My 2003 honda civic ex won't start?

So i was driving on the free way in 5th gear when all of a sudden i just started feeling my car loose power out of no where, I had to pull over because I saw white smoke coming out the back. Since then it hasn't started. I've had the head gasket changed, the timing belt, got new sparks plugs, new crank sensor, and driving belts. And also it would let me go past 4000 rpm before that happened but that was going on for a while. Someone please help

Blown head gasket. Water is leaking into the combustion chamber which explains the white smoke. Some people would say you have a blown motor/engine.

You say you have the head gadget replaced. Was that before or after this problem? If it was before, then it went bad again. Might have been put on wrong. That would explain the white smoke (water vapor.)

We had a Rover 25, am almost sure it, s the fuel pump. It happened to me once. It just lost power the same way. Mine was under the back seat under a small plate, Hope this helps. The Grinder. UK.

  • My 1983 Honda nighthawk 650 won't start with the electric start? I recently replaced the ignition coils because the old ones were getting heat soaked and the bike would die, however now the bike won't start with the electric start it turns over fin and the starter sounds fine but it won't start occasionally it ll start when it's cold or try to but I've been having to bump start it in order to ride it. So what's making it do this? Could it be the kill switch? Or something else?
  • I have a Honda HRX217 push mower. Backfired when trying to start it, now it won't start? It was running, then I shut it off to open and close a gate, and when I went to start it again there was a really loud backfire and now it won't start. It will sound like it's almost about to start but not. Then get progressively weaker each pull. I changed the spark plug and cleaned the air filter. Any ideas?
  • I have a Honda Harmony HRB215 K4 SDA that won't pull start but if I take off the recoil and drill start it, it runs perfect? I have a Honda Harmony HRB215 K4 SDA that won't pull start but if I take off the recoil and drill start it, it runs perfect. I did a compressin test, the pull start only gets the mower to 60psi but the drill gets the mower to 150psi. This mower does have a decompression vale where the ehaust opest about 1/8 of the way. I tore the ead off and checked and cleaned the valves. They don't stick open. Could there be an issue with the decompression valve? Or would it be the piston rings?
  • How come my atv won't electric start but will crank if I push start it? 2006 Honda trx. Doesn't have a pull rope only electric start. The starter motor turns over the engine but just won't start but I'll push it down the yard with it in gear and it will fire right up. I'm so confused by this.
