stalling at ignition

if the car (honda accord ex 1993) stalls at ignition or
turns forever, what can that be? I've tried looking at the main relay,
it seems ok. Hotter weather the car is worse off, especially
with humidity. If I throw it into neutral then back to
park I also have better 'luck'.

PS- thanks for the advice from last time. My new server
only allows two days then makes the messages 'illegal'.

I advise you to do a complete tune-up. It could be something else. I don't
know what you mean when you said that you "tried looking at the main
relay--it seems ok." The only way to detemine if the main relay is working
is to test it with the proper equipment. If you don't have the proper
equipment or know how to test it--I advise you to take it to your favorite
mechanic and have them do it. If you want to do it yourself, you need to
get a manual such as one made by Haynes. Try calling Haynes at
1-805-498-6703. The one you need is 42012

 

The factory service manual can be obtained from http://www.helminc.com.
While it may be slightly more expensive than a Haynes manual, it will also
go into much greater depth.

Well,the main relay activates the fuel pump(if the MR is working)."looking
at it,it seems OK" is not going to tell you if it -is- OK or not.

This tells you how to FIX the relay and eliminate it as a potential
problem.

Or you can spend $50 (or more) and replace it.

Then it could also be a worn ignition switch.

 

Hello,

Ok thank guys. I'll probably just buy a new main relay.

Alright,
Well it appears that when i turn on the preiginition; I see the
check engine light on , i also hear the fuel pump turn on. This
only happens initially. After I have it running and try it again
only the check engine light goes on. The fuel pump doesn't seem to
engage and the car doesn't start. Though it only started once when
it was in neutral. Could this tstill be the main relay? The check
engine light never really stayed on for a long time until only
recently only after I had my brakes done.

Also, if I try to get a honda diagnostic setting I get a 'constant'
check engine light. Does appear to have a corresponding id to a
part or system.

I also had the fuel pump replaced by a shop, only to have this
condition carry on.

If the engine actually fires and runs while you are cranking it, then stops
the instant you release the key to the run position, the problem is most
likely the ignition switch.

 

Not exactly sure if it does that or not. I know that when I try
to start it it will fire then die in the span or time while still
turning the ignition.
The question is, why does the fuel pump not engage (after it warms
up) like it does in initial rounds of firing? Where can I get
information on the fuel pump relay online.
Searching stuff with google and altavista only brings up add
web sites. Searching for information on automobile repairs
is terrible on the web!

Thanks,
John

 

The fuel system holds enough pressure for the car to briefly start,but not
enough to maintain running unless the fuel pump keeps the pressure up.
The solder problem on the relay PCB makes it -intermittent-,which is why it
works sometimes,but especially not when its hot out.

In all the time you've spent on these posts,you could have resoldered the
relay and discovered if it was the problem or not.

 

It could very well be the engine's ECU

Humidity effecting the resonse of electric signals is common problem
in a computer
Especially one that was sealed in a box, and over time the seals
are starting to deteriorate

Best of Luck

John,

Read this site carefully. It seems to be your problem.
