1986.5 starting problems...??

[projectsupramk3]

Why'd you post in this guys thread? Anyway it's definetly the alarm's starter cut, you locked the doors with the key from the outside, or did you push the lock button on the inside. You have to lock and then unlock to doors with the key (wait 30ish seconds for the alarm to activate and the red LED to start blinking) or the starter cut will stay on.

Hi new to the forum here. I have a 85 supra with the same problem. I have tried all of what you have said. I cannot figure it out. What makes the alarm go off in the first place? How can I disable it? Can i take it out? Please help. This problem has made me late to work to many times.

I am about ready to sell this car, if I don't find the problem soon. The car runs great. only has 117k miles on it. I was wondering if i install a new alarm will it bypass the F(*^ED up factory alarm? please help so i dont end up selling this car.

Sorry man I can't help with the MKII's alarm since I don't know it well enough. All I can say is to find the broken sensor that is causing it to go off and replace it.

I followed the directions posted earlier, locking the door and waiting, cycling the ignition switch several times, no go
Does anyone have any suggestions before I drive the car to a Toyota dealer and spend too much money??
the drivers window has a sticker about a Toyota anti-theft system.

look for the fuse of the alarm system and take it off.

Take off the fuse for the alarm system is in the pannel driver side or follow the allarm 12 volts lines.
For the car which doesnt start first check the connector near air filter.
Check the water temperature sensor see if the plastic connector are rotten dry ,this will disconnect the sensor and trigger not to start,located near the thermostat.looks like copper brass,I got it parts from toyota camry 1992 2000cc .
