I have a 1984 Nissan 300zx starts ok but shuts down after a couple minutes. starts again ok. you can hear the fuel pump shut off - its not a relay switch - we have checked them all. Unhooked the battery for about 15 min to re-set the CPU but it still shuts off. any ideas? thanks!

If it's like mine, the relay is located on the passenger side fender wall. You should see a set of 5 relays together. It is the first one in the back.

SOURCE: I need to find the ECU relay for an 86 NISSAN 300zx.

The ECU is probably under the passenger seat. The battery also has a fusible link which may be blown. Also follow the battery wiring to the regulator box. This may also be faulty.

Sounds like the warm start choke. It positions the carb butterflies when the car is warm and adjusts the fuel mixture.
