2001 Disco II - no spark, no fuel pressure
Any help appreciated.
2001 Disco II, Turn the key and the engine turns over as normal but does not start. I have checked the fuses and relays they are good. Replaced the cam shaft sensor, crank case sensor. I have tested the fuel pump by bypassing the fuel pump relay and the fuel pump is working. I have also tested the rollover/fuel cut off switch. It is pushed and there is voltage through the closed circuit.
When starting I have verified that there is no spar to the spark plugs and there is no fuel pressure.
No "P" codes shown.
Help. Finally about to take it to the shop.

RE: 2001 Disco II - no spark, no fuel pressure
Which relays and fuses did you check, and how did you check them? From the wiring diagram, I am not seeing a whole lot that will kill both systems. Take it to a shop or dealership, have them use a scanner(with real-time display or T4(testbook)) to see if the crank sensor is sending a signal to the ecm. You said you replaced the crank sensor, so if they do not see an rpm reading in ecm real-time display, then it is likely that there is no power to the sensor. Check the main relay, fuses 1 and 2, fusible link 8. Rap on the ignition switch while cranking(I had a Freelander today that had no brake/reverse lights, radio, wipers when running due to opened ignition switch contacts after cranking that relaxed after turning ign off then on and when rapping on it when running). Possible faulty ecm.

Posting the fix is definitely a big help to everyone. It also goes to show that if you are having problems having changing something to go back and put the old part back in to see if that is causing the problem, or as in this case make sure the new part is installed properly.

A litle up-date here on mine..... Today I replace the cam sensor and crank sensor and still not getting any spark or fuel pressure... I swap the computer from another 2001 and still the same, no spark and no fuel pressure...... also check the reset button by the firerwall..... It looks to me that had something to do with the alarm or something
