How do u run a diagnostic on your ECU. I hav the manual for my 91 na but it doesnt tell me how to read the codes. eg. Watch the light blink or someting.

 

I'm sure you can find the process by utilizing the 'search' feature on this site. It'll walk you right through it.

Thanks guys. I did come across it and did the test. Seems I hav a problem with my Fuel Temp Sensor... Do you think that will keep my car from starting. I mean The injectors are giving it gas but my plugs wont fire. Do u think because that is bad the ecu wont send the signal to the plugs to make them fire???

 

have you looked at the sensor or its connections yet? it probably needs to be replaced. its between the # 2 and 4 injector

it has nothing to do with your plugs either. it tells your ecu to change the fuel pressure depending on its temp

 

and yes, it could cause the problem you have.

 

Well I took out the sensor and ran a continuity test of the wire to make sure that didnt somehow go bad. And then i cleaned the connections on the sensor and the harness and put it back it. Ran the test again and now i get code 55 which means that everything that it checks out it ok. So its possibly my ECU. suppose to try and get one tomorrow off some old car in the back off this guys yard. hope its all a ok
