Hi guys, I have a 2001 Freelander 2.5 V6 KV6

Bought it only 1500km's ago, has been running fine, all of a sudden decided it doesn't want to start. Cranks but not firing at all. I have changed the ECU which didn't do anything. The engine runs on the spray starter fluid so there is spark. I have tried a noid set with the injectors and it seems they aren't firing at all..
Would I be right in thinking a possible crank or cam position sensor failure? If so how do I know which one?

Thanks
James

 

Possible but what about fuel pressure and power to the injectors. Has a plug come undone, is the wiring damaged. What about fuses? Start with the easy stuff. What a noid set?

 

Fuel pressure is fine, all wiring and fuses are ok.
The injectors are just not firing..

 

Sry just trying to offer Encouragement, I guess you could unplug the crank angle sensor and use a multi meter to check for signal while cranking on the starter motor. There is a cam sensor as well.

 

the injectors wont fire if there is no fuel pressure?

 

My issue came up on a 2003 freelancer v6 with the ms43 engine control. Vehicle had a crank no start condition, vehicle had good fuel pressure but no spark or injector trigger, costumer had installed new crank and came sensor. After many hours of testing and changing sensors again found that the sensor style for the camshaft was updated and the two wires to the engine control needed to be swapped. After the swap the vehicle started.

 

An 8 year old mystery solved.

I'm having misfires and injector codes showing up on my 2004 Freelander V6 when warmed up, also yesterday when it really started to act up after getting it good and warmed up after a 10-15 minute drive it had the F4 on the dash display, also the hill descent warning light came on. Turned the key off and back on and it went away. Still had the misfire though.
I removed the CKP Sensor from the engine, cooled it off and stuck it back in the hot engine, and it ran great for about 30 seconds before it started acting up again, I am picking up a new Crank Sensor this morning.
I had read elsewhere that a failing CKP Sensor can cause transmission issues as well due to the Transmission ECU using the signal from the CKP for transmission/torque converter input speed.
