1999 Chevy S-10, how can I bypass the Security Fuel shut off sytem?

This problem happens over and over. The truck will turn over but not start due to the Security System. Have spent a lot of money just to be told it is only the security system. How can I disable or bypass the system?

    well cant get my truck to start ...Security light come's on  and wont let me start../

    The truck will start but then die immediately, I found that if I jump the fuel pump relay contacts the truck will continue to run. What I haven't been able to find out is what is supposed to hold the relay on. A wiring diagram is the only way to solve this problem, which seems to be pretty wide spread judging by this web site. If and when I find a diagram I will let you know where I found it.

The way that i was told how to do a quick fix for is to hold the key in the electrical start and the actual start up of the engine and hold it there tell the security light is solid and then turn off the truck then bring it back to that point and let it blink until it turns off then you can start the truck.

You need to do a key relearn procedure as follows:

  1. Turn ON the ignition, with the engine OFF.
  2. Observe the Security telltale, after approximately 10 minutes the telltale will turn off.
  3. Turn OFF the ignition, and wait 5 seconds.
  4. Repeat steps 1-3 two more times for a total of 3 cycles or 30 minutes. Important: The vehicle theft deterrent system learns the key transponder information on the ignition switch transition from OFF to CRANK. You must turn the ignition OFF before attempting to start the vehicle.
  5. Start the vehicle. The vehicle has now learned the key transponder information and the PCM has now learned the fuel continue password.

Your security system is a very complex piece of kit and it links in to several circuits in the truck /doors /hood ignition etc and without the correct wiring diagrams it is almost impossible to bypass
a main dealer or auto electrician with diagnostic facility is sadly your only way around this problem
i know from experiance after nearly 2 days and a box load of connectors and wire !! chris

I have a 1999 Pontiac Grand Am why won't my car start? it just spins but wont crank. I changed the core packs and it's still not cranking


The term " CRANK" is what the Starter is doing to the Engine. I think you mean is 'it Cranks but wont Start'.
Is the engine getting Spark? Is the engine getting fuel? You need to check these two things before randomly swapping out parts.
If it's fuel starvation.. Check the fuel pump relay or possibly a bad Fuel Pump.

2008 Chevy Avalanche. Cranks, but why won't it start?


There is no magic fix button provided as standard equipment on your vehicle. You will need to perform standard diagnostic procedures to ascertain the source of the failure to start.
Begin by doing a readout of all stored codes from the ECU. This will give you a starting point from which to proceed in diagnosis. Check all systems, including FUEL, IGNITION, and SECURITY.

How to bypass passlock on 1999 chevy blazer


The most common repair is to replace the ignition lock cylinder due to broken wires inside the steering column. Most common problems related to the Passlock family involve the Passlock sensor. The sensor is part of the ignition lock cylinder on Passlock I and Passlock II systems. ( Where the key goes ), Good-Day!

ENGINE STARTS FOR 10 SECONDS AFTER TURNING IGNITION ON AND OFF FOR A NUMDER OF TIMES,AND THEN STALLS .WON'T START AGAIN UNTILL IGNITION IS TURN ON AND OFF FOR THE SAME NUMBER OF TIMES.


CHECK FUEL PRESSURE SHOULD BE 58 - 64 PSI. IF YOU HAVE ZERO FUEL PRESSURE OR LOW FUEL PRESSURE.AND FUEL FILTER BEEN CHANGED YOU HAVE FUEL PUMP PROBLEMS.TO BE ON THE SAFE SIDE REPLACE FUEL PUMP RELAY TO MAKE SURE ITS NOT BAD.IT WILL SHUT OFF FUEL PUMP IF FAULTY.

SECURITY LIGHT COMES ON WHEN DRIVING,EVERYTHING IS OK BUT AFTER MAYBE 4 OR 5 TIMES OF SWITCHING OFF THE ENGINE, NEXT TIME TO TURN KEY TO START ENGINE TURNS BUT FUEL IS SHUT OF. PASS LOCK OPERATES. WE THEN...


The most common reason for this condition is a faulty ignition switch. It loses contact momentarily while cranking, causing a voltage loss to the security system and starts the 10 minute security timer in the computer. It will not start until the timer runs out. Usually the key has to be left on after a start attempt for the ten minutes. Some cars require 30 minutes. I hope this helps you and please rate this,

1999 chevy malibu won't start


if your theft light is on you must disable the security system you have to use your remote to unlock the vechicle which will turn off the security system if your remote is not working you can unlock the rear hatch with the key and it will shut off the alarm if these things do not work you must have the security system read by a dealer to determin if the bcm is the cause the only other way to bypass it is to replace bith the bcm and the pcm with modules out of a vechicle without theft

CAR WON'T STAY RUNNING


when key on and engine off, does the security light flash constantly? if so its shutting down the fuel pump, it starts momentarily due to the computer priming the engine with fuel. how to reset, turn key to run position, leave it on touch nothing, takes 10-12 minutes, start watching light around 10 minutes. it will stop flashing... turn key off, then back on and start this will reset the security system. they are sensitive on this platform car it will happen again. good luck!

There is a definitive solution that I'm pretty sure can work for your case too. When people tries bypassing these security systems, they always do it with a simple resistor. Wrong! That doesn't work anymore. Look at this site, it was the only way I was able to save my beloved 94 Park Avenue: http://newrockies.com/vatsbypass My car had a Passkey system, but the difference between PassLock (yours) and PassKey is that the former has a resistor in the lock, while the latest has it in the key. For the rest, they are the exact same system.
