2001 Chevy S-10 Blazer Will not start immediatly. Will turn over, then wait a couple of seconds, then it will start. If vehicle sits for over 24 hours it gets very difficult to start. You might have to turn it over 4-5 times before it finally starts. Once it starts it runs and idles okay.

check the fuel pressure regulator and see if it has a leak (common problem)

SOURCE: My chevy blazer doesn't start , i have ignition

after the 15 sec. the gas smell means it could be flooding. when you say you have ignition you mean spark? your fuel pump can still come on and you can hear it, but that doesnt mean its not bad.

CHECK FOR A LEAKING INTAKE MANIFOLD GASKET, USE A CAN OF CARB SPRAY AND SPRAY AROUND THE TOP OF THE ENGINE, IF U HIT ON A LEAK U WILL HEAR THE ENG CHANGE TONE AND IDLE RPM.

Check the fuel pressure, bad fuel pump or sock on the fuel pump and fuel filter check spark plugs and check distributor cap, a fuel pump is $273.00 or a bad injector $110.99 or BWD Fuel Vapor Pressure Sensor for $35.99 any of these parts could cause the problem, so without doing a fuel pressure test it is a guess, if the vapor switch is bad it could cause a long crank time if the fuel pump is bad it has a check valve in the fuel pump, if the check valve goes bad the pump can't maintain fuel pressure so on start up the fuel has to pump from the tank all the way up to the fuel rail, if the injectors is bad it could leak after engine shut down and cause you to lose fuel rail pressure. Also the fuel vapor sensor could be stuck open and could cause the problem, all need to be tested, you can rent the fuel pressure tester from AutoZone or advance auto or Shucks they return your money when you bring the tool back as long as you buy the parts to repair it from them. That would be the first thing I would check fuel pump pressure and if you replace the pump then change the fuel sock as well. That model was not meant to burn ethanol and can kill the fuel sock the fuel pump and filter.

SOURCE: '95 Chevy Blazer driver's sit wire doen't have

the wires between the door and frame are probobly broken from opening and closing so much....run into it a lot...cheap fix is to cut the rubber boot off with a razor knife and splice in a piece of wire....tight working in there and make sure you seal them up with heat shrink and lots of electrical tape,,,good luck...Lee
