fg conversion pats removal

[bogga]

I have a fg barra (HAEDJJ4) conversion in a patrol that has come in to the shop unfinished and not starting. Someone has put a base file in but pats wasn't off correctly so would crank and no fire. I think because of this the fuel pumps been wired directly to a switch. Ive switched both pats and now it fires but drops inj pulse the minute it fires and stalls. Its a manual and has no other modules etc connected. Ive checked the ecu powers and grounds and making sure all the +12v arent dropping out when cranking ór something silly like that. I've read on here the fg needs an abs module for a speed referance so doesnt go into limp mode, this doesnt have one but wouldnt have thought stationary with no speed sensor would cause an injector cut issue. I did find the map sensor wasnt reading correctly so switched turbo logic and this is what allowed the car to actually fire and seem to run for the few sec what seems normal before injector cut and stall? anyone had this before or have some advice?

These are generally nightmare jobs. Have a chat to Brett at Custom Machine Works or Bill at Everything Barra. They have a lot of experience with conversions.

I had a similar problem make sure the 12V source to ECU is not just when cranking but when the key is also in the run position.

Got it sorted, was just manual/auto switch causing the issue.
