200sx sr20 key on engine off or on issue please help!!
Ok so I have a 1996 200sx with an sr20 engine... I bought off a friend and inherited the problems that came with it.. Its been doing this for some time and many steps have been taken to try and remedy the issue please help!!
The issue is when the engine is running after a few minutes the engine shuts off. Suddenly. No sputter no spitting just dead. Like the switch has been turned off.
The issue when the engine is off but they key is in the run position after the same amount of time around 5 minutes inside the engine compartment I can hear clicking like someone has turned the key off then back on. I'm stumped
I removed the ECM and ran the self diagnoses on it and then cleared the old codes my friend didn't know how to just to see if it would throw new ones...Nope no check engine no new codes.
Parts Replaced before I bought it trying to rectify the issue
Fuel pump (Complete assembly) has been replaced twice as well as the fuel filter twice
Fuel Pump relay
Fuel pressure regulator
Distributor cap and button
Vacuum lines completely swapped out
Mass air flow sensor and air filter
Throttle position sensor
Alternator and battery
Harmonic Balancer..(I know not related but was a bad part at the time and trying to be thorough)
I am leaning towards either the ignition switch or the ECM.. But this is only my first day working on this car and its a shot in the dark at most for me..
Please someone throw some ideas at me ....
