ago.

but the cylinder is brand new and all the resistor does is bypass the lock cylinder so if the new rockies did not work then there has to be a bad computer

Customer: replied 3 months ago.
AT THAT TIME THERE WERE SOME FUSES WITH NO POWER THATS WHEN YOU ADVISED TO REPLACE IGNITION SWITCH I REPLACED THAT AND KNOW I HAVE POWER TO THOSE FUSES THE CYLINDER WAS NEW THATS WHAT I REPLACED FIRST
Expert:  Gary replied 3 months ago.

with it still not working after the bypass kit from newrockies the only thing left is the theft module is bad or the computer is bad

Customer: replied 3 months ago.
