car alarm wont let car start

[Needboost]

im interested in buying a 1887 turbo but after talking to the guy he said that something with the alarm system is causing the car to not crank. is there a way that the alarm can be disabled or disconnected to try and start the car

 

[Nick M]

Yep.

1. Fix it.
2. Remove the interuption in the starter circuit.

 

[Needboost]

can you explain it a lil more like where it is and where the interuption may be some people have said that by just turning the key a certain way can reset it and allow it to start

 

[jetjock]

How many ways are there to turn the key?

 

[Nick M]

See the blue wire with the red tracer that says "USA"? Ground it. This is an 89, and your colors may be different. Get the EWD for your year.

look under the coloum for a relay wired to the alram. replace relay and try again, could be bad relay. if its a 87 should be a yellow wire hooked to the realy. cut and rejoin it,

Disable the shit stock alarm system by removing the comp and ground the blue w orange stripe like nick said then install after market alarm. Much better yes? Yes.

 

[Needboost]

the guy said that the car hasnt had a battery in it for about 2 years would that clear the ecu memory of the alarm being on or will the alarm control system still remember it? im going to do what hvyman and shaeff said just remove the alarm comp and ground the wires

The ECU is not involved in the factory alarm. Nor does the alarm box itself have any memory, volatile or otherwise.

I never had many problems with my stock alarm. It went off a few times when unlocking the hatch but after I repaired the cause that stopped. The only other things I did to it was fix a weak spot common to many factory alarms, add a couple of sensors, monitor the fuel filler door, and rewire the interlock to disable the fuel pump instead of the starter. All were are easy to do.

Btw I'm always amused at the gyrations people suggest to reset the thing once triggered. Apparently none of them have read an owner's manual...

But JJ, you have to turn the key in the passenger side, *then* the hatch, and finally in the driver door. Then you have a fully unlocked car.
