New Problem*
Okay, I did the starter Relay enable trick, but now a day later the car does a intermittent stall out, the fuel pump shuts off every few minutes, the SES does come on and stays on for short time, until the car shuts off for a few minutes, then craps out, it is the fuel pump that cuts out, so what am I missing?...I had to leave my car somewhere else, but will go to tow it back tomorrow!...I wonder now If I need to replace the crappy Starter enable relay and remove the bypass wire?

Re: New Problem*
How's your ignition module? as i found out, the purple and white wire hanging off the ICM controls the fuel system. I had a weird intermittent issue like this where the fuel pump would die without warning, then some time later start up again only to die once more.

Re: New Problem*
This happened the day after the VATS Starter enable relay crapped out, I replaced the relay with a single wire bypass, I wonder is that is causing a new problem?

Re: New Problem*
It may be that the VATS/pass key module is acting up. This senses your resistor in the key and if its right enables the ground to the relay you bypassed, it also sends a signal to the ECU to enable the fuel pump and injectors.
So either your contact on the resistor in your key is dirty, the contact in the switch is dirty/worn, or the module/wiring has a fault in it. Since its intermittent I'm thinking the contacts in the key cylinder as you drive are loosing contact to the resistor to your key. If this is the case you can do the resistor trick and bypass the key sensor.
Easiest thing to do is to completely delete the VATS/passkey https://www.hawksmotorsports.com/vat...maro-firebird/ or have a tuner re program your rom in the ECU to disable VATS. Then remove the starter disable relay or at least take the ground wire directly to ground. Then remove the bulb for the "SECURITY" light in the cluster (or pull the fuse to the VATS module).
Similar issue as this guy https://www.thirdgen.org/forums/elec...7692-vats.html
