Hi...

Can any one please tell me whether a bad Intake Air Temperature Sensor
(IAT) or a bad TW (Coolant Temperature sensor, or Water Temperature
Sensor) will cause the engine not to fire up?

I've read that these two sensors can affect injector pulse width? It
seems that I'm getting too much fuel into the combustion chambers, thus
after a few cranks of the engine, the combustion chambers are flooded
(spark plugs soaking wet with fuel) and the engine won't start. The
spark plugs do produce strong sparks. So I'm quite sure it's not an
ignition problem. Iit seems like more fuel than necessary is injected
- that's why I'm wondering whether a bad IAT or TW can cause this
problem.

Thanks.

They will have no effect on engine startup.

Is the spark properly timed?

Has anyone bought an Oxygen sensor from this company?
They have the best price I've found for a direct replacement
on my 94 VX.

I'm trying to put together a small tool kit. Something to fit in
the area above the spare. I'd like to have enough to cover any
quick fix situations.
I've come up with : Combo screwdriver, my small ratchet &
a few sockets (which ones most usable for a Civic?), medium
Channellocks.

So, what do the rest of you carry?

8 mm, 10 mm, 12 mm, 14 mm, 17 mm.

If you must eliminate two, eliminate the first and last.

Add a medium-sized crescent wrench and small hammer.

My AAA Card ;-)

I see the NTK oxygen sensor for a 94 Civic VX for $80 at
this site. But I don't think that's a genuine Honda sensor,
and so it's a real roll of the dice.

Try https://www.automedicsupply.com for OEM sensors at good
prices. I have used it for an OEM O2 sensor for my 91 Civic
a couple of years ago. Good service. No problems with the
sensor.

That VX a California compliant one?

No, a Kalifornistan sensor is much cheaper!! My red jewel is a
Canadian built 48 stater.

This is the one I'm looking at. It has the correct Honda part number.
Most sites want $300 + for it.

I can't check the ignition timing, since the engine doesn't run. Is
there a way to check ignition timing without the engine running?
Thanks.
