Audiovox Remote starter gone haywire

Helo all I'm a newbie to this forum, and hope I can get some advice on my remote starter issue.

I've got a 2002 Mazda Protege5, automatic transmission.

Bring it back to the dealer that installed the alarm/remote starter and get them to look at the tach signal wire. It seems that the unit can not tell if the car has started and also  is shutting down because of a lack of a tach signal. Another possibility is that the  immobilizer bypass is not functioning properly and that's why it's shutting off on you. Get them to check this as well.

Well, I think I checked the tach sensing wire myself, as this has been suggested to me on several forums.

I found one wire connected to a coil pack on op of the motor - this wire seems to have been extended, as the original wire is GREEN/ orange - it seems to "change" to a BLACK/ white wire, but is the only wire present on the coil from the alarm/starter.

I remote started the car (which, BTW, is no longer giving me trouble - it ran just fine - go figure) with the hood up and the pinswitch taped down, and pulled the wire off of the coil, and the engine kept running?!?!  Shouldn't it shut down?  Is it possible that the wire I pulled (which runs straight from the coil to the alarm wiring under the dash) is not the tach input?

Now my real problem is that he starter is not acting up anymore, so I don't know how it could be tested, diagnosed and fixed - the problem won't appear if I bring it in for service.

I'm a little unsure of what to do next....bu thanks for any replies - they do help.

Regardless of wether or not it happens again when you bring it to the garage is not the issue. It's best to be able to bring this up to the dealer when things like this happen, especially when your car is still on warranty. If the problem was evident before and you know it happened, you can bring it down to the dealer and most computer systems on cars these days hold errors when they occur for technicians to diagnose at a later date. Seeing that the dealer installed the starter..... they are ultimately responsible for the installation and also the warranty if the alarm/remote starter is the cause of the troubles. Better safe than sorry and bring it up to them now..... they might be able to fix something with it.

If the tach wire was taken off the car before you remote started the car, the car should not have started., but because you removed the tach wire after the car started, it should still run, but some RS units only require it for startup and after that it only needs it for monitoring if the revs get up too high. So if it's not there while it's already started, then it's not too high rather too low or 0 so it will not register on the CPU of the module.
