Car starts in cold start injector and the die

[carlospena96]

Hello again, here I am again with this problem since 3 months ago

The subject says everything, car star in cold start injector and the die, this is a video

The car has a good spark, and it has a good fuel pressure, I guess the injectors don't inject, I need help

You need to get a multimeter and test the FI components. Not sure what else to tell you - test the electronics and let us know what you find.

I test the fuel injectors connectors with a light probe, and for some reason there's no pulse, the 2 pins give me light but no pulse

[narfire]

Two grounds for the injectors connected to the intake plenum?

[carlospena96]

There's 2 wires of ground pluged in the intake plenum, I cleaned both, but still same problem

[carlospena96]

I put the noid light in injector connectors, give me light in both pins, even I crank the engine, for some reason there's no pulse

[divace73]

is the tach line for the FI system connected?

[carlospena96]

What's the color of the cable? I know there's a yellow and brown/white plugged on the negative side

[divace73]

I think it is sheathed in black and from memory has an extra lug so you can piggy back off it??

[carlospena96]

yes, it is sheathed in black, and it's plugged in the negative side of the coil

[divace73]

okay, is that pulsing with the rpm as you start the car?

[carlospena96]

I test the connectors when cranked, the connectors has power, but i got no pulse, i check every pin in every connector, It's something in the ignition that give the pulse on the injectors?

[divace73]

yes, the way the system works is that everything is based on getting the timing from the coil, it uses the timing and all the other sensors to determine how much fuel is injected. The cold start valve works independently.

Which connector are you referring to?

Can you disconnected the cold start valve and see if it kicks over the same?

Did it work normally at any stage?

Did you by chance remove the engine to body earth cable?

[carlospena96]

I reffering the injector connectors, and when I disconnect the cold start injector the car cranks but not start

[divace73]

do you have a multi meter and have you gone through Brads FI document?

When was the last time the car ran normally? if everything else is working, all earths are correct and the ECU is getting a pulse from the dizzy and you can measure 12V on the injector it would point to either the injector is stuck or gummed up or the ECU is not working...
The ECU's rarely fail and it's hard to believe all the injectors would get gummed up....just a thought, have you used any ethanol mixed petrol at all??
