2000 Accord just cranks does not start

Thanks in advance for your support

My 2000 v6 accord does not start. The motor cranks until I release the key
but does not start. I had this problem once during the summer and after the
car sat for 4-5 hours it worked fine and has continued till today. It is a
bit colder out now and the car is parked outside. I installed a new battery
not for this problem but strictly because of the age of the previous one and
winter temps.

Almost seems as though the motor is not getting fuel. Oh BTW I did not
step on the gas prior to starting and the car is in park.


Any suggestions:

 

Is the green imobilizer light flashing while the car is not starting. The
imobilizer units in these sometimes fail in this fashion.

 

gump,
Read the part in the manual about 'lamp check' for the dash lights.
Then, while you're doing the lamp check, listen to the fuel pump run for
two or three seconds. If you don't hear something running, you may need
a new MAIN RELAY. This link will give you the symptoms (which are
temperature related) and the fix:

You can do a Google search for the term MAIN RELAY HONDA and you'll find
MUCH discussion about the problem....

Had the same problem. Let it sit for a couple ofminutes then floor
the accelerator pedaland crank the engine. Works for me.

 

===============

If it really is the MAIN RELAY, just smack the dash with the key in the
II position. You'll hear the relay run and car will start when you try
it (until next time it acts up).

grump,

I thought about another suggestion. Last spring, our Ody had a leaky
injector and the symptom is the same as bad relay: Overnight the
injector leaks until pressure drops off. Engine is FLOODED. It was so
bad I thought the timing belt was broken because it wouldn't fire or start.

I read the manual and found the part about high altitude / cold starting
/ flooded engine. Held the pedal to the floor and cranked it for five or
so seconds and it started to fire... took several more seconds to stop
sputtering.

We cured it by running some ethanol enhanced gas thru it to clean the
injectors. Injector cleaner would have done it too.

Let the group know if this helps.
