I have a 91 civic lx 1.5. I just changed the distributor, fuel filter, 4 plugs AND both fuel injectors(dual port system).
The car seems to run fine, even though it will not start up right away.
But still getting that code 16.
I am smelling no gas, and it sound like the injectors are clicking very nicely.
Anyone have a suggestion on what i may need to check out to get this code to stop?

As with the problem starting, could it be the crank to cam timing may be off a bit?.
If so, is this something i can adjust easily?.

 

have you reset the ecu since you replaced all that stuff

 

What is your fuel pressure?

Have you checked all the grounds - mainly the one by the thermostat housing?

Do you have a spare Main Relay you could swap in/ have you checked it for cracks?

Why do you make new threads when you have one with your history/work done already in it?
