Sounds like the fuel pump is not staying on or the ingtion switch doesn't make in the run position ( happens alot to vehicals take have lots of keys hang on the switch) The sparp going away is easy to check with a test light theres a connector on the distrubutor that has a heavy red wire plugged in that goes to the B+ terminal it should be hot with the key in the run position. if it's dead fix the connection at the ingtion switch ( it's on top of the steering collum and all but one wire will be hot with the key on, that one comes hot in start) if it's good the fuel pump is next it has a fuse on the passenger side firewall next to the fuel pump relay. Fuse bad or relay bad or dirty it'll act this way. The start wire entergizes the pump in crank position. then the oil pressure switch takes over and keeps the pump on. theres 3 wires on the oil pressure switch the center wire works the light the left one is fuel pump fuse power and the right one is the fuel pump. the oil switch can go bad and the connection can go bad the wire can fall off or get broken. the wire to the fuel pump may not get all the way to the pump.. You can add power to any wire on the swich with out hurting anything. all of the wires will be hot with it plugged in and running. unplugged two wires are hot with the key on ones the light ( oil Pressure light) the other is the key on power for the pump with oil pressure the switch closes and the pump comes on and it'll be powered right off the starter as it's cranking. If the switch is leaking oil its likly failed too.

You need to check the crank sensor, this controls tthe injector pulse. If it will attempt to start with alternate fuel but not on its own, it sounds like the injectors arent pulsing, so your not getting fuel. Try the crank sensor first.

it could be a fuel pump they are quite common on the chevy trucks and SUV's. If it has a "Vortec" engine which it probably does, they run whats called a poppet nozzle fuel injecter that requires i think no less than abaout 53 psi of fuel pressure to run, you would have to put a fuel pressure guage on it to be sure and they are quite expensive

Engine starts then dies, replaced filter,pump,and injection rail. Will run if you dump gas down intake, but dies when fuel runs out.


crawl under the Blazer and hit the gas tank with a heavy rubber mallet with the key in the on posision now try to start the blazer if the blazer starts up replace your fuel pump trust me if you fuel pump is stuck this can free it for and emergancy and you can get it some were

Loss in fuel pressure


Need a new battery first, or charge the battery...if the battery is over 3 years old, I would just replace it, also may need a higher output alternator with more amps, to run the electronic fuel injection, fuel pump, and ignition etc...
