viper 5904 will not start by key

I am attempting to troubleshoot a viper 5904 + iDatalink module (via D2D) in my wife's 2012 Honda Civic LX. Everything is installed as of two days ago. Everything alarm related is functional. On the remote start side.. not so much. At first I was having issues with the car not cranking at all during the remote start process. The remote would say it is starting, the car gauges would light up but and the viper unit would click but nothing else. My current issue this: While fiddling with it tonight making sure the idatalink properly flashed/programmed for my configuration and pondering the possible issues. I attempted to start the car via remote a few times without success. I then attempted to start the car by turning the key in the ignition... nothing.. I figured maybe I ran the battery dead. Not the case. After sweating bullets for a while and jumping the starter wires purple and green at the harness that plugs into the viper unit then turning the key.. it fired right up. I'm thankful it did because I did not want to explain to the wife how I fried her brand new car. Is it possible that the remote start is fried within the viper unit?

Need more info.  Which iDatalink bypass module?  Some only handle the transponder bypass while others will do that and a whole lot more.  Additionally, most require a special firmware flash (DBI vs ADS firmware ) to go D2D with a Directed system ( Viper, Avital, etc ).

Have you installed Viper systems before?   The H3 harness can be tricky ( wire labels vague ).  The Neutral Safety setup and the Manual Transmission Mode default are other poorly documented areas.  Listing your H3 connections for forum members to check is a good start.

Have you tried to check the Vipers Shutdown Diagnostics?   This will give you an idea of the remote start failure.

Can you enter into PitStop mode?  That will verify that most of the ignition wires are correct.

Have you connected the Tach wire, programmed the Viper to Tach Mode and performed the Tach Learn Process?  That is the most reliable way to remote start an engine.

Soldering is fun!

Living and learning.. So.. I was thinking about what I could have done to f#ck this thing up.. I read the install manual and it says "Never use a test light or logic probe when installing this unit. Always use a multi-meter." I used a test light to check for output on the   H3/4   Violet   Starter output (car side of starter kill) wire. Probably fried it. Any possible way to repair this? (Aside from purchasing new unit)

Actually, the only safe place to use a test light would be those thick, high current, ignition wires.

Your Viper should be OK if that is all you used the test light on.  Usually it's the vehicle and its' delicate computers that get fried by test light use,  As long as the Civic is working 100% OK by the key, you should be fine.

Perhaps if you listed your H3 wire connections...

I have not read anything about H3/9 being used. Would you happen to know how/where to go about connecting it?

So, connect H3/7 to red and H3/9 to white then set it up for flex relay in settings. Right?

Yes. 

H3/7 supplies power to the Civics Accessory2 circuit.H3/2 supplies power to the Vipers Flex Relay ( ACC2 ).H3/6 supplies power to H3/1 IGN1 relay.H3/9 supplies power to the Vipers ACC1 and Starter relays.

While ACC2 might be optional and not an issue when trying to get the Viper to crank the engine,

H3/9 is very important.

Your the man. Thanks. Do you think the car will fire by key once all this is properly connected? Any ideas why it did fire and now it does not? Might be a few days before I get around to correcting the wires. I'll keep you posted. Thanks again for the help.
