Viper xv791 remote start problem

I hooked up the tach wire correctly.

Only time my car will remote start is if I have the key at ON position. 

Wether remote start toggle switch is on or off, remote start will try to start the car but doesn't actually start.  Car keeps cranking but doesn't catch.

do you have the second starter wire hooked up correctly?also on the ignition 1 did you use the smaller gauge BLACK/ red wire?the starter 1 will either be BLACK/ RED or BLACK/ WHITEalso the 2 accessory wires?

There's only 1 accessory wire which is Orange from alarm.  There are 2 accessory wires?

I cut thicker (BLACK/ red - starter #1) wire in half.  I connected green wire from alarm to harness side.  I connected the purple wire from alarm to the other side.

I cut (BLACK/ blue - starter #2) wire in half.  I made a jumper wire which connects from purple wire from alarm to this BLACK/ blue wire.  I didn't connect it to the harness side but the other side of the cut. 

I connected pink wire from alarm to thinner (BLACK/ red - ignition).  I connected pink/white from alarm to (red - ignition #2 ??? )  Not sure if the red wire on ignition harness is ignition #2

I connected orange wire from alarm to (WHITE/ blue - 2nd accessory)

I connected the red wires from alarm to (green - 12v)

After playing around a bit, I got to a point where car starts only if I have the key inserted.  If I don't have key inserted, my remote start won't work.

There is something wrong with your 555U. Check your wiring and placement of your cylinder ring.

ok the second starter needs a relay- use the trigger wire from the 4 small wires off the acrs pack- purple second accessory use another relay and use the orange off the xcrs do not connect it straight to the wire the second starter should not be cut the 4 wires from the xcrs that are small gauge are relay trun on wires and should not be directly connected tot he wire in the car without the use of a relay also check the bypass that it is mounted correctly around the cylinder.

Are you suppose to keep your valet key in the 555U?

yes or else the car will not remote start it will remote start if you have the key in the ignition cylander

If remote starter works w/ either ON and OFF remote start toggle switch, is there problem w/ the swtich itself or wiring problem?

See if you can go into programing if you can than the valet button is working , after that I would try to program the unit for voltage sense . This way you can see if the ring is in the right place .
