Question Turns but wont start!

i just changed my headgasket and as i put the head back on... i am having trouble turning the car on!!! As i was placing the timing belt back on, i turned the cam and crank to TDC counterclockwised so there is no backlash, so i know the timing is correct, i also smelled and saw some fuel on the spark plugs, and as for ignition i havent checked that yet!!!! if someone has some ideas please share your thoughts!

check for spark is all i can really suggest
cause if its cranking, and theres fuel being sprayed, only other thing that would really keep it from starting would be no spark....pretty sure atleast....

Hooked up the cam and crank sensors? That will definitely prevent it from starting. Also, you should be turning the motor clockwise, not counter clockwise.

Possibly out of time or a bad crank/cam sensor.

car will start and run without cam sensor plugged in. im betting you either forgot to plug something in or you spilled coolant on a sensor and its not working. just do a long check to make sure everything got put back.

check sensors near the water pump area...check vacuum lines around the throttle body, there are alot of things that go there. this might be silly but are the ignition coils plugged in, do you have spark plugs, is the intake temp sensor plugged in, it has to be something you didnt plug back, and alot of little things i can think of would cause starting probs.

look, its simple.
It ran before right? And now it dosent.

WILL IT CRANK? not start but will the starter turn the engine?

Do you have a check engine light on?

is everything hooked up CORRECTLY ??

HOw exactly did you get the timing in line? just putting the cam sprocket with the tdc in the up position is NOT ENOUGH. If your even off by one tooth in the timing belt, your not going to have stuff working right.
From what you described, FUEL ON PLUGS, it screams timing issue. Crank the engine and hold it in the start position so it keeps cranking over, and CHECK THE TIMING WITH A LIGHT.

Agree, chances are all sensors still working.

I'd be looking into this as something not hooked up right or maybe a accidently cus or loose wire while install.

Basicaly you need to see where you missed on install.

the starter turns the engine!
everything is hooked up correctly!!!

i aligned cam and crank to tdc... it should be timed!!!! but checking it with a timing light is something i will have to do!

thank you

i am double checking all the sensor connections but so far everything looks good but i will keep checking, i am positive its something very small and i missed it, that happens to me!

It is something small for sure, also double check the timing or ask someone who knows to check on timing. It can be tricky.

Just curious as to why you replaced the head gasket in the first place? Coolant or oil leak?

aight im not questioning your mechanical abilities first off.

have you checked your compression yet? if you dont have a proper seal your never going to get it to start.

Timing light is a must, go rent one from autozone or something. How did you set the timing? turn the crank by hand till it real tdc then aligned the sprocket or what? im pretty sure you need to set it to the #1 pistons tdc... not sure on that tho...

do you have spark?? you dont neeed a toold, just pull the plug out, and attach it to the coil, as it would be if installed in the head, then have someone crank, and look for a spark... you just need to make sure all the elements are there before you get into more complicated stuff.

AIR FUEL SPARK..... its life and what engine run on.. make sure you have them all first..

compression, spark, fuel, air. its sounding more like a timing problem. did you do everything acording to the service manual?

i agree. like said before, just putting the engine at tdc wont time it, there should be marks on the cam sprocket and crank line those up, also what did you put at tdc? 1234? should be 1.

yeah, as far as ive experianced you need to set everything in line with TDC on the #1 piston. IF you dont..... car no worky. Hondas will run forever but they can be finiky also ya know.
just do yourself a favor, redo the timing, no matter how goodd you think you have it, pull the valve cover, and set that puppy to TDC with the #1 piston, i am pretty confident youll be back in businnes after that.

Never tried it on stock ecu but it won't with the aem.

I wouldn't go to the length of resetting the timing, I would put the crank pulley at tdc and pull the upper timing cover to make sure the cam gear marks are lined up with it before you pull the timing belt back off.

well thats the idea, you cant adjust the timing correctly without yankin the cover, just bite the bullet and take it back apart , at least for peice of mind...
