Ok I drove my 95 country HO 4.0 home last night. Would not start today, turns over fine. I have fuel, no spark. No spark at plugs or coil. I checked all fuses and swapped relays, no spark. I just installed the sensor in the distributor, think it is called coil pick up or cam sensor. No spark, whats next?

 

crank sensor

 

anyone now how to test a crank sensor/

 

Just replace it and be done with it.

 

x2 on both of these answers.

 

I got my xj for an awesome price because after driving it for a bit it would not restart until it sat for 1 to 1-1/2 hours (no spark).
It was the crank sensor.

 

Just replace it and be done with it. Well that was what it was, just got done with it. Pleasant little sensor to get to. Thanks guys. Oh one other thing how long do these last?

 

Until they fail.

 

Sensors are sensors...there is no telling how long they will last.

 

In other words........... SOON....

I found that it is best just to keep one in the glovebox....... I've replaced them enough, that I can now do it in under 3 minutes!!!!

 

hey i got a simular problem. but im goin backwards of what youve done. i changed my CPS and nothing. how do you change the CKP or cam position sensor, coil pick-up what ever ya wana call it....

 

On my 95 it was under the rotor in the distributor. Just pulled off the rotor, umplugged the wires and it came right out.

 

Yep, it's that simple.
