honda wont start

my 1990 honda accord will not start. I really wants to but as soon as
you let the key go from the start position to the run position it dies
any suggestions

 

Almost certainly a broken ignition switch. Honda once had a recall on
Accord ignition switches, but I believe 1990 is too early to be covered
by that recall.

 

You forgot the main relay problem.

A cheap fix,no parts needed,just a soldering iron and solder.Save you $50.

 

If I understood the OP correctly, the engine consistently catches in
"START" and dies again in "RUN". This is consistent with a failed
ignition switch. With a failed main relay the engine would not start at
all, or it would die at random. That said, I am very good at reading
posts in a way that matches my own hypothesis, and it could very well be
that it really is the main relay.

To find out, one could jumper the positive terminal of the coil directly
to the positive terminal of the battery and start the car. If it starts
and keeps running until the jumper is removed, it would indicate failed
ignition switch.

 

You should be able to find out via the following listed web site whether
or not your vehicle has a factory related ignition switch problem. I know
that many 1999 Honda Accords were recalled to replace the ignition
switches.

My 91 Honda had this exact same problem and drove me nuts. It WAS the
ignition switch, and I was actually able to take the switch apart and file
down the contacts which had become pitted. Was a pretty easy job, and pretty
easy just to get to the switch if you would rather replace it. Of course,
don't try opening the switch if you're not good at putting things back
together exactly how they were, I recall a spring went flying when I opened
it up. Anyhow, the haynes manual had the table displaying the continuity you
should be getting at different key settings - which should confirm this for
you before you pull the car apart.

 

Incidentally, I have heard some theorizing that at least with this type of
problem, a heavy key chain can be a culprit. Admittedly, I used to have
12-16 keys on it and during city driving their swinging around can put
stress on the switch and cause little arcs as the contacts lift ever so
slightly. Just something to consider.
