Default Head Gasket

I just replaced the head gasket put the motor back together and plugged in all the sensors. Went to start the car and it cranks but won't start. My dad says maybe its the timing well I put every thing in just like I took it out. 1st cylinder on TDC and everything and it just won't start. I was wandering if anyone could give any insight.

I replaced the 3mm headgasket with the stock headgasket when the 3mm blew. I feel pretty safe doing this because I am only pushing 8psi and I had a couple of members say that they have their's up to 15psi on the stock headgasket. Im thinking its not getting any compression.

if you have he helms manual, i would go back and double chaeck all your steps, make sure fuses are good fuel lines are connected......i know its the obvious but sometimes it the obvious that we over look. Just go back and double chaeck everything. you will figure it out just be patient

Okay so I go back in and check all of the fuel lines and sensors and everything is connected but 1 sensor I am looking for where it connects and find nothing. Now I know its not just a floating sensor. I think it might connect underneath the intake manifold and I just cant see it. So this week I am gonna take off the manifold again and try to get it connected and see where that takes it.

If the timing is off wouldn't the car still try to start?

If the timing wasn't too off I'd say it would run horribly, but run none the less. An older Civic of mine jumped timing, it wouldn't hold an idle but it did run.

As others have suggested, check your basics. Fuel, Spark, fuses, etc. and go from there.

I would check the wire harness grounds, and also the plugs to make sure they're not fouled-out.

you brought the motor to TDC but did you set timing at the head?
did you cross fuel lines?
how does it sound while cranking?
