2002 Honda Civic cranks but will not start.

Asked by Nov 10, 2016 at 08:05 AM about the 2002 Honda Civic EX

Question type: Maintenance & Repair

I have been fighting this issue for a long time. I will try to explain what is
going on. My son has a 2002 Honda Civic EX. When trying to start the car,
the motor cranks great with a lot of turnover power but the car will not start.
It is like the car is out of gas. I have changed the fuel pump, purge valve,
Vent valve, crank sensor, cam sensor, battery and connections, alternator,
Spark plugs, fuel cap, Fuel pump relay, and took the car to the dealer
where they did a valve job for $300. I have hooked a pressure gauge to the
gas line going into the fuel rail. The pressure is 45 psi when cranking. The
car will start sometimes like there is nothing wrong. When the car starts it
idles good. Sometimes when driving the car, it has a small miss in it. When
the car starts it runs and drives fine except for the small miss at times. Most
of the time it cranks but will not start. I have noticed that the problem
seems to be worse with the cold weather. I was thinking about replacing
the computer. The way I understand it, is that if I buy a used computer I
have to take it to the dealer to get them to program it. I have run out of
idea's on what to do next. When the car is running I get over 14 vdc on the
battery. I have removed one of the spark plugs after I tried to start and the
plug seems to be dry.  Across the injectors I have 11.2 ohms. I hooked up a
led across the injector wires and the led pulses slow when trying to start
and pulses fast when the car finally starts. I checked the voltage to ground
to one of the wires going to the injectors and got 12 vdc as the engine was
trying to start. It took several attempts to get the car to finally start. The 12
vdc remained even as the car started. I shut off the car again and after
several attempts to start the car, I removed a spark plug and it was dry. I
even tried to start the car without the plug and when the car started I did
not notice a lot of fuel coming out of the plug hole. What should my next
step be? Thanks Everybody I have spoken with tells me that I have
changed everything they would have changed.

It sounds to me like you have a problem with the crankshaft or camshaft sensor, or the wirring circuits to these sensors.Have you tried pulling a plug and check the ignition coil to see if you have spark whenever the car fails to start?

Forgot to add that when a crankshaft sensor fails the PCM will automatically keep the injectors from injecting fuel on some cars. The fuel pump will sometimes still work and the pressure is good and all but the injectors will not work unless the PCM is recieving a signal from the crank sensor.

I have already changed the crank and the cam sensor. I have also confirmed that I am getting spark. I have not check the wiring to the sensors. Not sure how to do this. Thanks

Could the PCM be bad?
