How do i reset the ecu on a 1986 nissan 300zx

SOURCE: 1986 nissan 300zx driver power

Did it rain before it happened? (Humidity?) It happened to my 2000 Maxima. A few days later it was OK. I also checked under driver's seat. I thought maybe I was pushing on a wire with stuff I had there..?

you can remove the ecu fuse or disconnest the battery for about 20 sec.if you start it after and the light is still on thats because your ecu has a hard vode that will come back untill correct repairs are made,have a good day DB

SOURCE: timing on a 1991 nissan 300zx

There is no means of setting the timing if you are referring to a conventional timing light. The engine is designed with sensors that sense the angle of the camshafts in relationship to the crankshaft and whether it is on the intake or exhaust stroke on the #1 cylinder. This design is actually a little more complex than that because it has variable valve timing which means that the angle in which the camshafts open and close the valves, change with RPM's This give the engine the best of both worlds. It's like have an engine with cams designed for torque at low RPM and a set of cams designed for HP with a free breathing quick revving engine you would have on a race course. The ECM is constantly changing the timing and injector pulse width based on many sources of input, from, the O2 sensor, air flow, air temp, coolant temp, fuel pressure, RPM's and a host of other inputs.
SO>>>>>>>>>>>> in a manner of speaking, unless you are making reference to setting up the timing chain, everything else is under control by the ECM and related components.
