I just finished doing my 1.6 rocam. When i started it it picked up revs on its own i switched it off. When i tried starting again it didn't. I checked the power on the injectors using my probe tester
I used my probe testers on the injector harness
plugs in those two pin plugs there's only 1 that
showing the live when the ignition is on. But when
its off the negative is very faint on the same one
that was live but the other one shows nothing. And
now it only starts when i spray it with the quick
start on the throttle body. If i stop spraying the
Engin dies also. What could be the problem?
The one pin on the injector is the Ignition voltage (Nornally 12 V). the other pin is the neg and is earthed in the PCM at a pulse width rate of between 0.05 and 9.0 Ms. You can not really neasure it with a volt meter , but by using an oscilloscope measuring pulse width. Check that the Impact switch on the left side under the dash mounted on the A pillar has not tripped and switched the pump off.
Ok i'll check but the fuel is coming i see that when i opened the fuel return on the common rail. But i'll definitely check the switch. Thanks boet.
