Changed head gasket in a 2000 civic and car wont start now?

ok.. i changed the head gasket on my 2000 civc ex and now it wont start. as soon as i finished the install the car started right up and then i gave the car some gas up to about 4k rpms and then it started to stumble and run like a misfire and cut off. i checked the compression the fuel and the spark and have all 3. when the motor is at top dead center on compression stroke the rotor button in the distributor is pointing at the #1 plug spot as its supposed to be. when the distributor is pushed back towards the fire wall as far as it can go, it acts like it wants to start but doesnt... i am stumped!! have no idea what to do next... if anyone else has had this problem or knows how to trouble shoot this problem please let me know asap!!!! THANK YOU!Changed head gasket in a 2000 civic and car wont start now?Check your timing marks again on the timming belt sometimes they slip. Or try to take the distributor out and just move the rotor one way or the other untill you get it You are not stupid dont even think like that!

OK, lets see. It's got fuel, spark, and compression. Um, what could it be. Have you check for AIR. The fuel part of this equation is actually air/fuel mixture, with out the air the fuel won't ignite.

The problem could be some blockage in the air inlet tube or air filter box. I have had vehicles with mice nest in the air box causing the vehicle not to start. I had a truck last spring that is parked all winter, the guy got ready to pull it out and start driving it, but it wouldn't fire. After about 2 weeks off fighting with it, he ask me if I could take a look at it. I opened up the air box and a hole family of mice jumped out. We cleaned out the air box and put in a new filter. The truck runs fine.

Another possible problem could be a dirty Throttle-body or idle air passage inside the TB restricting air flow causing the engine to flood out and stall. The TB can be check by just opening the throttle plate and checking to see how much carbon is built up inside.

Hope this helps. Christopher
