Question about 1991 Chevrolet Camaro
A car that cranks over but doesn't start, in many cases will be due
to a bad fuel pump, a broken timing belt, an inoperative cam sensor or
crank sensor. The first step in diagnosing a no start is to scan for
codes with a code reader or scan tool. Approximately 40% of the cars
towed in have either had a bad fuel
pump or the fuel gauge read incorrectly and the car was just out of
fuel in this . But since it runs and the #6 injectors seems to be the problem then it is most likely an electrical issue. If the injectors don't have pulse
the engine won't start. Lack
of pulse from the fuel injectors as stated before can prevent a car
from running. Many times the cause of
lack of pulse is because of a bad cam or crank sensor. If the computer
doesn't see either the crank or the cam turning, the fuel injectors
won't be commanded to pulse but since the other ones work, I would not think that these are the problem.
So then I would conclude that you either have a bad injector or that it is grounding itself so I would check all of the wires to it for frays and worn spots and if you don't find any, then replace the injector or switch it with another one to help narrow down if it is the injector or the wiring. Let me know if you have further questions on this.
