The issue that you are describing is consistent with a failed crankshaft position sensor and is very common on this vehicle and keeps the fuel pump from working.

Hi Mike thank you for your reply is this a big job? where is the sensor?



No this is held on by one bolt and one electrically connector and located near the crankshaft pulley.
