Hello, I have an issue with my 1995 XJR.
While driving my engine suddenly stopped and the transmission light appeared. I tried to start it again but it only cranks. Then I tried to restart the computer by removing the battery terminals and after putting them back again the car stopped cranks as well. I tried to press the crash switch but it didn't help. The fuel pump is working fine as I can hear it running, it has fuel, the battery is OK. I, also, move the gearshift on Neutral and tried to start the engine - nothing again.
When I turn the ignition on, all the lamps turns on for the check and after turning off, the transmission light appears again. After trying to run the engine the SRS Air Bag light appears, but nothing else happens.

I will appreciate any suggestions and help related to the problem.

Thanks in advance.

 

I would first check the ecm relay because its the easiest, but you should second check the crank position sensor. had the same problem with my 95 xjr6.

 

Thank you Jeremiahjaguar. I'll try the relay today. It should be situated behind the right headlight, shouldn't it?

 

ecm relay is behind the passenger side headlight. you can find all the info you need on this site, just look up ecm relay and crank position sensor.

 

I have checked them and it didn't help.
Is it possible the problem to be caused by a bad throttle position sensor?

 

I have realized that the check engine light do not stay after the check...

 

The common no start mantra "What does the tach do while cranking"!
It is highly unlikely your problemis a TPS.

 

Excuse me for the delay answer, I was on a business trip.
I don't remember what the rpm did when the car was still cranking...
Now it do not move when the car is on ignition.

 

Hmmh. I guess you need to get it to crank again! Are you sure the battery is not run down due to cranking without starting? Maybe clean the battery terminal, and that will also do a "hard boot".

 

Yes, I am sure for the battery. By the way, I didn't have the chance to exhaust the battery, because after two attempts to start the car, I restart the computer by removing the battery terminals, after which it stopped cranking.
Hope I'll start the car soon, because this was not in my plan. I have just bought a refreshing kit for the supercharger ...

 

If you have another key, try that. (security transponder).
