Default camshaft sensor

hello Bob,
Well, I got a new sensor and lead and made the long 120 mile journey with a very obliging friend but it turned into a wild goose chase. I installed the new sensor plus lead and cleared the error on my Autel machine. Car wouldn't start and came up with sensor fail again. I noticed that the petrol pump was not starting up. I disconnected the battery and shorted the battery leads together for about 5 seconds. That seemed to clear the ECU memory but car still would not start so abandoned the project.
Do you have any ideas. I thought the cam sensor failure meant that the ignition system did not initiate but the petrol pump would work. I think I recollect that a faulty crankshaft sensor can cause the petrol pump not to start.
Do you have any theories? The frustrating thing is that the car was running beautifully until I stopped to check oil and water.

Fred
