astrostart 2100 problems

Hello I just bought a new vehicle and it has the astrostart 2100 in it,when you try to start it,it will just start and shut off right away,then everything goes off then a few seconds later it will try to start agian, same thing happens it does this 3 times and then there is nothing. there is no lights that blink on the unit.

Any thoughts? Looks like there is a brand new battery in the vehicle could that have something to do with it? Also tried to put the key in the igintion and try and same thing happens?

Thanks

Try placing the key in the ignition and turn the switch to the on position.  Then attempt to remote start it, what happens now?

Same thing happens starts and shuts off right away, I can start it with the key and then push the start and it will do the contunious run, like it should then I hit the brake and it shuts off like it should.

DId you turn the key to the run position?

You need to investigate the Tach wire connection.

Were is that located? I might just bring it in
