LS3 swapped Fireberd

[akalshaikh]

I am working on a 2001 Firebird that has an LS3 swap and lingenfilter x58 to x24 converter. The light on the box it self stays steady green while cranking meaning it has a steady crank and cam signal. I dialed in the injectors as per the green and yellow sheet, VAT disabled and went to a point where maxed out the injectors but the car does not run. It keeps cranking only.

We checked voltage on the injectors connector and they are all good. I get 0.5v ignition on and bumps to 2.2v while cranking. However, nothing comes out of the injectors at all not a single drop of fuel.

I've attached the tune file hoping someone can shed some light on the issue going on.

Is it from the converter that its not triggering the injectors or is it a tune related issue!!

I do get RPM while cranking and actually it ran fine when we sprayed some fuel into the intake.

It's not the tune or the conversion box.

Is the fuel pump coming on? Have you verified fuel pressure?

You should get 12V to the pink wire on the injectors with the key on and during cranking. If you don't, start checking fuses.

Fuel pressure is good, i do get fuel all the way to the fuel rail. Fuel pump is working fuel pressure is 55ish psi.

I will check the pink wire today and will update the post

What is the PCM voltage during cranking?

[Pekka_Perkeles]

What is the PCM voltage during cranking? If it's below 10 volts it will do cranking but does not start.

A log would be nice.

I did not check that

I will check and confirm. I'll upload a log too

Attached is the log file. I couldn't read or log the control module voltage for some reason!!

Did you ever get 12v at injector pink wire?

Yes, i do get 12v to the injectors on the pink wire.
I am starting to wonder if its from the lingenfelter converter

[Shnraines]

If it runs when spraying into intake, the converter is working. Vats maybe?

Vats already been disabled. I have my tune file attached too.

I tried hot wiring the injectors giving them 12v direct and that didn't work.

Now for some reason, only cyl 2 injector is working.

Update:
Car started and running perfect., Refreshed the injectors, dialed in injectors scaling again and started from first crank

[Shnraines]

What does refreshed injectors mean?

[akalshaikh]

What does refreshed injectors mean?

Cleaned, new seal, new strainer and bench tested them.

[Shnraines]

Were they clogged?

[akalshaikh]

We believe so, He did the injectors and went through the wiring all over again. He found a ground which was loose and the map sensor wiring was wrong although it was reading.
