Hello i have a 1995 nissan pathfinder , i have been experiencing hard starting and engine vutting off afta 5 min of driving. I put a new ignition coil on but still have the same problem . I notice that when i try to start it and it doesnt want to turn over and i have the key in the on position the ignition coil is making sparks to the distributor so i pulled the wire from the ignition coil off of the distributor and it arcs at the end of the wire then i went to the ignitition module and unplugged that even with that unplugged i still hear sumthin ticking even when the engines not running

When ignition is turned on, the coil should not keep sparking unless the ECM is sending the wrong signal to the power transistor to trigger the ignition coil.

Unplug the ECM and test if the sparking continues.

This is something that defies logic and I am afraid I am not able to help.

Curiously, how did you monitor the sparks and injectors? With injectors clicking and fuel pump staying on, the cylinders should be flooded within a few seconds.
