92 Honda civic lx sedan Stalling and at times won't start.?

Question

92 Honda Civic lx 5spd sedan, stalling and at times won't start.

I have replaced the following= fuel tank, fuel pump, main relay
When I accelerate thru the gears ....the car bogs
The car won't start sometimes...... if it does start it will snuff out. I wait and restart and seems to run ok.

Does it need a timing belt adjustment?

Answer 1

yeah i had the same problem a month ago its ur fuel pump even though u have bought a new one u probaly installed it wrong our its defective so i would consider u take it for a test

Answer 2

First of all, the timing belt is not adjustable so you can rule that out.

It sounds as though you have one of two things going on provided your previous repairs/replacements were done properly and that the car still had the same problem after each.

the first and primary suspect is the ignition coil. The ignition coil is a step transformer that takes the 12 volt battery voltage and ramps it up to about 30kvolts. when the ignition coil starts to break down you have a less powerful spark at the spark plugs and hence an incomplete burn. You may have spark when you test for it, but it will be weak and ineffective in firing the plugs to burn all of the fuel. That would be the first thing to check or replace. Also, make sure that the regular ignition components such as the distrubutor cap and rotor are in good condition; a cracked distributor cap or burnt rotor could cause this as well.

the second thing though more remote a possibility is that the valves are terribly out of adjustment. the valves on that engine should be adjusted every 15,000 miles. that adjustment is the most critical adjustment in terms of engine power, performance and fuel economy. If you can't remember the last time the valves were adjusted then that could be a possible cause as well.

a third possibility though remote would be a restricted catalytic converter. typically honda catalytic converters don't plug up like the domestics but it could happen. you would hear the car 'roar' as the engine trys to exhaust the spent gasses out of the intake when this happens. If the engine doesn't seem to sound louder than it did before this started happening then you probably don't have a restricted exhaust.

I think you'll find that the problem is with the ignition coil, distributor cap or rotor.

hope that helps

Answer 3

when it does not start what does it do since it could be from a plugged exhaust to a sensor like the map sensor not reading properly....
