Crank sensor failure is very common on that engine. I can almost guarantee you that this is your problem.

 

This sensor is located behind the driver's side cylinder head, in the block. They often break off when trying to remove it.

Crank sensor failure is very common on that engine.

 

 

IS THIS FAULT COMES AND GOES....i.e INTERMITTENT & HOW TO CHECK IT .

 

 

I WENT TO A FRIEND OF MINE WHO IS WORKING IN ELECTRICAL WORKSHOP AND USUALLY DOING GM CARS, HIS DIAGNOSIS WAS:

A LOOSE CONNECTION OF THE FUEL PUMP AS IT HAS TWO CONNECTIONS , ONE INSIDE THE FUEL TANK THE OTHER OUTSIDE IT.
