I bought a used 1995 Jaguar X300 about 2 Months ago. Every time I started back then I would hear a loud noise one or two seconds after the car started, so I decided to take it home and replace the starter. I started with replacing the Oxygen sensors, oil change, replacing coolant, spark plugs, new fuel injectors…
I didn’t start the car for about one month, then about 3 weeks ago when I tried to start it, but nothing happened. I thought maybe the starter died completely and I noticed that the battery was fully discharged, so I removed the battery, charged it and replaced the starter. Today I put the battery back in and when I opened the door the alarm went on and it didn’t respond to my second key fob. So I quickly disconnected the battery, went to get my other key and disabled the alarm after connecting the battery. When I tried to start, still nothing happened.
When I turn the ignition on all lights go on and go off, except the red oil lamp and when I turn to start the SRS Airbag light goes on as long as I turn the key to start.
I already replaced the relay I think is the starter relay with a different one, that didn’t help
I read online that if the check engine light goes off before you try to start it may be the immobiliser (I live in germany and have a european Jaguar, probably fitted with an immobiliser).
Update: I also noticed that the battery (maybe volt) dash only goes up to like a few stripes below half. When it started before it always went up a little above half. Could that be a problem with the battery?
Did anyone have the same problems? Can anyone tell me how to jump start the starter? I thought about trying that next.
Thanks for your help.
