Honda Civic, 2 Minute Run Time
Q:
My 91 Honda Civic starts but will
only run for a minute or two and then dies. The trouble
code flashes 16 times (fuel injector code). I ohmed the
injectors and they are within tolerance. Does this code
include all of the fuel system? Would a fuel pump cause
this behavior? The vehicle has 102k miles on the odometer.

A:
Hondas code 16 for your vehicle does indicate a possible injector circuit problem. The first thing I would suggest is removing the hazard fuse to clear the computer of codes and then reinstall the fuse. Start the engine and see if the injector code returns. If it returns then it is likely that there is an injector circuit problem. If your Honda has a multi port injection you should know that there is a resistor block for the injectors. You could test the injectors all day and if you dont check the resistor block you'd never pick-up on the real cause for the problem. If the resistor block tests good I would suggest checking around just a bit more and not getting yourself too focused on the injector code. The next time the engine stalls, check to see if you still have good spark. If the spark is good how much fuel pressure is there? Often times it's the basics that will provide the answers to an engine just stalling and not starting.
