Viper 791xv 2000 grand am gt

I have a 2000 grand am gt, I installed the whole system on it.  But when I goto start the car, it just starts and stops three times.  I installed the same one on my 98 chevy pickup and had no problem.  I installed the bypass module and everything.  I checked the tach to see if it works, the led blinks to set it, so it works.  I checked the wiring 4 times to match it up to the specific wires on the diagram that i got form this site.  i have no idea what is going on.  Please help.

It sounds to me like a tach signal problem however we have experienced some of the same problems with our junior installers.  Find the exact problem by process of elimination.  Make sure is by-pass module is engaging during the crank-up.  Double check your ignition connections-accessory wires from the 791 do not send 12 volts until AFTER the starting process.  Check your voltages AT THE 791 harness to ensure a good connection.  Hoped I helped some. 

Good Luck
