If you have checked the fuse for the injectors and when you turn the key it sounds like it wants to start then you could try running fuel injector cleaner through the system but better yet determine which injectors are plugged and replace them. Best yet, replace all the injectors it is best for both the vehicle and the environment (emissions) to have them at the same age. With it not starting you can be pretty sure injector number one needs replacing. By injector number one I mean the injector that supplies the first cylinder with fuel to fire. To determine which is injector number one you need the firing order for your vehicle.

SOURCE: my s10 will turn over, but wont squirt gas through injecter

Does it crank? Do you have any codes? Check engine light? Do you have spark? No spark check coil, and connections, also it would be nice to know what year it is. Get codes read. No crank check battery and starter. No codes or lights check crank position sensor, make sure your pcm is good after replacing your ignition mod you could have blown it if you did do it right. (engine computer) Check cam sensor if applies. Crank and cam could prevent it from starting and I know one I think cam controls pcm's fuel delivery on gm's

SOURCE: low fuel rail pressure

who did a conversion on this truck???? the duramax is a common rail engine and can not handle wvo or sve. it will destroy your entire fuel system in no time on this truck. if you want to do a vo conversion you need to get a diesel with an inline injection pump or one of the older powerstrokes. i would suggest you quit trying to run wvo through this truck if you do not want to do a lot of very expensive damage

SOURCE: i have a 1993 s10 blazer 4.3l 6cyl cpi. this truck

I had the same problem in my 91' s10 blazer. Drain the tank, then put about 5 gallons of premium gas. After that put fuel system cleaner and sea foam in the tank. Let it sit their for about an hour. try to crank up the car (you might have to put gas right on the carb until the gas in the tank gets to the engine). If that dose not work you might want to take it to a shop and have them clean the fuel system by hand. It might also be the fuel sensor. I hope this helped also up date us on other problems and if any of our suggestions have helped.

SOURCE: 99 blazer, cranks but no start, pour gas in intake and it starts

Deffinately sounds like a blocked jet in the carb to me.

Find a garage that can reset carbs properly.
If there is fuel in the carb reservoir - your pump is ok. If not - check resistance of fuel pump. Take off fuel supply pipe to carb - and put end in a bottle - turn ignition on for 5 seconds - and check there is fuel in the bottle. No fuel being pumped indicates fuel pump problems. - Electrical or mechanical.

4.3 V6 in 1993 S10 blazer I'm getting fuel to fuel rail but not to injectors. I've replaced the fuel spider but still won't start unless u squirt gas into throttle body


As the injectors are connected to the fuel rail but you are not getting fuel out of the injectors then the problem be with the electronic control of the injectors (immobiliser-cam/crank position sensors-ECM-wiring). Unless you got bad fuel or used a cleaner that has blocked up the tips of the injectors.

If the 2002 Chevy s10 truck has a full tank of gas but wont start and act like it its out of gas what does that mean


have you checked to see if there is fuel preasure at the fuel rail? this can be checked by finding the fuel pressure test fitting somewhere on the fuel rail it will have a cap on it and when you take the cap off there is a valve core in it like on a tire push the core in and see if gas sprays out there if no fuel pressure the fuel pump may have failed, sometimes you can take a hammer and hit on the bottom of the fuel tank and the fuel pump may work and if it starts get it to where you want it because it may not start again. If you have fuel pressure at the fuel rail and it dont start you may have a security problem is the securtity light on? the fuel injectors are disabled on some GM vehciles when the security light is on

Computer showing any codes? Could be a bad regulator or a leak in the system allowing air in and fuel to flow back to the gas tank.

My 92 double cab mazda b 2600wont run unless you pore gas into inlet manifold. any one have an idea . the motor is injected


This sounds like your electronic fuel pump is bad.Check fuel pressure by purchasing a inexpensive kit around 10 to 15 dollars. Disconnect fuel line by the fuel rail. Install your tester.It should read around 30 psi. Also check filter element.
