Installed a Mannix SM700 remote start on a 1997 Chevy Tahoe.  Everything seems to be working fine excect the remote start.  I have use the Tach learning feature for the transmitter, but it's still will not start.

Any experience with this alarm?  Any suggestions.

There is no passlock system on this particular year.  I believe that the problem is with the alarm.  The tach learn is acknowledging my tach wire, but the alarm does not even attempt to remote start when I press the transmitter button.

Any suggestions, as I ready to throw this damn alarm in the trash.  This always seems to happen when I get away from the DEI family

When you say it will not start, does it crank? Does it attempt to start and die?

Did the tachometer programming verify that it learned?

The tachometer programming verified that it was learned.  The remote start is not even attempting to start.  When the button is depressed, the alarm chirps three times, and nothing else happens.

Have you tried to remote start with the key in the ignition?

Did you check the hood pin? Is it reading tach before crank? Is it in some crazy valet mode?

I have not attempted to remote start with the key in the ignition, but I'm certain that this particular year Chevy does not have the passlock system.  In addition, the alarm does not even attempt to remote start.  As stated above, it only chirps three times and the parking lights blink three times and nothing else.

I did not connect the hood pin.  Is this one of those alarms that require you connect the hood pin in order for it to operate properly?  An alternative would be to sent the hood pin wire to ground right ???

Um, no. Grounding the hood pin is not what you want to do. the hoodpin is a negative trigger. What happens when you ground a negative trigger?

The hood pin is a good idea so that if anyone is working under the hood they cannot inadvertently activate the remote start. Check the manual for the starter and see what the significance of 3 flashes is. This may give you some insight on what/where your issue is.

Keep us posted.

I have gone throught the entire user manual and installer mannual and no such luck.  I know that I'm missing something simple, but I can't seem to figure out what it is.

I am not familiar with the Mannix unit so I am just going to throw this out there for you. I was installing a TRC branded remote start in a Saturn Relay, the brake switch was providing right around 2 volts at rest and then 12 when the switch was activated. This TRC system was actually reading the 2V and not allowing the system to start. I put it through a relay and the system worked fine. The voltage was not enough to trip the relay, but was enough for the POS TRC system. Try disconnecting the brake wire from the starter and try to remote start it...keep some type of way to shut it down accessible like maybe hold the hood pin wire close to ground and if the starter gives you a problem ground it to shut it down while testing. Again, I am just throwing this out there for something else to test.

Keep us posted.

This may be worth trying Twelvoltz.  Everything that I have read about the alarm in the user manual and installation manual indicates that I need to double check the neutral safety wire.  I'm almost 100% certain that I sent this wire to a ground.
