Your Rendezvous has GM PasskeyIII

"When trying to start the vehicle if the engine does not
start and the SECURITY message comes on, the
key may have a damaged transponder. Turn the ignition off and try again."

So if the SECURITY is showing on message center then the key is not recognized and you will need to try a different transponder key.

If SECURITY is not showing, then set the emergency brake and move transmission selector to N(uetral), keep foot on brake and try to start.

The loss of fuel pressure does not necessarily mean an external leak. Your systems has a number of pressurised circuits. any check ball can leak and you will lose pressure.

Taking the vehicle to a qualified repair shop that has the diagnostic tool to read the DTC'S - diagnostic trouble code's . Then they can diagnose the problem . None of the thing's you tried will work , not for anti-theft systems , not suppose to. The computer isn't seeing the correct transponder code or the anti-theft module is the problem . Having the vehicle checked by a qualified service tech is the only way to resolve your problem .
Ford's PATs - Passive Anti-Theft System Information. Permalink
Many Ford trucks, vans and suvs use PATs (passive anti-theft) keys. These keys prevent someone from copying your key to a blank and using the blank. There is a small chip in the key which the vehicle must recognize before it will start.
PATS is Ford Motor Company's passive anti theft system. In 1996 it started showing up on select models of Ford and Lincoln Mercury vehicles. The keys for these vehicles have a tiny radio frequency transponder imbedded in the plastic Head.


When you attempt to start the vehicle, the onboard computer sends out a RF signal that is picked up by the transponder in the key. The transponder then returns a unique RF signal to the vehicle's computer, giving it the ok for the vehicle to start and continue to run. This all happens in less than a second, and is completely transparent to the vehicle operator. It is a very effective system that does its job without the vehicle owner having to think about it, or modify his / her usual routine.

You need to have the original key close to the ignition so the transponder will pick it up. The easy answer would be go to your local dealer and have a new key cut with the right transponder to the new lock cylinder.

1 First you will need to purchase a blank Toyota transponder key. You can do this from the dealership, a locksmith, or an online source such as eBay. Once you have the key, take the blank key and the master key to a locksmith that he or she can duplicate the key. This will be much cheaper than the dealership.

2 Now that you have the newly cut key and the master key, you can program the Toyota transponder key. Sit in the driver's side of the Toyota vehicle. Press and release the brake and gas pedal simultaneously.

3 Insert the master transponder key. Do not turn it. Push and release the gas pedal 5 times within at least 15 seconds of inserting the master key.

4 Press and release the brake pedal 6 times within 20 seconds of completing step 3, then remove the master transponder key.

5 Insert the newly cut transponder key into the ignition, but do not turn. Press the gas pedal once.

6 Wait up to 2 minutes or whenever the security light on the dashboard turns off. Once the light goes off, remove the new transponder key and press the brake pedal once. The new transponder key should now be programmed. Test the key by attempting to start the engine. If the engine does not start, repeat the steps above.

To deliver heat into the area you drive from... That and cool air, defrost for the windows so you can see where you are going... That's why.

You will have to take the vehicle to a Mazda agent and ask them to program a transponder key for your car. Every key is specially programmed for a particular vehicle according to its VIN number.

the car came with 2 RKE FOBs
are both dead.?
alway have 3 FOB if not you can not reprogram a new one. self.
can cost you $300 for more to tow your car to the dealer if the 1 fob dies. never run one fob. or bad happens.
put in a new battery in the FOB for door issues
the transponder part does not use the battery .
the transponder must be good, or the car would never run.
the jeep cuts fuel after 2 seconds if the transponder fails.

The symptoms you describe exactly match those I encountered a while ago with an Isuzu engined Vauxhall where the management system falsely detected an overboost condition.

I didn't do the repair but I understand the car was fitted with a new egr valve.
Sometime later a very similar set of symptoms were presented but in that case the crankshaft sensor was cutting out when the engine reached a fairly high temperature. Switching off and waiting a few minutes was all that was needed to restore performance for a while.

Try disconnect battery for 30 minutes. Sounds like new key not synced with computer. Might need reprogram.
