where on a 1995 ford f250 7.3 engine is the number 8 fuel injector located I have hod a buzz test done on the truck thay said the number 8 fuel injector was not working so I need to know wrere is the number 8 fuel injector is located
I had to replace the injector itself the other day as it was not allowing the fuel to go into the TBI unit. I used the injector test light on the harness and it show the computer as being good.
you have to remove the high pressure oil manifold, then remove the fuel injector.
There should be a fuel pressure "test" port behind the throttle body. Test the fuel pressure at the test port using a fuel pressure gauge. If the engine starts using starting fluid and doesn't start without, and the fuel pressure at the test port is normal... you have something else going on. It COULD be the injector, but don't assume until you've tested other stuff.
under hood, on fuel rail which is connected to each fuel injector there should be a valve that looks like a tire valve. That is the shrader valve, test fuel pressure there.
A noid light is there to test the electrical impulses in your fuel injector. The noid light helps determine a misfire.
There is a noid light that will check injector pulses from the distributor. It plugs into the injector plug. Most common failure for inop injector is in the distributor module. Also check fuel pressure to see if the fuel pump is operating correctly. It should come on for 2-3 seconds when ignition key is turned to run. Chevy guy denver
Bad oxygen sensor, fuel injector bleed, timing off.
This is caused by your PCM being unable to adapt enough to correct a problem in the fuel/air mixture. This can be caused by several things, not necessarily in this order. Catalyst plugged Bad Powertrain Control Module Engine parts tolerance Fuel injector(s) stuck open or leaking MAP sensor O2 sensor (upstream) Fuel pressure regulator Wiring harness/connector problem
There are several ways. Most people use what is called a noid light. To use a noid light you unplug a fuel injector and plug a noid light in to the harness. You turn the engine over. If the noid light flashes then you have injector pulse. Another way to check is to use a low wattage test light. Unplug a fuel injector, and plug one end of the test light to each wire from the harness. Crank the engine over and see if the light flashes.
If you are using a test light and testing the ground connection with key on, the test light will light up because you are completing the circuit not because you have two positive wires.
On top of engine you will see a metal line that feeds fuel injectors that is your fuel rail it will go around to each injector on that line you will see a fitting where you attach a pressure guage
