How many volts are the fuel injectors supposed to get ?


Recommended Posts

Hi. I'm troubleshooting a problem where my 2000 C2 Tip cranks but won't start. Fuel pump pumps fuel, so I started thinking maybe something to do with the fuel injectors. If I remove the 30 Amp fuse number 2 from row C under dash (fuel injectors and oxygen sensors) then turn the key, the voltmeter I attach to the fuel injector fuse leads say ~7 to 8 volts (battery gives 12). Is that something to look into.

I'm not sure on your engine but on older vehicles the injectors operated on system voltage which was 12-14 volts. I don't think your testing the circuit correctly. How are you testing for injector pulse? The cheap and easy way is to use a noid light which you can purchase for a few dollars. It connects to the injector harness and just crank the engine and watch for the light to flash with each pulse.
