01 4runner & Viper 771XV

does it try to carnk? do the dash lights light up/ need more info on what it's doing when you pres the * twice.under promise and overdeliver

does it crank, dash lights light up?what exactly happens when you press the* twice?under promise and overdeliver

Nothing happens at all.  I even tried programming the unit so that you only have to press the * button once and to watch the voltage, but that didn't help at all.

I don't think it is the Key Sense:

Ign Key Warn

YELLOW/RED (-)

AT KEY CYLINDER SWITCH

Tach Signal

BLACK OR BLUE

AT ECM BEHIND PASSENGER SIDE DASH

When you Remote Start, does the Viper show output to the Starter & Ignition?  Or does it not make any noise?

I did this one time when i had a huge hang over, i did a ouple bad sodders and the connections to the remote harness weren't good. Nothing happend. Take a Muilty Meter and test every wire and you could have also connected the wrong wire as well.

Double check that none of the shutdown inputs are active:  GROUND at 22 ga. Gray hood pin, 12V(+) at 22 ga. Brown brake input, or lack of GROUND at 22 ga. BLACK/ White remote start enable input (toggle switch input) will inhibit remote start activation.  Then confirm that you have Ignition (BLACK / YELLOW) AND 2nd Ignition (BLACK/ Red) connected to their respective relay satellite outputs.  A factory keysense is a possibility, but I wouldn't bet on it considering that in a normal installation in which the factory immobilizer is intact, the vehicle starts once the correct wires are energized and the bypass module's output signal is read, with no other "hard-wired" type of interface involved.

if nothing is happening and the keysless works then the black with a white stripe is probably not groundedunder promise and overdeliver
