My Range Rover has been in the shop now for about 2 months. I have replaced the Becm nd the crank position sensor. All the computers are talking but all it does is crank and crank. Can somebody please point us in the correct direction. 2000 4.0 SE

Perhaps the dealer ought to try a security relearn on the engine ecu,Bosch equipped cars will crank but give no sparks or fuel - its the earlier gems ones that wont crank when the security code is lost.

I know it is obvious,but did they reprogram the new BECM with your old data when they replaced it?

Looking at your service manual find the wire that goes to the B+ Measure from this wire to ground for the DC supply voltage. Measurement should be taken on the sensor side of the connector. Ground connection as well. Then, try starting your car again, maybe 3 or 4 tries and surely it will start.
