Topic: GM Passkey II-- can it be ELIMINATED?
Can the whole passkey II / VATS system be eliminated? Is it a separate security-type relay that can be jumper wired, or is it actually part of the whole ecu box thingie? We've installed a resistor of the proper value to eliminate a faulty ignition key pickup and still no good.
Verified that there is a 5v signal to the wires without the key in ignition and without the resistor connected yet.
We could periodically get it to crank, and the passkey light to go off, but there didn't seem to be a rhyme or reason for it. It would just happen all on it's own. And then stop cranking. It seems random, but perhaps if someone can give me a pattern to look for I can be better equipped to check for proper sequence and operation.
It's a 96 fleetwood, super super low miles so sitting most of it's life.
Could a bad fuel pump be backfeeding power and screwing things up? Fuel pump seems to be confirmed bad because the red test wire does nothing to it. Full tank of what smells like varnish. Plan is to either drain/drop tank or maybe just cut an access hatch in the trunk like the firebird guys do.
