What causes fuel injectors to not spray gas but the fuel pump works and it has gas in it?

chevy s10 v-6 changed the distributor and the only way it will run is if you put gas in the carburator. it is the injectors in the carburator.What causes fuel injectors to not spray gas but the fuel pump works and it has gas in it?Bad injector or you could have not connected the wire to the injector back on when you where working on the distributor. Look for a wire that you disconnected and forgot to connect. good luck

Possibly a wiring problem or completely plugged injector.

#1 fuel injected engine do NOT have carburetor. They have throttle body.

There could be few reason why you have the problem:



(1) no signal to the injector

(2) clogged fuel filter

(3) clogged fuel injector





Good Luck...
yea check the wiring going to the injectors sometimes the little plastic connectors just loosen up or the tbi(carb)metal sheth/spacer rubs (or the wires them selfs)against the wiring where the little rubber part is(where the 4 wires come together)



a tester will tell you if the injector is not firing or if you have a fuel issue



goodluck
You must be referring to throttle body injection. It looks like a carburetor with a fuel injection nozzle in it. Fuel injectors are basically electronic devices and sometimes, they fail. If you have a throttle body, it's more obvious because it doesn't have an injector per cylinder which in general would allow the car to run on the remaining cylinders. You can get a shop manual and check the injector, but in general, it seems to have just failed. Does it actually run or just make a noise? You may not have installed the distributor properly. It could be 180 degrees ) or some other number of degrees) out. If it was running when you took the old distributor out, double check your installation and repair. As is often the case on here, you don't give a lot of detail that would help diagnose. Good luck with it.
in that situation, the computer controls the injectors. if it starts when you prime the throttle body, the ecm is bad, it has lost the timer to prime the pump.
