1. Insert key in ignition and leave in the OFF position
2. Locate the Data Link Port. It is located under dash drivers side. Be sure you know which pins are 8 and 4. (Note port is wider at top) Your OBDII port will not
have numbers.



3. Make sure there are metal contact pins in terminals 8 and 4. Connect 8 to 4 with a
suitable jumper wire (leave the jumper wire connected throughout the programming
procedure). Make sure you know which terminals are 8 and 4. The vehicle will respond
by locking and unlocking the doors to signify entering of programming mode.

4. Close doors.

5. Turn ignition to the ON position (as far as you can go without cranking the engine).
Doors will lock.
6. Press and hold both the LOCK and UNLOCK buttons together on the first transmitter to
beprogrammed. After about 15 seconds, the vehicle will respond by locking and
unlocking the doors. Release the buttons on the transmitter.7. Within one minute, repeat the previous step on the remaining transmitters to be
programmed.

8. Remove jumper wire applied to the OBDII Port.

Hard to say - using the data port to program a remote is unusual, and depending on what device or procedure you used, you may have screwed up the datalinks. You should start by using a code reader to see what trouble codes exist.

voltage is a bit low. have you tried rotating the engine by hand with a socket on the crank., just to see if the engine is free to move. if the starter engages but not turn, it could be the voltage as they can be regulated this would stop it from flattening the battery via the solenoid, its usually around the 11 volts mark on some types. as low volts will damage the battery. or the battery amperage is not good.

Hey Baptized,
You need to replace ALL the gaskets that seal coolant from ANYTHING... You may have a cracked head, cracked intake manifold,, or at worse a cracked block - between the coolant passages and the combustion chamber area...If you have a aluminum intake and cast iron heads.. this is a potential leak creator when the engine gets hot and cold quickly...make sure ALL the gasket surfaces are CLEAN.. and use:

Could be other bad pulleys. Look at the belt inline with the pulleys. If one is bad, you will see it misaligned. With the belt off the pulleys should have very little to no play and should turn by hand smoothly.
