I've got a 2013 Silverado LS 5.3L paired with the factory 6L80e transmission, ive had the motor firing and actually had it running sitting on an engine hoist, but it was just off ether through the throttle body. I'm getting no injector pulse on any of my injectors.
I've already gone through and disabled both VATS and the starter check, is there anything else I would need to alter to get it to shoot fuel for me?
I dont have the set up in the vehicle yet so I dont have any lines ran or anything, no fuel pressure on the rails, no cooler lines ran. None of that. I wanted to make sure I could have the motor running prior to bolting it into the jeep, now i apologize if this is a stupid question but will not having fp cause the injectors to not fire? I've checked my grounds, all injectors have 12v+, all my coils fire(like I said i had it running with ether) I believe everything is squared away but I want to ask before I go and bolt everything down and start getting lines made for it all. I couldn't find a definitive answer because every post about no injectors state that there is fp, ive got test lights hooked up to the injector plug-ins so I know they aren't firing, nor do they click while cranking so there's absolutely no firing on the injectors, and for peace of mind I wanna ask if no fp will kill pulse.
