One year ago i replaced the battery and a terminal post. Now i cant get it started we tried a battery charge and a jump start and it turns over but it wont start. Seem like the battery is not holding a charge. Any ideas ?

I would say get the battery bench tested at autozone. If it turns out good it's not that. I would then look to see if the ground is good for the battery, but I don't think it's a battery issue since you said it cranks. It sounds more like a fuel issue. Can you hear the fuel pump build pressure? Get the fuel pressure tested. The last but less likely issue the key chip is not telling the computer to send fuel. Good luck keep up posted.

I'm not being a wise a$$ in replying to you.
If you're going to buy a small car, buy a Toyota.
The toyota corolla is a 300,000 mile car. Treat it like crap? It'll go 250,000 miles. Give it what it needs? It's guaranteed for 300,000 miles.
A Small truck or SUV? Buy a Toyota.
Full size truck or SUV? Buy a Ford F250 or bigger.
If your next purchase is a Chevrolet, Then you deserve to be in the same place having the same problems. Just hope that it doesn't take place in a really bad spot like it did me.
I've been a life long Chevrolet owner.
My next vehicle purchase will be one of these Toyota's or Fords.
Go to Craigslist and do a search for Toyota Corolla. You'll find multiple vehicles that have over 200,000 miles ORIGINAL MOTOR!
Study the Chevrolet. You'll find that the vehicle was designed to fail. Look at repairing it? You'll find that Chevrolet designed it so that you couldn't do the work on it. They designed it to be fixed by the dealer with the expensive tools.
One tip off: Why would ANYBODY post and rivet into place, an electronic piece of the system ONTO THE TOP OF THE MOTOR ITSELF?????
Electronics don't do well when exposed to heat!!! But, The bright minds at GM/Chevrolet thought that it would be a fun thing to do! Just to get you back into their circle of Union Employee's who don't know how to build a good machine.
One part that describes what I am telling you: Ignition Module. Posted onto a METAL bracket and ON TOP of the motor and what else? It's riveted there!!!
I'll never buy a GM/ Chevrolet ever again in my life!
Sell yours to some schmuck and go out an buy a good running vehicle. One that'll be reliable and safe for you and your family.
Apparently, That's not something that it high on GM's list.

I have a 99 blazer and I was on my way to work when it just shut off for 2 months now it hasn't turned over.I have a new fuel pump ,fuel filter,all o2 sensors replaced, crankshaft sensor replaced,camshaft sensor replaced,new spark plugs, wires, distributer cap, rotor button. I've checked the catalyc converter done a fuel pressure test. What else could it be? Its not getting good spark. What is stopping it from starting??????
#439 of 496 98 Blazer will not idle

1998 Blazer starts normally with no problem but will not idle intermittently. I have already replaced and or tested:
Cam Position Sensor
Crank Position Sensor (it was very dirty but had not been making contact with anything)
EGR Valve (I was just going to clean it but it was beyond that)
Throttle Position Sensor (I know, it was a long shot but I was at the auto parts store and thought what the heck, let's go ahead and replace this too.)
Fuel Pressure is 60 PSI and holds for quite a while after turning off the engine so I am reasonably certain that it's not the fuel pump or a leak in the fuel system.
I have not been able to find a vacuum leak anywhere and all the vacuum hoses appear to be in good shape.
I am wondering if the actual ECM is bad/going bad. When I hook my OBD checker up to the connection in the truck it does not see the truck. I tested it on two of my other vehicles and the checker is good.

Well, I spent over $1000 on parts and labor at 3 different mechanics. Come to find out, my husband fixed it, but the new part he put on was bad!!!!! After changing the IAC, TPS, Ignition Coil, spark plugs and wires, Cam Position Sensor, Rotor button, Distributor Cap, Throttle body cleaned, Thermostat changed and towed because it would just stop when I let off the gas, the last mechanic found out that it was the Idle Air Control. It seems the second thing my husband changed would have fixed it, but the part was bad!!! Be careful with parts!!! I really did need some of the other stuff replaced, but did not enjoy paying for it all at once! It seems Blazers DO NOT LIKE any parts that are not AC Delco!!! Also, it seems my ignition coil (bought at Auto Zone) is not AC Delco and does not fit exactly right, so, we had to re-rout the connection so it would stay snug in the coil!

I will not buy another GM either. I have a 91 Ford Ranger that is still going strong. Easy to work on. My 87 Bronco II was running (fuel pump finally gone out after having it over 16 years). My husband's '97 F150 still going strong, even with a part that needs to be fixed, still drivable, and much easier to work on than GM! Also, can't get aftermarket parts to work on the Blazer, never a problem with my Fords.

Be careful of AC Delco parts too. After the bankruptcy, GM spun off the AC Delco Parts Division and now those parts are made by the lowest bidder. You can still buy AC Delco parts made by GM but the suppl;y is running out. I will never buy AC delco spark plugs anymore because they are made off-shore and you can see the poor quality cvompared to the GM versions. I now use Denso (Japan) platinum spark plugs which I will not have to change for 80,000 miles. However, I will change them at 10,000 miles just to monitor how well my Chevy 4.3L V6 engine is running. Denso TT Platinum spark plugs are cheaper than AC Delco Rapid Fire platinum spark plugs but the quality is obviously ten times better. For example, NGK (Japan) makes the expensive AC Delco Iridium spark plugs that are used in the 2011 ZR6, 550 HP Corvettes.

That's the one part that I had discounted because it didn't seem to make a difference when the AC engaged. I'll try that next,
