HI, I was driving tonight and my 1996 xj6 stopped running while I was driving. The start up was rough it turned over quite a bit before it started but then drove for 2 miles and the engine turned off while I was driving. All my electrical worked but the motor would not turn back on it turned over but not start. Is this my crank sensor? or possibly some thing else? The engine light came on and so did the motor light.

 

I've moved your question from General Tech Help to X300 forum. Members here with the same model will be able to help.

This is a peculiarity of the X300 and was the reason I sold mine back in 2005 after several occurrences of this potentially dangerous behaviour.

Numerous items stick out.

The Crank Angle Sensor, and/or its vertical connector on the front of the engine are #1 in my book.

Fuel pump, and its relay are #2. The pump is in the tank, and good days job to replace.

Any of the numerous "Ignition Relays" all over the car, but that is waaaaay down the list.

 

ziggydrives, check the ECM relay located at the front of the engine bay right behind the right headlights. Remove the wiper fluid shroud and check the outermost relay of the 3 there. Swap it with the innermost (AC clutch relay) and see if your stalling problem goes away and your AC becomes intermittent or inoperable. If so you need a new relay.

 

Thanks I will look into the ideas given, will let you know what works..thanks.

 

fuel starvation ?

 

Mr. cool might actually be on to something here. The pump has an inlet screen and an outlet filter which can allow some flow, but not enough to keep the engine running. It is too bad the X300 has no fuel pressure test port, so the best way to test this is make sure it is not something else. I would use a Noid tester to see if the injectors and coils are firing, then figure out is I have fuel pressure.

The old standby way to diagnose a failed CKPS is to observe the tach while cranking. If it shows 200 to 300 rpm, the CKPS is probably OK.

 

Ok, got it fixed it was the crank sensor...I think I will also invest in a spare , thanks all....
