If you still need help with this, please provide info on Alarm

 

 

Brand, Model Number, etc., as it likely is not Factory

 

 

 

Customer: replied 6 years ago.
I believe it is factory!
Expert:  Don 'Mo Lurch' replied 6 years ago.

 

My manual or info does not show "Factory Alarm" available for 1990
There were some Dealer installed, but most were Aftermarket
If it is a Horn sound, then it may be Dealer
If it is Siren sound then it is Aftermarket

 

 

Customer: replied 6 years ago.
Molurch, I jut purchased xj6 never heard alarm; so hard to tell which it may be. any other clues? also do you think alarm system may have shut car down and not allowing it to start?
Expert:  Don 'Mo Lurch' replied 6 years ago.

 

Lets check to see if there is an Alarm first:

Ignition On
Roll down Driver Window
Ignition Off
Lock Doors with Door Panel Switch or Door Key
Be sure Hood, Trunk & all Doors are closed & locked
Wait for apprx 2 minutes
Reach in thru Driver Window & "Manually" (not door panel switch) Unlock Door from inside
Open Door

Does Horn, Siren or Lights flash??

 

 

 

Customer: replied 6 years ago.
Lights are flashing
Expert:  Don 'Mo Lurch' replied 6 years ago.

 

Just Lights?

When the Door is Unlocked with the Key, do they shut off??

Expert:  Don 'Mo Lurch' replied 6 years ago.

 

hello........

 

Just Lights?

When the Door is Unlocked with the Key, do they shut off??

Customer: replied 6 years ago.
lights do not shut off when door is unlocked by key. lights only stop when key in ignition;however car will not turn over.
Expert:  Don 'Mo Lurch' replied 6 years ago.

 

>>however car will not turn over. <<

 

Do you mean engine will not "CRANK"?
OR
Engine will not "RUN"??

 

 

 

Customer: replied 6 years ago.
engine will "crank" but not "run"
Expert:  Don 'Mo Lurch' replied 6 years ago.

 

If engine is cranking & does not run, then it does not sound like Alarm issue

I also noticed you had a question with Richard.
He suggested checking the Crank Sensor & Main Relay.
That would be the first thing to do
