There is no fuel pump relay on the CRD...unless you have fitted one yourself.
You have two problems....ignition switch does not actuate the starter.
Secondly, if starter is actuated then it does not start.
By jumping pins 30 and 87 you have proven the starter and battery are OK.
So maybe the Starter relay is faulty or fuse 28 under the hood has blown.
You need to check with a Voltmeter that you get +12 volts on both side of fuse 28 when turning the ignition switch...if not then the actuator pin is broken or the ignition switch is faulty.
If this +12 volts is on fuse 28....you need to check that pin 85 on the Starter Relay is at Ground....the Dark Green/Orange wire.
You see that this wire has to go to ground via the ECM which is checking the switch on the Transmission (assembly Transmission Solenoid/TRS) to check that you are in Park. If you ground this Dark Green wire then the Starter relay should energise when turning the ignition key...make sure you are in Park!
Do you have the anti-theft SKIS system installed? You should have a "Key" symbol or a small red light on the cluster that goes on briefly when the ignition is ON...this means SKIS is installed.
The light should go out after a few seconds. If it flashes then the SKIS system has not recognized the chip inside the key...engine should start and run a few seconds then shut down. If the SKIS does recognise the chip in the key but the ASD fails to energize then the SKIS light stays ON and the engine turns over but does not start.
So check if your AS relay is energizing...you can swap the ASD relay out or also jumper pins 30 and 87 together and see if the engine now starts.
Reasons for engine not starting are:
ASD relay not energizing.
Air in fuel at the fuel filter.
Bad Crankshaft Sensor.
Bad Camshaft Sensor.
Bad ECU or bad wiring.
The bad wiring that Samse2101 is pointing to is a known problem on the 2006 CRD only.
Here is the circuit diagram for the Starting System...this is for the 2006 model but should be close to the 2005 model.
You can download the complete 2005 Service Manual here..includes all circuit diagrams. Note that the Export models have a few differences to USA models!
Some owners recommend also downloading the 2006 Service Manuals...each one has a bit of information that the other one has missing.
