Blazer sat for years put a new battery and gas in it i hear the pump but wen i turn it over sounds like its about to start but doesnt.


make sure its getting gas. and replace plugs if need be. have a good one !! also make sure air filter is clean and does not have a nest in it. i have changed a few air cleaners that had this in it. good-luck ! also make sure its sparking good.

Getting alot of air in gas line to carb


Chevrolet Blazer 1998 year model doesn't have a carb, so you must have chosen the wrong section to put your question. Nevermind, i'll assume your truck is an much older version so it has a carb. In that case you get air on the line because you have a puncture in the fuel line . To be sure of that you can do a simple test: take out the fuel line from the pump and block it; take out the fuel line from the tank an pump some air on it, if the pressure drops rapidly then you surely have a leak - just look and listen for it and replace the damaged part.
If you really have a 98 model (with injection, not carb) then the fuel pump inside the tank(or its sump) is defective - replace it completely.

Wont start up...


Check for a bad ground from battery to engine. Then check the module inside of the distributor cap. It should be a black crescent shaped unit about three inches long that all the wires plug into.

No spark when trying to start the engine on 98 chevy blazer


Check for dead battery. Test wipers, radio, headlights and heater fan. If all work normally, battery is probably charged and you may have bad starter or alternator ....

Good luck...
