no start with dbw plugged in Hey guys
This is going to be a head scratcher. Building a 1972 cutlass with the ls3 erod connect and cruise setup and it went in fine, started up fine, drove fine (for what little I did because car was not finished), but out of the blue it stopped starting. Through testing, the injectors will not fire if the throttle body or the pedal are plugged in. If I unplug either, the engine will start as it should and idle fine.
With the tb and app plugged in, watching the tb on scanner, it is functioning; but will not fire the injectors. It is throwing no codes while everything is plugged in.
Help! This one has me banging my head against the wall.
Tested both the tb and app and both are within proper range for resistance, both have 5 v ref. Am I looking in the right place or is this trying to point me elsewhere?, March 2, 2023 Friday, March 3, 2023 Saturday, March 4, 2023 Sunday, March 5, 2023 Monday, March 6, 2023

I've personally not messed with dbw but I once had a tps that was wired backwards and wouldn't fire bc 100% throttle won't fire injectors. Can you see what % throttle you are at with it all plugged in? Maybe it's putting it to 100? Are you sure the injectors aren't firing?
