We can bypass it if needed. You would have to send us the PROM chip and then you would have to wire starter relay to ground.

pretty sure you get a light on your DIC when you try to engage the starter and vats is on.... if it is vats, usually locking and unlocking the passenger door will do it.....otherwise, start with a fuel pressure gauge ....hopefully an fsm....good luck.......

I ran the codes everything was good put a pressure gage on fuel had around 60 psi thats good , could be the ignition module will try that already replaced the coil. This isn’t a L98 motor its a 383 with mini ram AFR heads and its been on a dyno 3 times before they got the tune correct.
