1995 Chevy 3500 not getting gas I'm getting gas all the way to throttle body. I have tried 3 sets of used injector same response


Is the pressure regulator operating? You need at least 30 lbs to fire an injector and make sure the check valve it it maintains 30 lbs with the engine off.

Injector issues.


Well, if you have a ground signal on one injector and not the other, the ECM is not grounding it.
If the plugs are firing on those cylinders, it may be the driver in the computer. The computer uses the same signal from the distributor that fires the plugs to pulse the injectors.
If those cylinders are not firing, it could be the pickup coil in the distributor or the module.

No fire to fuel pump key faul light stay on


If the key fault light is on, it is most likely the anti theft security shutting off your fuel to the injectors. If this is the case, you can bypass this system to get around that anti theft. http://vatspasslockpasskeysecurityhelp.yolasite.com/

Fuel injectures wont fire in my 95 chevy 1500


Do you have fuel pressure? Buy or borrow a noid light, it plugs in to the injector plug and lets you see if the injector is getting the electrical pulse it needs to work. If the noid light flashes you need to look at fuel pressure, bad pump, clogged filter etc. If it doesent flash look at the ecu or distributor pick up

You mean no fire/spark. replace your distributor cap and rotor. If your injectors are not pulsing, then it may be computer related.
