Question about 2000 Chevrolet Blazer
You may have a fuel pressure problem or the secuirty system has locked you out for some reason due to a false signal or failed part. Do you have any electronic engine control codes? Is the Security light on in the instrument cluster and fishing when you try to start the truck? To check the fuel issue get a can of spray starting fluid from the auto parts store or any hardware store and spray it into the air intake of the engine while someone cranks the engine, if it starts you may have a defective fuel pump, the pump is located inside the fuel tank, the fuel tank must be removed to access and replace the pump.

Whenever I had this problem, it was always cured with a new set of GOOD spark plug wires. Not generic set off the parts store shelf. Get some moisture removal spray and put it on both ends, the coil and the plug, before putting the wires on. Do one wire at a time so you do not get them mixed up. I do not think you have a distributor or a cap. If you do replace it also as it is over 20 years old.

You may have vapour lock in your heater lines. Start engine, put heat lever on high, disconnect one of the lines on your heater core, the one on the flow out side, & see if you have any air coming out. Once antifreese comes out stick line back on & retighten clamp. Make sure your cooling system is topped off. Also your water pump may not be functionihg to it's maximum. Take rad cap off cold & view flow rate. If inadequate you may have to replace the water pump. Good luck!

Try giving it a shot of starting fluid. You don't say if it's actually firing. If it tries or runs for a few seconds off of the starting fluid then try changing the fuel pump relay. It's inside of the glove box on the left hand side behind the little door. If that doesn't work it's most likely the fuel pump.

Check the dash once you turn the key to the run position the passlock runs a security check using a set resistance value through the chip in the key. If the security light begins to flash the reading it received was incorrect or it didn't get a reading at all. You can try reseting the value it is looking for by turning the key to start then releasing it. After 10 minutes turn it off then cycle it start again leaving it in on for 10 minutes then back to off then one more time. After the third cycle has completed for a total of 30 minutes. You should be able to turn the key on and start the vehicle. If the light continues to flash their is a problem with the chip in the key or the connections within the ignition its self. Both are common but a Pass Lock Relearn as described above will usually adapt to the poor connection values. Hope this helps.
