    The engine starts like it is going to run but quits right away. Sometimes it starts and runs fine. I have taken a few short trips with it with no problem. But when it does it, the engine fires then just quits.

Check the fuel delivery, first. It could be fuel pump or an obstruction. The best way is to start the car in park, then run over to the engine compartment and rev up the throttle. Keep idle higher than normal. If it wants to die, rev throttle higher to compensate. If it makes no difference, verify fuel pressure when engine dies. Usually ignition related wont even allow the car to start. Any service engine indication?

If this engine is a VORTEC then you may have a problem with the internal fuel system. Under the top plenum there is a fuel reg and poppet valves that inject fuel into the cylinders. Sometimes the tubes that run fuel from the reg to the valves can leak and cause your problem. This cannot be found with pressure check because this occurrs after the reg. PS fuel mileage will go down. Let me know if this helps.Moe

99 blazer security light stays on


The security light means the computer is not reading the chip in the key.
You should have a sensor in the key lock and a chip on the key programmed for the security system.
I would try a spare key first. If you don't have one, you can get one from the dealer or some locksmiths.
If you know you have a good key, the problem may be with the sensor in the lock cylinder.

2000 chevy blazer starting issues


swng,
1) Is the service engine soon light ever on when engine is running?
2) Per your description I would look at the ECT sending unit. It sends coolant temperature information the the Engine Control Module for proper fuel delivery for cold engine start. It may have lost its calibration.
Let me know.
