Question about 2001 Chevrolet Blazer
Sterring column replaced,wont start
Mine would not start and I had a Chevy dealership mechanic, look at it and we discovered a tiny pin head burn on my distributor cap. We almost didn't see it. After we changed it, haven't had any problems since. Still have the Blazer today. Hope that helps.

The ECM does not recognize the different key. A tool referred to as a Tech-2 plugs in to the scan port, the truck is put in learn mode and the prompts on the tool are followed, this "programs" the ECM recognize the new key.

The first thing I would check is you are getting both spark and fuel at the cylinders. Remove one spark plug at a time and connect to it's plug wire while holding the end of the plug against a solid ground. Have someone crank the engine. If you see a good spark in the spark plug gap I would then make sure you have fuel at the cylinders. Cranking the engine for a bit. Then pull each spark plug out and check that fuel is on the end of the plug. If you have both fuel and spark at the cylinders I would look more at such things as timing belts, sensors, etc.

Try to do the crank relearn:
Ensure that your battery is fully charged before attempting the relearn procedure. Do not leave any battery charger or jumper cables attached to the battery. Close the hood completely. Some applications require that the doors remain closed during the procedure.
1. Rotate the key to the start position to attempt to start the vehicle (the vehicle will not start).
Allow the key to return to the all position (same as if the vehicle would have started). The theft system light will flash (or stay lit) on the dash for approximately 10 minutes.
2. When the theft system telltale stops flashing (or turns oft) turn the key to the off position for 5 seconds and then attempt tostart the vehicle. The vehicle should start on this cycle.
3. Once the vehicle is running, the password relearn is complete.
00 + S10

3. When the theft system telltale stops flashing (or turns off) turn the key to the off position for 5 seconds and then attempt to start the vehicle.
4. Repeat steps 1 through 3 two more times for a total of 3 cycles/30 minutes.
5. On the next cycle of turning the ignition key from off to crank the vehicle should start
6. Once the vehicle is running, the password is learned and this completes the cycle.
7. Clear any DTC's with a scan tool if necessary. DTC history will be cleared after 100 ignition cycles.

The best thing to do is to buy a Chilton,s repair manual. It has step by step procedures. You can get one at most auto parts stores. They coast anywhere from $10-$30 dollars.

I would check to be on the safe side the fuel filter is going in the right direction. The arrow is pointing towards the engine away from the fuel tank, Then you need to make sure the fuel pump wiring connections are good contact and did not come loose when driving.

Before spending several hundres on a fuel pump, I recommend doing a fuel pressure test. You can get a test gauge pretty cheap at a parts store. If the pump is junk, you raise the truck, lower the fuel tank, unplug the electronics from the pump at the top of the tank, then with a hammer and flat head scrwedrive, gently tap the lock ring in a counter clockwise direction until it pops off. Pull the pump assembly out and install the new one. Reverse directions to install.
