weird problem 1997 Toyota Camry

Car remote starts fine when the heater controls are off, but when you turn the heater controls on the car won't remote start, it just cranks, I am using a command start 380I, yes I am powering the second ignition properly

I have never seen this problem yet in my couple years of being an installer

someone please help

Thanksyou

figured out the above problem

Now the car starts with the remote, turn the car off and then I try it again and it doesn't start, I reprogram tach and then try it again and it works pefect this happens over and over again

I got the tach off of the fuel injector using a blue wire on one of them

I would want to verify the Connections also:

That is why I would verify all connections............The first Post sounds like a wire was not correct......The TACH issue sounds like a MEMORY issue, which sounds like wrong wire..........

who knows ...could be the unit
