If your Honda is naturally aspirated/carbureted, then your only problem is the fact that the diaphragm that squirts gas into the venturis is not operating. Maybe just need to replace said diaphragm or maybe just an adjustment to make it squirt sooner is all it may need. This initial gasoline squirt is what keeps the engine from dieing when you stomp the throttle. Understood?

SOURCE: 91 honda civic dx. Starts, runs for a few seconds then stalls

Try pounding on the gas tank with a rubber mallet or similar tool. (careful not to dent the tank) Try starting it. If it runs, replace the fuel pump (it's nfg). I've diagnosed numerous fuel pumps this way. Remember the pump needs to be replaced, if you drive it, you don't know when it'll fail for good. Hope this helps. Please post the results.

SOURCE: 2005 honda civic, suddenly no power to anything

Yes, there is a main fuse. It is located in the fuse box under the hood.

A faulty ground wire could also cause this.

Checking the continuity on each one separately (with the circuit deenergized) would be my first check.

SOURCE: when engine warms up my 93 civic stalls on acceleration

Possible that the fault can be with the fuel pump as the fuel pressure drops off when the pump is hot. In this case you need to measure the fuel pressure when the enigne is running after a cold start and then after it gets warm. Also the same applies to the ignition unit in case the spark decreases or fails when the coil or the ignition system is warm.You can test this with the plug removed and cranked to look for spark.

SOURCE: Sudden loss of power, Backfiring, starts then stalls

The car still runs and drives, just no power and shakes badly during acceleration. Could the timing belt have jumped? Could this happen while driving yet the car still runs?

I have a 2003 Honda Civic and is jerking when I accelerate suddenly

Most repairs are covered by AT LEAST A 90 DAY WARRANTY. Get that car back in there and tell them it's been having issues since you took it back from them. Ask them what they are prepared to do for you before you get legal help. That should get the ball rolling in the right direction.

Honda Civic 1.5 Vtec Randomly Accelerates When Cruising

Try contacting the Dealer. There was a big investigation about some Hondas suddenly accelerating. Here in the U.S., there were Lawsuits and deaths from sudden acceleration.

Check out the site, I believe, Allaboutautomobiles.com, which has the National Hoghway Traffic Administration info about each car and defects. This site has Recall #s and Consumer complaints listeded.

I hope my solution is useful.

1991 honda civic not running on third cylinder. Have changed plugs and they are all firing. What could it be? Someone told me a burnt valve but it started acting up all of a sudden.

You could have bad compression rings on that piston. I would do a compression test on that cylinder, also I would check the fuel injector.

Sudden loss of power, Backfiring, starts then stalls

Your timing belt could be broken. You want to have this checked as soon as possible to prevent any further engine problems.

No fire

first thing i would check would be your spark control module.Located in the distributer under the rotor.take it down to your local autoparts store for testing.have them test it three times in a row to get it to operating temp.if it passes then check your coil with a multimeter.
