remote start not starting on first crank

I know this is going to sound weird but i had a problem before where i went to remote start the car and it cranked but didn't start. the sequence shut down and goes for a second attempt. during the second attempt it starts. i was using a dei alarm with a code alarm transponder bypass box. i realized that the code alarm was a piece so i ditched it and hooked up a dei transponder bypass. Everything has been fine since then (5 months ago) until i went to start my car in 34 degree weather and it did it again. Same thing---won't start during first crank but starts fine on second crank. Once the car warmed up the remote start worked fine every time. My question is....Is this problem being caused buy the transponder not getting signal or by the secod starter wire. What exactly happens if the second starter wire is not hooked up? Will it still crank in cold?  Thanks, Marc

first...what is the year make and model?  has this ever happen with the key?  and is the tach wire hooked up?  if the system is using a voltage sense then this could be ur problem......Where theres is a wire there's a way.

i had this with a car recently. The only cause that i could find was that the tach was set too low. To cure it i set the rpm when the car had just started and the choke was on. It was sitting at about 1300rpm at this point. Now when its cold it always starts first time.

The same thing happens to me especially when it gets cold. I do have the tach hooked up. It's a 92 S-10 4.3L automatic.    Since it starts fine the second try I never worried too much about it. On very rare occasions it's failed to re crank and I have to hit the button again.

hook up the second starter circuit as mentioned... if it already is, or this doesnt correct the problem you may want to increase the crank time slightly....Kevin Gerry
