My 1996 honda civic cpe ex automatic shuts off after it turns on

run circuit wire is in the wrong place on the start switch

is it flooding the operators manual, (all cars) tells you what to do.
it tells you to crank wide open throttle, (bar stool, pedal to dah metal)
this activates super secret unflood mode by which the ECU cuts ALL fuel injections, start now and with cute black cloud at end of tail pipe>
that it was flooding.
the tests are no diff, from 1920 to now.
compresion good.? if it runs perfect ,most times, seems it is.
good spark? you check spark ? and then pulled all spark plugs.
are he soaking with fuel,or all black tips? ever do a tuneup this decade?
bad fueling, there are many tests for bad fueling. ask.

if engine is good.
the EGR not stuck open
the spark is good an all cylinders with good sparkplugs
then its bad fueling.
is the CEL lamp glowing key on,Yes.no
if yes good, if not The ecu has lost 12vdc power.
if yes, then attach any scan tool to near knees 16pin connector
crank engine for 5 seconds, got DTC errror as you release key./
yes , bingo

when you stop a car, hot the ECT reads 180F or more.
does it> if it reads say 50F, IT FILL FLOOD.
you can see the ECT just key on, with any scan tool, no need to start.
there are more. but this is a good start.(no pun)

You have to have power to the brake switch and the key switch to release the park solenoid.
There is an 80amp fuse and a 50amp fuse that powers the key switch.
Have you checked them to see if they have power ?

It appears that the longer time to warm up is because there was no water in the radiator and running for 30 minutes would cause the motor to seize. Check it out.

this happened to me too. Try using the spare key and if it works the old key needs to be replaced or have a new key made from the spare key. dispose of the 1st key

Push the odometer reset button in (the button is near the speedo/tach gauges). hold the button in and turn the key to position two (key in last position before starting) hold the button in for approx 10 secs..it should turn the light off

It is located Under hood, center, upper firewall, mounted in fuel line (basically back of dash). Take note of how it is mounted not to install backwards. Unhook battery ground. Unhook two fuel lines one on top one on bottom of filter.Mark fuel lines top/bottom tape helps not to get mixed up. Remove from clamp. place new filter in clamp noting proper top and bottom. replace fuel lines. reattach battery, cycle key on and off 3 times slowly. (when you turn key foreward you will hear pump kick on. when stops turn off. Do again 2 more times then start.

Sounds like an ignition switch that needs replaced

First check the rotor under the distutor cap. Had lots of problems with the rotor.
