ok i have a 1990 honda civic dx and it starts and runs fine then i shut it off and it dont want to start but u wait a lil it will start then if u shut it off it might start 3 or so times and not start again what can i do

 

When one sometimes cranks but doesn't start, suspect the main relay. Especially if the check engine light stays on while cranking, it should go out while cranking. Replace it or resolder it. This relay is located under the dash on the left side wall of the car just above the hood release lever.

 

i already replaced it it still does it

 

Next things to check would be to see if the ECU shows any codes (if it does, they may be old, so reset it and drive until it won't start again then check codes again). Also take one of the plug wires off the distributor and see if it is making sparks when it is not starting. The engine does crank every time but not start, right?

 

how do i check my ecu

 

and how do u reset it

 

it gives me 16 blinks
