I have a 90 dx that wont start when left outside in hot temps. flashing code 16 i replaced the injectors and the problem was gone for about a month its not starting again and once again flashing code 16. car runs fine when running any ideas

 

get yourself a backup main relay and reset your ecu then you should be good to go

 

main relay is in fuse box on pass side rite?

 

its under the dash on the driver side by the hood release...just get a 10mm wrench and unclip it and replace...looks just like this below...!!!
