I have also changed the fuel pump.The car cuts off even while the engine is just in idle mode and while running.It also gives out a shooting/banging sound like a gun going off at the exhaust pipe at the back when it is running.



A backfire through the exhaust is normally a sign of being lean. Since you replaced the fuel pump, did you replace the filter? There may be more than one filter as well. A clogged filter can cause intermittent problems, though normally not at idle.

Also double check all of you electrical connections to and from the ECU and coil. Pull one plug wire at a time and double check for a strong spark. The distributor may need help.

There are many things that could cause you problem, you just have to eliminate one at a time.
