Remote Start DIY Wiring Guide 2006-2010 Yaris

I've go an interesting issue. 2007 Yaris sedan, no factory alarm, no engine immobilizer, power locks. I followed the DIY PDF to install 1172 Ultra Start. Had remote lock/unlock functionality with park lamp flash using either of the two fobs, but remote start did not work when I pressed the star button and the horn did not sound with any command. The strange things is that it would remote start intermittently when I pressed the star button, then lock button.

I entered programming mode and was working through the lock button menus when the car suddenly started but never disengaged the starter . I tried pressing the brake then turning the key to OFF (normal to stop remote start functionality), but that didn't work. After some panic, I pulled power to the remote start module. Now every time I apply power to the module, the vehicle instantly cranks, but won't start. I have the hood up (hood switch open) and key is out of ignition--doesn't matter. Continuity is good on the black starter wire to yellow wire from remote starter module. None of the wires of the 6 pin remote starter connector are shorted to ground (continuity checked). Is there somewhere I can check to see if the module could be giving ground when it shouldn't. Please help!

It sounds like the relay for the starter is stuck closed. Try giving the remote start unit a good hard slap with your hand to see if it will unstick. Even if it does, I would not trust it and would get it replaced. I recently went through two bad units before getting a good one, with a Viper remote starter that I installed for a friend.

I gave it a few solid slaps this morning. No luck. I'll contact Ultra Starters and see if they will warranty it. Have you had luck with the manufacturer replacing the unit under warranty in this scenario?
