I'm in here because the server hosting www.blazerforum.com crashed. This was my one-stop-shop for all my Blazer questions. I can comfortably say it has been turning me into a Blazer expert. LOL
The second thing I want to say is that you should purchase a service manual (e.g. Haynes, Chiltons) specific to your vehicle. They cost ~$15 and are a worthwhile investment. They answer a lot of these questions. For those questions I still can't find the answers to, I post on the Web. Haynes actually includes a list of the trouble codes with the answer next to it. You're lucky, because I happen to have my Haynes manual right in front of me.
Now, to answer your question: There is no PO410 code. There is also no such thing as an air injection system. There is a FUEL injection system, and there is an AIR INTAKE that funnels air into the engine to promote combustion. I suspect what you really meant was:
PO401: Exhaust Gas Recirculation (EGR) system flow insufficient.
This most likely means you need to replace the EGR valve. It's an emissions device. It appears to be an easy repair, and a service manual will tell you how to do it. Hope this helps.

I am trying to drop my gas tank to replace the fuel pump. 1st i am having problems draining tank by siphon from gas fill tube. There is a stopper of some sort blocking my hose. Next I am wondering how to get to gas lines to disconnect. I assume thay are on the top of the tank. Do I drop tank and then disconnect?
The answer is yes. I ran into the same problem three days ago. This really sucked, since I had just filled the tank the same day my pump failed. LOL
But don't worry. Just be sure that when you disconnect the tank, you lower it slowly, using a block of wood and a jack. This prevents the extra-heavy tank from falling and spilling gas all over the place. You can then support the tank on cinder blocks and pour the gas out into another container after it's off the truck. That's what we did. Another option is to siphon it after removing the fuel filler hose, but IMO the first method is faster and easier.
Oh yeah...regarding the second question. We had to cut the fuel filler and recirc hoses. It was the only way. A sharp razor will get it off in seconds. IMPORTANT: They must be replaced by FUEL hoses of the same rating, NOT any other type of hose. This is because fuel eats through rubber, unless it is made out of a special material. We went to four different parts stores, and nobody had the right one. We had to go to the dealer and spend more money, but it's worth it!

Ok this is a multiple question question. What would make the lights in my 2001 Blazer go out? Talking about the lights for the radio, the control buttons, etc. Pretty much the lights for the center dash console. Not all of them mind you. They seem to be going out a little at a time. Part two is can they be replaced??? I would love any help . . . . .
Your most likely culprit is the ignition switch, as it controls multiple things on the dash. This is a common problem on these trucks. If you have a service manual, you can likely do it yourself. If not, your best bet is to take it to a GM dealer. You'll pay a little more money, but it will probably be done right.

Just wanted to inform you all on a bit of news I just learned of this week. At first I read and heard that Chevy was in no way getting rid of the Blazer/Trailblazer name plate in favor of a cross-over like the Acadia/Outlook/Enclave. Because they said tht Chevy would loose its ass, on the deal. Namly because the Blazer family is a very big part of their reveneue.
Well, sadly, they just reversed that decision. This is the last year for this grand family. GM decided it needed 4 of these POS cross overs. I for one think that Chevy
needs to strike out and leave GM. ell chevy could and would prospire. Because they are the one company that has kept GM alive for years. Sorry, Ill get off my soapbox now!!!
We as Chevy Blazer owners need to do what ever possible, to keep ours running and let GM keep seeing them. So, the best name plate to Chevy wont be forgotten!!!!

A good safety item is to drive a piece of rebar into the ground near the vehicle. Take a set of jumper cables and clamp one pos and one neg to the rebar. Then connect the other pos to the frame of the vehicle, and the other neg to the gas tank. Disconnect the battery, and you will have eliminated the possibility of a static charge building up. You don't want any sparkies when you are pulling a fuel tank. It's the fumes that will blow if there is a spark in the area.
Also, if using a drop light, be sure to keep it away from the tank. A Ford mechanic in my home town had done everything right before pulling a Lincoln fuel tank, only to have his drop light fall against the tank, break the bulb, and ignite. He was in his 30's.

We changed the fuel pump several times on one of our Jimmys, thinking they were going bad. Turned out the problem was a bad connection in the plug on the pump, which sits on top of the tank. You can usually reach the plug if you drop the spare tire. It is worth checking to see if your problem is there....

It takes me forever to get back into 2 Wheel Drive after being in 4 Wheel Drive. I keep pushing the 2WD button and restarting the vehicle, and finally it goes back into 2WD. What is causing the problem and is this an expensive repair? Help

We have also had on- going trouble with the 2/4 wheel drive unit of our 2000 Blazer. It would get stuck in one or the other and you could not change it. The problem was diagnosed as corroded wires and connections in the control module located behind the passenger side kick panel inside the truck. This happened in about 2003 (after warranty had expired) and that unit was replaced.To the tune of about $500.00. The dealer suspected that water leaking into this area had caused the damage. They recommended a leak test which was performed but were not able to find where the water was getting in.They said it would probably happen again. It did, about three years later. This time we had our local mechanic look at it and he was able to clean up the wires and connection and apply dielectric grease to it. It is a temporary repair but effective.. That control box will also emit a re-occurring clicking sound for no reason ( turn signal sound )

I talked to a friend and they told me to drain1/2 to 1 quart of oil out of the engine then put tranny fluid in. Let the blazer run-idle for 20-30 minutes. Drain it , addd 30 weight oil and "Lucas" oil treatment and that should quiet the noise. Should I try this before going inot the shop for flywheel replacement???

Well, that is a way to flush a lifter, but I am assuming the flywheel is another issue?
