2001 vw passat, remote start

Hopefully you can help. I installed a viper 5101 today on my b5 passat pre immobilizer, i believe i installed it correctly but i cannot get it to start. it has a quick pulse to starter wire but it doesn't seem like its giving the voltage long enough to start. So far i have checked the neutral, hood, 12v constant, ignition, tach and just about everything else i could find on the web. i also have a bit writer to check settings, changed and turned off tach, tried to increase crank time, and zap the unit to start fresh.

Thank you for any help you can provide.

Also tried with the key in the ignition.

Didn't keep my spacing, but hopefully you can still read it.
Also don't get any flashes indicating a problem.
Just tries to start for a milli second over and over.

Are you 100% sure that vehicle does not have immobilizer? Have you tried placing the key in the ignition without turning it and r/s?

Yes I have tried with the key in the ignition. Still does the same thing.
Thank you

did you try disconnecting the viper hoodpin wire from the factory wire? I have seen instances where the factory hoodpin spikes just enough to kill remote start. Is the viper flashing the parking lights when it shuts down/doesn't start?

Yes I am not connected to the factory hood pin at the moment because it broke off at some point and is taped closed right now. I have the viper hood pin wire connected to ground with the neutral safety wire. And the unit is set to normally closed option. No I am not getting any flashes. Just the alarm just keeps trying to start for a milli second over and over again.

Does anyone else have any suggestions.

Why would you have the Viper hood pin wire connected to ground? Plz disconnect this wire and try to remote start the car.

After the split second starting, does the dash stay alive for 5-10 seconds?

No question is stupid or not worth asking. You were once a noob, right? :)

If I disconnect the hood pin I get six flashes indicating a hood shut down. I can program the hood as normal open or normal closed. Right now it's closed. Tried both ways though. Thanks for the input

I don't know if it's 5 to 10 seconds. But it just restarts the start sequence. I can check though in the morning. Thanks

No the lights immediately shut off after it fails to start

Are your connections soldered, crimped or scotch locked? Sounds like a loose connection to me.

Soldered with heat shrink. Do you think its the starter wire loose or can any random wire cause the problem?

Found the problem. It was a bad ground. Thank you everyone for your ideas.
