i installed sr20det red top and harness, it starts up but will not turn off with the key, i have to pull the 80amp fuse before the engine will shut down. Any thing that i might have cross up, wrong plug connected. Any ideal.

91 240sx hatch is the car.

 

Didn't you have this problem before?

 

yes, but still no luck. some how its getting power feeding back to keep the car running. I disconnected ING switch, ING relay and will not shut down. the only way it would shut off is by pulling 80amp fuse.

 

I can't recall in your other thread if you tried a different ECU. If you haven't, try another one. I came across one once, same issue that you're having. The only way to shut the car down was by pulling the Alt. relay.

 

wrong ECU. seen this quite a few times

 

I used the same ecu not a different one. i did wire up the maf wrong at first and burnt a diode in the ecu, but after fixing the maf issue the car started but then will not shut off. do you think that the ecu is keeping the car running.
