    I had a similar problem begin just this morning. I thought the car was out of gas at first (because my fuel gauge has never worked properly), but after getting gas and putting it in, the car will start - hesitantly - and then sputter out within 10 seconds. I have a feeling the pump is shot, and thats about a $300 fix. I also have a feeling its all my fault because I haven't been keeping the tank full during this fuel 'crisis' and I haven't installed a locking gas cap yet even though I believe I've been siphoned twice (with subsequent running-out-of-gas incidents that could only be explained by theft),,,this probably helped burn the blasted thing out.

    Here's to $5/gallon gas! :-\

    I had the same problem. Fuel pump failure is common on the blazers. Another cause for a "no start" condition is a faulty ignition coil. You can get one at any auto parts store. The rivets need to be drilled out when removing the old coil. The microprocessor and heat-sink are normally OK. Just remove it and fasten it to the new coil.

    Having the same problem. 2000 Blazer 4D 120K miles. Started hesitating initially, when engine was cold. Then hesistation persisted for first few minutes while driving. Then it would start sometimes and not others. Usually could get it started after pumping the pedal. Now won't start most of the time, but randomly does.

    Have replaced fuel pump 2X, fuel pressure regulator, spark is okay, replaced cam-shaft position sensor, fuel pressure is okay, changed cap, rotor, plugs. Dealer is at a loss, they fixed a wire, didn't fix the problem. Any suggestions?

Make sure that your fuel presure is up to at least 60 psi if not that could be your problem. If not, make sure you are getting spark, if not could be your Crank sensor or ingniton module ECM. Usually if your Engine control module wouldn't be bad because of your fuel pump is working, but may not be putting out the proper pressure for the fuel system. Fuel Pumps are a Problem with that year..

I had a very similar issue for a while, except mine would randomly die. After about 10 or 15 times of my vehicle dying in rush hour traffic and refusing to start for roughly 20-45 minutes, i had already replaced a fuel pump, distributer cap and rotor, plugs, plug wires, ignition control module, and various other small tedious items i found that when i used 87 octaine regular unleaded instead of the 89 octaine unleaded with ethonal that my problem simply dissapeared. If you use ethonal, pay the 10 cents more for regular unleaded to save the heart ache and pocket break.

My 2000 chevy blazer has been running slighty rough then yesterday when I went to start it up there was a bang and some smoke came from the engine then it raced a bit then dropped down to a very off rough...

Hi Shane, I would suggest you take the vehicle for a scan or if it doesn't run get someone to come and scan it. I would think that the problem has something to do with the ignition timing which on your vehicle may be a defective camshaft or crank shaft sensor. I'm making a blind guess so I revert to my first suggestion. Regards John

Truck Wont Start and Battery Runs Down.

get a load test done on you battery and alter nator and check your starter for corrision check battery connections before you jump start it and when hooking up cables to your truck let it charge for a few minutes before you crank it if alternator is fried it will only run on juice of battery then will die.the clicking sound is your starter trying to engage but not enough cranking amps left in battery if you can get it going or take the battery out and take to a good auto shop and get them to load test it no point replacing a good battery just to find out it is alternator or starter
I personaaly think it may be alternator but suggest you test if battery is good starter as well ! more thing check that battery terminals are clean and tight

Sounds like the bendix is stuck in the starter. When this happens, the starter energizes and turns, but the gear does not kick out to make contact with the flywheel. Have someone tap on the starter while cranking the engine.
