    i have a multimeter. I put it to the connector that plugs into the injector. You mean i should test the injector itself while it unplugged.

  • mrfortino Dec 30, 2008

    i tested it and all the other ones read what your saying. but the # 1 injector is reading nothing!!!

  • mrfortino Dec 30, 2008

    I find it hard to believe that 5 of them i took from the wrecker don't work either.. but anything is possible i guess.

Not unusual to loose an injector , have you put an ohm meter on the injector while it is unplugged , believe you should see 11 - 13 ohms , do you have a noid light tester ? compare ohms to a good injector .

93 altima same fuel injector goes bad 2 times in 1 month


how did you find out it is the injector causing the problem? the injectors are wired in series on these vehicles, it is possible that another faulty injector may be causing the problem. although it may be difficult to find if this happens intermittently. A scope test may be the only way to find the problem. Does the engine light come on with a misfire code on Cylinder #1? P0301 or r u just getting a random misfire code P0300 ? a bit more info on the vehicle may also be helpful........ engine size? # of cylinders 4 or 6 ?

The fuel injectors stopped pulsing on my 94 pontiac grand prix se what could be the problem


The injectors get a ground signal from the computer. If all of the injectors have voltage but no ground from the computer, either the driver in the computer is toast or the computer is not getting a timing signal from one of the other sensors ( crank - cam )
Check the computer for trouble codes first.

94 nissan altima 2.4 runs well until it reaches normal temp, then dies, ( no spark @ coil/dist). once it cools, it starts and runs fine.


maybe your fuel injector is clogged-up so try filling up 8 oz. of fuel injector cleaner 1st and let your car run for few minutes to eliminate all the carbon that builds -up inside fuel lines to the exhaust. also try testing your battery maybe dead already. use a tester then start the engine measure it. set your meter to 15 VDCor above as long as more than 12vdc for security. put he red needle to red positive of hte battery and vice versa black needle of the meter to your negative of your battery. the reading must be appx 12. 4 vdc + And then try accelerating by stepping on your gas pedal to around 2- 3000 rpm (3 x 1000) on your dash gauge. the reading must be around appx 13.8vdc or 14.2 vdc. therefore your battery is good if you see thsese results. also try distributor cap replace ,spark plugs mostly before sparkplug cables then ignition coil.
