hello

ive had to change the crankshaft sensor on my 4.0 p38 but while i was waiting to sort it all out (about 2 weeks) i disconnected the Battery so it wouldn't drain.

so today i changed the sensor and reconnected the battery but now the car wont start at all. before i disconnected the battery the car would fire up but would not start (crankshaft sensor problem) but now its fixed its not even trying to start up all power comes on but when i turn the ignition nothing happens anyone know what this might be? thanks.

1. Start by disconnecting each spark plug wire on your engine one at a time while the engine is running. If the engine drops speed or starts running rough when one is disconnected, you know that spark plug is good. If you disconnect a spark plug and no significant change happens in the engine, you have found a bad spark plug.

2. Test the spark plug ignition by disconnecting the spark plug wire from the spark plug. Hold the end of the spark plug wire close to a metal surface. If the spark plug is good, you will see a spark or you'll hear a crackling noise. This means that voltage is getting through the wire to the spark plug.

3.See if there is a spark on each one of your spark plug wires when the engine is cranked. If compression is good, you will have spark on each one of your spark plug cylinders. No spark would mean that a spark plug wire is dead.

4.Remember that each link connected to your spark plugs needs to be hooked up securely. Links include battery cable, ignition wires and coil wires, not just the spark plug wires.

5.Wiggle the link connections from your spark plugs. Then test again. Sometimes it's just a matter of a line connection being loose.

6.Check to make sure that the end of each of the spark plugs is clean and free of any dirt, oil or grease deposits. Sometimes you can just clean them thoroughly and they'll pass the test. But if they still don't test well after cleaning, you'll need to replace them.

wouldnt that be helpful if it was already starting??? :doh: lol
 
Do you mean by "nothing happens" that the engine doesnt turn at all? I asume you do. Check the battery is charged as it could still be flat (cold weather etc). Also check the starter solenoid wire is making a good connection on the starter. If it "clicks" it could be a starter motor fault, give it a sharp tap with hammer. Or it could just need locking and unlocking on the key fob to sort out the immobilizer. Or an engine fuse box problem or a..................
 
Make sure the battery is fully charged, disconnect wait a couple of minutes and re connect, lock and unlock the car with the FOB. Works on my diesel spares dog which lives with a disconnected battery.
 
thanks for the replys but none seem to work.

i thought it would be something small todo with the immobiliser at first but starting to think its something else now but just have no idea what :(
 
No, the eas will not stop the car from starting.

If your car is a pre 1999 petrol, is the check engine light illuminated when the key is in position 2 of the ignition?
The check engine light is on the bottom left of the binnacle.
 
yes the check engine light is on.



been stuck with this problem for weeks now still dont know what it could be a mechanic said i should ring up the dealers and get the code off them. as i was never given one with the car

does anyone think this is the problem? no doubt the dealers will charge for the code to reset the alarm anyone know how much there gonna be asking for? dont want to fork out on this code and find out it aint even that.

and advice is great thanks.
 
I got my EKA code from my local Dealer (Barrets land rover in Canterbury Kent) for free, also gave me key barrel lock set number, paint code and radio code!!
