86.5 Manual non-turbo will not start!!
 
This is the second time in a month this has happened. I get in the car turn the key and nothing. All the lights come on, radio comes on but there is no crank or anything. I've tried to arm and then disarm the factory alarm but still nothing. Anyone have any ideas?

Any click noise or anything from the engine bay area? Usually if there is 0 noises anywhere its the alarm, sometimes you gotta try to ar/disarm it a few times.

Got it started this morning. Apparently a wire came out of the factory alarm, probably the start signal to the ECU. Tried to unplug the alarm but the car wouldn't start. Plugged it back up and it started fine. I need to go to the dealer to get the schematics for the alarm and figure out which wire is the start signal and bypass it to just get rid of the problem all together. thanks for your reply

Yeah the alarm computer and the ignition are wired to a relay and the alarm comp. allows current to travel through the relay to ground and the circuit for the ignition is swtiched on to the starter

heres the alarm wiring diagram

Beautiful!!
 
Thanks for that link, that will help a lot

It looks like you could just take the starter relay out and connect the ignition wire and the wire going to the starter straight 2gether. Pins 2 and 4 the only problem is that the car would start regardless of the clutch pedal being pushed in or not.
Heres another view of the diagram MK3 TSRM On-Line

I have sorta a promblem
 
This was my dads car gave it to me and he has no idea since hes in phoenix and i in tucson

i was turning and the steering suddendly got hard and the car turned off on me thankfully i wasnt hit but then when i push started it and succesfully got to my location but then later on in the day i came back to leave and i would:
unlock my car
open door
and all the backlights on the gauges and meters went off blinking with a little ring coming from the ignition area then
i close the door and it stops after like 30 seconds it seems that the alarm should go off because it used to go off all the time now it just blinks and when i turn the key to turn it on (yes i do it properly) it just has a wierd click noise at the passengers foot area just a loud click noise and the lights just go on but the doors lock as if it turned on

any help? it just started this yesterday it worked fine before btw its a 1990 Turbo:frown:push starting all my life isnt exactly what i would want to do thanks
